I concur...

 

... tire siping works.

 

Years ago I pit crewed with a URC Sprint Car team and we used to add sipes to the sprint cars rear tires when the dirt tracks were wetter then normal. They can definitely work to improve traction, but if the track dried up and hardened we'd often find whole tread blocks ripped off the tire after the race.

Let us know if they are working better for you though with added sipes. Can you post some pictures too Earthworm?

 

The Sipes are Razor Thin about 1/4" apart from each other and start from the center of the Tire and end before the outside Tread Block. You can hardly see them unless you get real close to the Tire. Girlfriend still has my Camera maybe I can get some Photos, may not be able to see the sipes very good though.

 

siping is good for traction, bad for tire life. Pretty sure that's the end of the discussion.

 

Well, All I can say is I've never heard anyone say "Damn! That ruined my tires! I wish I'd never done it."

Not exactly a ringing endorsement, but seriously, I've never heard anything bad about doing it to a regular use passenger vehicle. It seemed to have been way more popular in the early days of radial tires. I haven't heard much about it in years, until now.

Let us know what you think after driving on them for a while.

Remember the old Goodyear Vector? Wasn't that almost like a factory sipe? My dad put 80,000 miles on some of those and they are still on one of our trailers.

 

Siping is illeagal in UK/Europe ....It causes the manufacturers tread blocks to move all over the place & lead to dangerous handling. & overhating....Way too complicated & scientific for the layman./ tyre fitter , to mess about with.

 

Thanks for sharing, valuable information. Have a nice day or evening.

 

wow I have never heard anyone say that siping caused dangerous handling, and it is supposed to reduce the heat on the tire. I have heard people complain about the tire chunking, but that's the only complain I've ever heard.

I don't have any data to point to so it could just be one of those hold overs that really hurts rather then helps, like leaving your tailgate down to improve fuel economy but of the people I know who've paid to have it done, nobody has ever complained that the handling is worse.

 

I've seen how those people across the pond drive!

 

 

Thank you Todde for posting the Video. I did alot of research and had heard about tire siping and grooving for years but never had it done to any Vehicle that I've owned until now. Just put it on here for something to discuss. Thanks again for the excellent Video.

 

To me, tires are probably the most precious parts of the vehicle to maintain. I would NEVER modify tires. Your life (and others') depends on these things. I've dealt with too many accidents due to a tire blowout that resulted in serious injuries or death. I'd much rather run on tires with good treads than do aftermarket siping.

 

Brand New Tires with a little extra Siping. Once again, BRAND NEW TIRES!!!! With Woodpecker common sense that you are using, these Tires are not May-pops. The siping is on the middle tread of a brand new Tire not the sidewall, people have been doing it for years. I guess you guys didn't look at the Video Todde Posted cause if you did and still have this mindset then it's kinda like this, I don't mind cause you don't matter.:doh::doh::doh::doh::doh: SIPE THOSE TIRES FELLOWS.

 

Thanks for a little common sense kds ---ask yourself why this practice is illegal in Europe ???

 

Because......... You have an oppressive government due to your lack of guns?

 

Worm, re-read your first post



then when someone gives you their opinion (which you asked for) you abuse them saying 'i don't mind cos you don't matter'......go figure

open your mind

 

The winter tires for the Avalanche started out as new, AT/MT tires, siped and studded. The siping process generates hundreds of additional grip edges in the contact patch.

The winter tires I purchased for the Patriot, Continental Extreme Winter Contact, have a stock tread pattern that is a siped tire.

The Grabber HTS that is currently on the AV looks to be siped from the factory...

It works. Get over it.

(Concerning gun ownership, I live in Kalifornia and have a CA CCW (good for the entire Republic of Kalifornia) issued by the Lassen County Sheriff's Department. I also have one issued by the State of Nevada. In GLOCK I trust.)

 

kds the siping was done by a professional Tire Shop that has been doing it for years. There are People that groove and sipe Tires themselves. This was not a DIY project. The Tire has to meet tread depth requirements or Les Schwab Tires will not sipe them. In my case the Tires were new Tires. Les Schwab has a machine the cost thousands of dollars. They know what they are doing. The sidewall on the tire is not going to blow out as there was nothing done to it. The sipes are on the middle tread of the tire about 1/4" deep maybe more. Thank you for your input and in your case do not sipe your Tires. Did you watch the Video Todde posted ? Too harsh, maybe and maybe not.

 

And tire shops never do any questionable practices, like selling questionable tires? *gasp*

Why would I trust a video on YouTube that claims to be a "scientific" "study" from a website that clearly has a bias towards siping? That video -- and the test subjects in it -- have too much human control in it for me to trust it. It's nothing more than a sales gimmick. You may think that siping helps traction on wet or snow-packed roads, but it's actually shown to increase stopping distance on dry pavement. Why would that be a good thing when a majority of our driving is on dry pavement? Tiptronic is right... why is siping illegal overseas?

One last thought for you... I hesitate to mention this because this one bothers me and I don't like sharing these stories with strangers, but maybe it will help you see where I'm coming from. I handled a collision a few months ago where four people were in a vehicle. The driver was the daughter of our insured. In the front passenger's seat was our insured, an elderly gentleman. In the back seat was our insured's wife, and sitting next to her was her grand daughter, a 6-month infant in a car seat. As they were on a highway overpass, they had a catastrophic tire failure, causing the driver to lose control and cross three lanes of traffic to the left and hit the concrete barrier. In an attempt to regain control, the driver overcorrected and crossed the same three lanes of traffic and hit the right concrete barrier. A second vehicle then rear-ended the first vehicle, ejecting the elderly gentleman in the front passengers seat and the infant in the rear. Both landed on the road beneath the overpass they were on. The infant survived, the gentleman did not. The cause of accident? The catastrophic tire failure. Not because they were bald... not because they were poorly maintained, but the highway patrol determined that the tires were "intentionally modified beyond the manufacturer's specifications."

In your first post you stated "I can't leave things alone on a Jeep not even the Tires." So you're doing this just because you can't leave things be? Sounds about right, but it's not a very good reason. It's clear that you offered this up for discussion, but won't consider the ramifications of such a practice just because people who offer differing viewpoints don't matter to you. Let us know later on down the road how your tire treads are doing after siping.

 

Thank You for the info and may God Bless You.

 

Personally, I wouldn't modify any tire. I won't buy retreads either.

 

ya i agree. I can see both sides on this subject. When someone posted factory siped tires, it made me think that maybe there is a reason tires are not siped from factory. Maybe they know something we dont. Or maybe tires work best in their tests and do not need to be siped. But it is a cool technique. I am getting ready to buy some Hankook ATM's that are so awesome lookin. I think I am going to get the 225/75/16's. I will post pics this weekend. Thats after the lift also.

 

Les Schwab Tires siped my Tires, they opened in 1952 and are in 8 Western States with over 400 Stores. For what it's worth!!

 

im going with an all weather tire. i hear they last longer and you dont need to worry about getting new tires come spring.

 

well im buying AT's because they are rated great in snow and winter and wet driving. The people who also reviewed this said the same. I also hear that AT wheels last longer. They happen to be great looking cosmetically so I am going with the Hankook ATM's.

 

:doh::doh:

 

I have considered siping. If you talk to the people at Les Schwab, siping is the best thing since sliced bread. They claim pretty much everything is improved. I am still on the fence about it. My question is this: If it's so great, why don't they come siped from the factory?

 

Depends on the Tire, some knarly tires don't have any siping and others have a lot of factory siping. I just wanted more siping on my tires is why I did it. Stay on the fence and don't sipe your tires. I'm one who can't leave things as they are so siping the tires is what it is.

 

For those with aftermarket Tires that don't have much Siping, get em Siped and hope they don't blow. I think some People are just overly PARANOID, my two cents worth or not worth opinion.

 

I sipe my M1 oil. It is too slick to stick to the bearings and cylinder walls if I don't.

 

That's some damn slick oil, OMG !!!!!!!!!!!!!!!!!!!

 

Who needs STP??? Not me!

Git-R-Done! ;-)
