I just wanted to post an update here guys. I ordered some 245/70's and went with my Rubicon wheels to the local shop. They did fit, however, with just me inside, there was some rubbing. I took the 245/70's off and put on some 235/70's. They look and fit great. I had 4 adults altogether in the vehicle later that day and experienced NO rubbing at all. In my opinion, the biggest tires that can be put on a Patriot with the FD1 and no lift is the 235/70's. All I need to do now is snap some pics...they are coming.

What are the specs on the Rubi wheels??

Im not sure, but these are the rubi wheels from 03-06, and not the current Rubicon wheels found on the new body wranglers (JK?)

16x8" with 5"bs I believe on the 02-06 Rubicon wheels. The problem with wider wheels and less backspacing is the tire/wheel gets pushed out. This creates a larger arch the tire/wheel follows when turning.

Only tires I've seen so far are 215/70/16 which is roughly 27.9" x 8.5" on some rubicon wheels seen here...

AHaaa!!! So, 16 in Rubicon wheels will fit on the Pat. Outstanding!! That looks good indeed.

Summit Racing actually carries an American Racing wheel that is 16x7 with a 5.5" Backspace and is polished aluminum. It's called the "Split" and it's a "split 5-spoke" design. It's resembles the stock 17" wheels without a center... and they're only $125 each!!

rolla guy 72, thanks for the breakdown.

Depending on which Tires you chose, it looks like the overall diameter is 29.1" or so for 235/70R16

This leads me to beleive that for those of us with 17" wheels, we should be safe with: 235/65r17 which is also 29.1" For an aggressive tire the options look kinda limited, but I may think about the Yokohama Geolander A/T-S for about $105. US at Tire Rack as my replacement tire. Pirellis Scorpions are about $150 each at that size!

Stock Diameter is 28" so the speedo error will be about 4% if I did the math right. Possible to have the dealer recalibrate?

Your math is about right for the difference in the tire circumference (3.9285714285714346% to be exact :p) but the options to recalibrate from the dealer are limited to a small selection of tires that are listed in Starscan.

My Commander is running tires that are about an inch bigger in diameter than stock, I have ran my Jeep through several of the "Your Speed Is" signs that we have around town and found that even at 45mph the speedometer seems to be still accurate (if accurate on the signs then its going to be the same for police radar guns and photo radar setups).

So the biggest size tire on a non-lifted Pat FD1 would be a 235/70/17 ???
Any experiences out there good or bad with going to a bigger tire.

I have not physically tried it yet, but hypothetically speaking, that size you speak of equates to a 30 inch tall tire with a max width of 9.3 inches.

If you compare that with an original 215/65/17 at 28" X 8.5" it would appear that you should not rub against the spring seat or strut. I may not purchase new rims and tires for a couple of months so I don't have any practical feedback at this time. However, if you look at page 1 of this thread, "jimmysjeepn" stated that he has 235/70s and no rubbing with 4 adults in the Patriot FDI.

Question: you put 2006 Rubicon wheels on there right? As the 2007 Rubicon wheels are a 5" bolt pattern and the 2006 Rubicon and earlier is 4.5" like our Patriots?
Forgive me if my research is faulty, but I think that's what I've been able to determine. I'm thinking of keeping my 16's on my Patriot and putting on 225/75's on there for a 1" lift. (overall, 2" diameter increase along with a 20mm increase in width)

sandtrucker5014

09-11-2007, 06:40 AM

I decided to keep my stock rims and I'm putting these 225/70-16 All Terrain T/A KO's tomorrow. It's going to run about $750 and will add 1" to the overall diameter and nearly an inch wider. I'll put different rims and tires on it when it can be lifted a couple of inches.

Hey hey, I put them on yesterday, and I'll snap some pics later today. They look SWEET! and they fit perfectly. It looks lifted higher, and it's around 8.6" clearance now. The noise isn't too bad, not as bad as I thought, and actually, the loudest they get is around 40mph, and on the freeway you don't hear them at all. I'm very happy, and now my jeep is more jeep like. Pics to follow.

I have a 07 Nissan Frontier King Cab and it's not being driven since I got the Jeep! It's a nice truck, but it's stiff and rides pretty rough, and is definitely not an off road machine, maybe simple dirt roads, but nothing that would lift one of the rear drive tires off the road or in loose stuff. That happens and you are done! So, I bought the truck cash, and I'm going to sell it real soon and put the money back into my savings. I love my Jeep! Just had to say that! I really do. Never thought I would like a 5 speed instead of auto, I grew up with manual transmissions in my cars, but it had been nearly 20 years since I had one. Now, I love shifting the Patriot. I can shift it sport style giving it lots of fuel, or take it easy on the rpms and just cruise shift it, the Jeep likes it either way huh. I have a '03 Nissan Altima with an auto if I ever want a day off from the Jeep, but so far, my Pat is my choice everyday.:banana:

No, they're perfect. Both turning and out in the rough stuff with a friend or two inside. I've already tested it, it's good. If you look at the bottom of the strut where the spring stops, you'll see that there is not a lot of room there, and with these I have an inch or less there I think? I'll have to check it out again, but figuring out the maximum size, that was a concern, so I'm not sure how much wider you could go. I basically went up two sizes. Here is a cool tire size calculator which shows you visually how your new size looks to your old one. I'm happy with the size I went to. Also, you have to know that acceleration and power is affected also. Going to a bigger size affects acceleration and you'll notice it. I think it's 4% with my size I went up to, and also with the new size, when the speedo says I'm going 60mph, I'm actually going 62.4mph a 4% error. Also, if you try to figure your mpg, you will think your mpg has gone down after the increase in tire size, but again, the 4% error has to be figured into your mileage, so if the speedo says I've traveled 280 miles, you need to in my case, multiply that by .04 or 4% to get true miles traveled, which would be 291.2 miles, then divide that by your gallons used.

225 is width of tyre, 70 is height of tyre sidewall and 16 is the wheel diameter :smiley_thumbs_up:

Sort of...

Actually 225 is width of tire in millimeters, 70 is aspect ratio (sidewall height divided by tire width) in percentage points, and 16 is diameter of tire in inches.

So for 225/70/16 the tire diameter would be (225/25.4)x(.70)x2 + 16 = 28.4 inches.

The 225/25.4 is to convert to inches, the multiply by .7 is to get the sidewall height and the multiply by two is because there are two sidewalls to cross over the entire diameter.

Also..You can have the dealer use the Starscan to readjust the tire size the car thinks it has so that the speedo and mileage figures will be correct.

Putting a larger tire on a car is the same as putting a higher gear ratio on the car, and you may see some MPG increase on the highway.

On the downside, lifting the Patriot (either with larger tires or a lift) also raises it's center of gravity, and lowers the force applied to the ground by the available torque, which means the car can roll over a little more easily and not climb quite as steep hills. However the percentage change is not much and is offset by the increase in ground clearance.

Sigh. Trade-offs, there are always trade-offs.

Good points. I noticed right away the difference in gear ratio related to acceleration, but now after a week or so, I don't notice it. It's funny, by just increasing overall diameter by 1.1 inches, it makes a discernible difference. Maybe not everyone wouldn't notice it. Right now, on this tank of fuel, I'm trying to get maximum fuel economy, so I'm not revving through gears, and trying to keep rpms down below 3 to 4k rpm. I just want to see at this very early stage (1000 miles) how the fuel economy will be. On the first tank, driving it with a healthy amount of gas pedal, it got about 23mpg. I know that as it gets broken in, it will get better and better, economy and power wise. The T/A KO :smiley_thumbs_up:radials have gotten a little quieter after a week, and they are hardly noticeable. Quiet on the freeway too. They are good tires for sure.

My new tires are roughly 28.5" overall diameter, and I wouldn't think you could go beyond 29" as the bottom of the strut is fairly close, so I would think, a 235/70-16" which would have an exact diameter of 29". Yes, they make T/A's like mine in that next size. That would also give you a lift of approx. 7/8" so over the standard FD1 Patriot 4x4 you would have 9" of clearance. Not bad, certainly better than lots of other SUV's

The bigger tires are nice for ground clearance. However it is not as nimble in first gear. But there are always trade offs. I would love to get an inch more from the suspension.

Got my studded winter tires yesterday.

Size is 235/65-17 and they're GoodYear UltraGrip 500 and I put them on the original 17" wheels.

Fit is perfect, less than an inch of clearance to the shock tower but no problems (since it moves when the tires does). Did a 4x4 episode on it out in the field and only rubbing I heard was when I did a full U-turn. So I repeated the process a few times (to be sure to leave marks) and took it back to the garage. Took out the front rims and with a hot air blower heated the front inner fenders a bit (they are plastic) and slightly pushed one corner in on both sides. And back to the field = no noises. Works like a charm.

So my point here is that on a non-lifted patriot - 235/65-17 is indeed THE biggest tire you can install without any real problems.

oh btw. Excellent Winter tires (we got our first snow today).

Those of you who have upgraded to a bigger tire, could you enlighten us? I too would like to go to a 235/70R-16 or 225/75R-16 for my FD1, do they fit in the rear well? if they don't fit, what tire should i use as a spare that would fit in the back well (and be a compatible match)? or would i have to just store a full size spare in an alternate way?

I had some Terra Trac MTs on my Disco. GREAT tire. Got them for NEW for $114 each shipped from a dealer on ebay. Nice, deep lugs, and mine were tapped for studs. Very quiet on the road. Ride nice too. Not the most agressive side lugs for a "mud tire", but hey - if you need that then some BFGs would probably suit you better. Great tire for the money though.

The Terra Trac A/W is nice too. 225/75-16s

Where are people finding bigger tires rub? I am doing the Rocky Road lift and want to put on 215/85/R16 tires... they are 3.1 inches bigger than my stock 205/70/16's. With the lift i should be OK height wise, my concern is turning when it will rub. Has anyone put anything close to this on? Any input would be helpful.

There's a fold in the plastic inner front fender, cabin side (meaning rear of the tire) in the lower middle part which rubbed a bit and also "the front bumper side" (meaning front of the tire) of the same inner fender tends to rub when you turn the wheels to the extreme right (on the driver's side) and left (on the passenger side).

I used a heat blower to warm up the plastic a bit on the 'fold' (you'll see what I mean when u look at it) and turned it in a bit, the front of the tire rub was fixed by fastening the plastic fender to the frame a bit higher up.

I'm not sure how the lift kit operates, but the thing that's stopping me from putting on any larger tires is the shock absorber tower, which is VERY close to the tire with 235/65-17's (good thing that it moves up and down with the tire so even though it limits the size, close isn't a problem.). I would also guess that the front of the tire rub might not apply in your case, since the body sits higher up compared to the tire...?

I think i have decided on the Toyo Open Country AT's in a 225/75/R16. Waiting for UPS to find my lift or Rocky Road to send me another one. Soon as i get it i'll install, go pick up the new tires and get it all aligned in one shot.

I gotta thank AV, I have cruised the lots and even rented a 08 Pat to try and figure out max tire size. I had figured 235/65/17 was about it and you confirmed my thought. Thanks for bolting them up and fill us all in. To bad BFG All-Terains don't come in that size yet. They have to be the best all around tread ever.

Hey hey, I put them on yesterday, and I'll snap some pics later today. They look SWEET! and they fit perfectly. It looks lifted higher, and it's around 8.6" clearance now. The noise isn't too bad, not as bad as I thought, and actually, the loudest they get is around 40mph, and on the freeway you don't hear them at all. I'm very happy, and now my jeep is more jeep like. Pics to follow.

Sandtrucker Please confirm : Your Pat is stock? no lift? No rubbing at all with 225 / 70 / R16 ???
If so I'll keep mine (Santa Fe with Cooper Discoverer winter tires) to put on the Pat next winter.
Waiting for your expertise and experience.

I went with those BFG A/T's in a 225/75R16 with the RR 2" lift and i get rubbing when i turn really tight.

I read every post on this thread and am in a bit of a dilema...

I'm going to buy a Patriot 4x4 FD1, and have found the rims I want to put on. I have no intention of doing a lift.

The rims I'm going to get are 16x8, offset +10. Stock rims are +39 offset I believe.

I have figured out the ideal (overall diameter 28") tire size is 235/65/16. However they don't make any treads I like in that size. So I'm leaning toward a 235/60/16 tire. This reduces the overall diameter to only 27". Any thoughts?

I was also wondering if anyone on here was running an 8" (or more) wide rim with 255 series (255/?/?) tires at stock ride height? My concern about fitting a 255 is the back spacing. Using the tire calculator that series is slightly wider than stock.

Playbak,
I'm going to run a 29" tire on a set of Rubicon wheels. This should not be a problem with rubbing. I don't mind minor rubbing, as long as it is in an unfinished area(not painted). There are some others that have done this and have reported no interference on painted surfaces. I'm gonna try for myself and will report back. My wheels should be here this week..............................BTW, it will be on a non-lifted Patriot. I'm considering cancelling my order with RR. They said it would be shipped by now. I have not heard anything from them and will consider making my own lift for the front. There is some good "tech" on the L.O.S.T.JK's site for doing just that.

P.S. The old saying that every Jeep is differant has some merit. Each tire has subtle differances also, and may produce differant results.....ie, BFG KO's have a large shoulder block in comparison to others, and may produce rubbing on the inner fenderwells(plastic).
quiff69's tire should be a 29.3" as a 225/75 and in comparison a 225/70 is a 28.5", this may make the differance in what is considered a problem. Remember, tread width is also a big factor and BFG does not list that dimension specificly only section width, here is some data on that tire anyway.The underlined is what I think quiff69 is running.The BOLD and the ITALICS are the ones I am considering. ("C" range will ride a little softer) Just thinking over the section width change on a 8" wheel with consideration to backspacing vs.strut clearance.

Good to know Hvac thanks for the listings. Back spacing is definitely my major concern for choosing the tire size. I won't be getting a size that exceeds 28" in overall diameter.

So that means I have to consider "section width"?
I take it that is the width of the tire on the rim?

If no one on this board has run a 255/?/? series tire then I doubt I'll be the first to try lol.

hvac59

01-15-2008, 11:16 PM

Yes,
Cross section is a factor, and it is influanced by the rim width. General Grabber AT2 is sold in a 255, the diameter is acceptable, but the section width and traed width is a little steep! My bet is that it would interfere with the strut assembly. At least in any rim that we would want to run on our Patriots. The Rubicon rims (8") that I am interested in have a 5" back spacing. I wan't to measure the factory Patriot backspacing for myself to be sure, the popular belief is 4.7" !!!! Anyway, I'll post back with that dimension because I've not read of anyone measuring it first hand.

I was able to find an offset calculator that really helped:

http://marksink.com/tire_wheel_offset/offset.html

Another problem I realized after calculating is potential rubbing in the wheel well under sharp turning. I found out that the 8" rims I want extend 1.9" (48mm) out. That's great news for the back spacing though which actually increases a little (10mm)

After making a number of calculations I'm going to forget about a 255 series tire and go with a 235 to be safe. I just have to decide whether to go with a 235/65/16 or a 235/60/16. The later has some nice tire options and has less risk on rubbing.

I'll be talking to wheel sales next week and post what they recommend.

By getting the 17 Inch Wheels, Does it raise the Ground Clearance at all?

playbak

01-17-2008, 12:42 PM

It all depends on the tire size.
Most of the time it won't because you'll have to compensate a larger rim with a lower profile tire.
This thread has discussed almost all tire size options available on a patriot for 16" and 17" rims.

What is the method for keeping the speedometer/odometer accurate when changing tire size on a Patriot? In my day we switched out the gear in the tranny or transfer case. Is this a re-program at the dealer thing or can I do it my self? I'd like to buy bigger tires with a taller sidewall and white letters. More traditional SUV type stuff.

What is the bolt pattern on the patriot? There are five lugs, but how big is the circle.

My speedometer is correct now and I want it to stay exactly correct. Not a little off one way or another.

dokboy

03-09-2008, 05:53 PM

I am 99% sure on this one, you will need to have the computer flashed to compensate for any change in outer tire diameter. Sorry I read it in here once but can't for sure remember the bolt pattern, I think it's 5x5. There is a thread that contains that info.

i got the 235/60/R17 Toyo Open Country and I was told these were pretty much the highest I could go....but found out the you can probably push it to 235/65/R17 for those of us with 17 " rims....none the less, I like the more rugid tires :)

Howdy Folks,
I've been seriously perplexed by the issue of restricted tire availability, especially for Trail-Rated Patriots. I want to get the most out of my vehicle and need a more aggressive tire; however, I'm not interested in lift-kits, in purchasing different rims, nor do I want to throw off or re-calibrate the computer, speedometer, etc. Having searched the web and spent time with experts I've concluded there is nothing available for the odd 215/65/R17 size beyond the stock Wrangler SR•A that comes stock with a trail-rated Patriot. It is odd that Jeep would not have considered this.

In getting the input of tire experts and from a Jeep dealer, I have found a possible solution. This is to slightly alter the stock size whilst preserving the rolling radius. Switching to a tire size of 225/60/R17 makes available the Geolander A/T•S. This tire has good reviews and seems somewhere in between the Toyo Open Country and Michelin Cross-Terrain in terms of tread performance. The size will not require any re-calibration, should not alter end-to-end clearance on tight turns and have no impact on Jeep's warranty, safety ratings, etc.

I have had the current tires "syped" for an immediate remedy until they run down. I'll let people know how this alters performance in the meantime.
Thanks for all the great input! Best regards,

if you're sticking with your 17"'s, i would recommend the Firestone Destination A/T's......they got a great review on 'tirerack.com's site and they look GREAT!

if you go back to the 16"s like i did, you can get the BFG Mud Terrains in a 225/75R16. :)

Be careful with tires that are too big on the patriot. I had to pull off my 255/65/16s because I nearly had a really bad accident the other morning.

There was no rubbing, only a very slight rub when reversing in full lock... except, the other day I had to hard break at about 20 mph and car spun out control as the wheel well did all the breaking and nearly popped the tire. It was freakin scary and did not sound or feel good at all.

I would not go taller than 28" or wider than 10".. which on my 16" rim leave me very limited options since nobody seems to make 255/60/16 or 245/65/16

Personally I like the look of wider rather than taller tire.

I'm now using 235/60/16.. which is about 27 x 9.25.. I had to make a quick decision since PepBoys was gracious enough to replace them for me after 2 months.. wow. Anyways, I'm not happy with size. But I just being stupid and neurotic about it.

Those Firestones you mention look great but I can't get the size...typical of the problem. That's a scary story above and sage warning.

Dr. D. and grg_georgiou, could I get a pic of your patriot. I was thinking of getting 225/65/17 or 235/60/17. Also Dr. D. with 225/60/17, according to 1010tires.com, the tires would be 1.373% faster than the speedometer. Would recalibration be required or is recalibration required when the percentage diff is greater than 2% or 3%?

Thanks all for their input.

Hi guys,

This is a great thread, tons of good information. I will be lifting my MK soon (RR 2.125") and I've narrowed down my tire options after reading all your contributions.

I'll keep my 17" Pat's wheels, they LOOK good (may be better if I paint black center of the spokes?) - not sure if they are good, compare to other Jeep wheels, as this is my first 4X4. Comment on wheels anyone?

No BFG' - there just is no suitable size for 17" rims, too bad. Just like there are no more aggressive M/T tires for 17x7 rims that would fit Patriot small wheel wells.

Firestone Destination A/T 235/65R17 - 29.1" 716 RPM 103T 103.77/100M
Yokohama Geolander A/T-S 225/70R17 - 29.6" 701 RPM 108T 105.99/100M
Firestone Destination A/T 235/70R17 - 30" 692 RPM 103S 107.37/100M
Yokohama Geolander A/T-S 235/70R17 - 30.3" 686 RPM 108S 108.30/100M

Is anyone driving on any of these tires on lifted Pat? What are the pros and cons of 235 vs 225 width? Would 225 be better for this light vehicle?

With lift I do not expect any tire rubbing with any of these, but a heat molding inside wheel wells will solve that problem. Thanks for that tip!

Loss of power with larger tires is not welcome, but I do not think it will affect rest of the drive train, after all it is CVT2 FDII, it will compensate (with MPG drop in city no doubt!) So my final ratio will be down effectively to 18:1 or so... Extra clearance - up to 11.3" - will be great, it is a must on our deactivated west coast logging roads.

No one confirmed speedometer actually can be accurately adjusted to any of these sizes - I was told the limit in software is actually 28" tire - but I love to hear if someone has better result calibrating it, and how. Anyway, I could live with up to 8% error. It will be lesser of negative trade offs. I any case, how much does it cost to have speedo calibrated? Anyone?

Be careful with tires that are too big on the patriot. I had to pull off my 255/65/16s because I nearly had a really bad accident the other morning.

Tire size calculator says the diameter for those is only 29.1", so that does sound surprising. Could it be that it was the width that caused the problem and not the diameter of the tires? Others have changed about 29" tall tires under their vehicles - anyone else experienced trouble in hard brakings?

Yokohama Geolander A/T-S 225/70R17 - 29.6" 701 RPM 108T 105.99/100M
Firestone Destination A/T 235/70R17 - 30" 692 RPM 103S 107.37/100M
Yokohama Geolander A/T-S 235/70R17 - 30.3" 686 RPM 108S 108.30/100M

I don't think any of these will fit without modifications. The tallest tire that fits would be somewhere between 29" to 29.5". It's that "shelf" for the spring at the front that limits how tall a tire can be.

That's a great looking tire!

The tire thing is crazy with these vehicles...it's ridiculous Jeep would put stock tires on a supposedly Trail Rated vehicle without considering decent tires. The only options for are stock fit with 215/65/17 are little car tires. I've actually had some Jeep people tell me the vehicle isn't intended for anything but pavement so the fact that only car tires are available is reasonable (of course they don't say stuff like that when trying to make a sale). I defy this! Having done some pretty big winter driving, high berms, deep gravel beds, steep hills and creek crossing, it's obvious these vehicles need to optimize all the have which means a good tire with aggressive tread is critical. But of course, as we know, Jeep designed it so the only spec fit spec on a FDII Patriot are wimpy little care tires. The closest aggressive tread tire is the Geolander A/T-S but requires a slight alteration in size which some Jeep people say will void the warrantee.

I've got a Jeep guy who seems to think a slight altering should be ok. We measured and at full lock there's about an inch. Therefore, I think 225/65/17 is about as big as it could go and remain safe. This makes the tire one inch larger and slightly alters the calibration but should be well within safety. The Geolander A/T-S in 225/65/17 should make a big difference for this winter and the summer to come...that's what I'll be getting unless anyone else has a better idea.

Congrats on the great looking tires!!

Slight rubbing problem... if you look to the right of where my tire says FIRESTONE, in the section parralel to the letters F and I, there is a one inch wide vertical strip of plastic well liner that makes contact with outer most edge of tread. The rubbing is only limited to locking left and right. No problems reversing or fast stops (55mph). There does not appear to be any metal to rubber contact. Just rubber to liner. Thanks for the compliment King.

For those of us "stuck" with the 17" wheels we bought, it's a good discussion for what to throw on after our stock SR-A's wear out. I suppose I could have spent the $590 on aftermarket wheels, but of course that includes new tires, unless you want to keep those stock 205/??R16's till you need new rubber. No thanks. So I guess it's a compromise to have (IMO) the better looking 17" wheels and a limited selection of 2xx/xxR17 rubber, especially without a lift or liner mods for rubbing.

Lots of great looking Patriots with new wheels and/or rubber though! I'm jealous.

I'm thinking about going for the Geolander in that size as well. I thought about going to 215/60 or 225/60, but I really don't want to lose any sidewall, not with aluminum wheels and the potholes we have here.
According to this: http://www.miata.net/garage/tirecalc.html Going to that size will only change the diameter by 1/2". So, it shouldn't be that big of a deal, right?
My only other question, is are the Geolanders a tire I can get a lot of mileage out of them? Are they still good on-road?

http://www.jeeppatriot.com/forum/pic...pictureid=5169

as you see, they only rub in the front wheels.

Although it rub at full lock, I recommend this tires. They feel great, you won’t even notice street holes compared with the continental/goodyear’s one, getting over sidewalks would be easier and the riding comfort is a new level experience.

im planning to get the stu coils!

Super like.
