Benefit from wider & taller tire?

paokarathodoros · Aug 21, 2014

I am considering to replace the OEM 215/60/17 tires with 225/65/17

A) Apart from better appearance is there any other benefit?

B) I also think you get about 1 cm (=about 1/3 of inch) higher ground clearance but I believe it is almost unnoticable

Which were the reasons that made you go to larger tires?? (apart from those who have lifted the patriots)

On the down side with wider tires you loose acceleration, AND most importantly it is as if we have LESS TORQUE???? (an area where patriot suffers): (so in sum larger tires alone are negative especially offroading?)

and your speedo will be wrong

So are there any practical benefits or just looks?

more surface area, better traction.
but remember better traction at low speeds on dirt/gravel and such,
at higher speeds and wet surface depending on treads, can be more prone to hydroplaning

More tire choices. The largest OEM size is 215/65/17 = 28" so going to 225/65/17 = 28.5" isn't much of a difference. The overall diameter variance is 1.83%.

Depending on the tire, you can get a better ride quality out of it. More sidewall = more sidewall flex = more comfortable ride over harsh surfaces/road imperfections.

More/different tire choices. It does also look better. Its amazing what even a small tire size increase does for the look of a patriot. (at least in my eyes) the 225/65-17 should be the stock size for a FDII patriot.

I just upsized to a 225/65/17 and, aside from looking a lot better, I have noticed a better ride quality. Cracks, potholes, bumps, etc in the road don't feel as rough.

paokarathodoros · Aug 22, 2014

for my FDI 4X4 limited patriot the standard tires are 215/60/17

using the very handy tire calculator you suggested going to 225/65/17 ( a size that I see many have used without having lifted the patriot)

Gives a 5% difference (outside the 3% variance limit) almost 1,5 inc higher g clearance

215/60R17
Overall Diameter: 27.16 in 689.80 mm

25/65R17 Imperial Metric
Overall Diameter: 28.52 in 724.30 mm

Diameter Variance: 5.00%

Do u think it is safe??

aroundincircles · Aug 22, 2014

i used to run 245/65-17 tires (lifted with spacers) no reassson they would be un safe. a stock tire size is 215/65-17 which is a 28" tire or .5" smaller than a 225/65-17. which is minimal.

paokarathodoros · Aug 22, 2014

If I go to the 225/65/17 (28.52 in)

When changing to the bigger tires Do I have to do any modifications/ tweeks to the suspension, alignment/brakes etc?? Or

Mine is a FDI 4X 4 (with oem 215/60/17 27.16 in)

I guess there in the States the standard even for FD I is 215/65/17

No additional modifications needed. Just remember that your speedometer/odometer will be off by 5%. I've been running 225/70/16 which are 28.4" tires for 20K+ miles now with no issues what so ever. Thinking going with 235/70/16 = 29" next time.

Since the odometer will be off ( you travel further on each revolution with bigger tires) is it legal? The mileage shown on the odometer will be understated.

It's only illegal if you get caught!

Bring it to a dealer. They will charge you $120 to reprogram it and you can keep your 100k mi warranty. Just did mine the other day: http://www.jeeppatriot.com/forum/showpost.php?p=1106713&postcount=55

Typically we can only reprogram for stock tire sizes. Jeeps may be different than other Chrysler product though. They charged you too much too. I would only charge 1/2 hour to reprogram tire size.

the_jeep_now · Aug 22, 2014

The dealer can only reprogram to the largest OE size of 215/65/17 which is 28". So if your tires are larger than 28", your speedo will still be off. No point paying $100.

rcguymike · Aug 22, 2014

They just match the closest diameter setting... They had it for an hour and a half. Idk why... Should have took them 15 minutes max... Even with looking up info on a tire calculator. I kept my tire choices under 28". Mine are 27.7" and I think they went with the size lower. I would have forgone it but $120 is worth keeping my warranty.

Tires would have no effect on warranty. I install 4" lift kits on brand new rams with 35's all the time. These are unsold trucks on the lot.

I've read that quite often and the service manager at my local dealer agreed - but I had them change it on mine regardless because mine came stock with 205/60/r16's so a significant difference between the 225/75/r16's I mounted. But when the mechanic came back he said he could set it to most any size available and got it almost right on (my speedo reads 59km/h when travelling at 60), it wasn't a matter of setting the tire size, but the pinion factor, which he could set to any whole number. Perhaps they sent different programming for Canadian Patriots or early in production (mine's an '07) but that's my experience.

If you change tire sizes without reprogramming the computer your odometer will be off which will void a power train warranty if they happen to notice.

Benefit from wider & taller tire?
