cant find the treadwear for my tires!!!
 

like so...ive searched for so long and cant find the tread wear for my freeking tires anywhere. i have dunlop lm (leman) 701 and toyo proxes f-08's. if anyone can get me the tread wear on these tires...that would be awesome.

The sidewall might have the rating on it.

-Max

absolutely nothing....

No "UTQG" or "280AA" stuff anywhere?

I thought that they must legally have the traction and temp ratings on the tire -- not based on any real knowledge to confirm that -- it just seems weird that they still put it on most tires when I can't recall ever seeing anything but AA. Perhaps the "AA" rating has some marketing benefits and thus they keep putting it on there even though there is no law. Or maybe some countries have laws and others don't, so tires that are sold internationally have it and regional tires don't.

I could be wrong, but those tires are not legally sold here -- they are not DOT approved.

they are tires that were on wheels i got from japan. i just went out to double check the tires again. both of them, absolutely nothing on treadwear, traction, or temp rating.

Like I said, they are not DOT-approved and do not have to carry that information. Why do you need to know the treadwear so bad? They are just relative numbers within a manufacturer's line and don't have all that much real world use.

WRONG......the tread for performance entthusist lets you know how long the compound will last given the gov. rating. Most Race tires have an extremely low TWR. The lower the stickier and usually the softer compound. R. Race tires have a TWR @ 60 Dot drags I dont know. My street tire is 160 and when heated up in a burn out i got a 1.789 60 on 18X40's.
eben the expensive Goodyear have TWR in the 280 range,.( because the public wont buy tires every three months.

WRONG. There is NO government rating for treadwear. The treadwear ratings are purely relative ratings for each manufacturer to some internal standard. A tire from company A with a treadwear rating of 200 will theoretically last twice as long as another tire from company A with a rating of 100. However, the lifetime of a tire produced by company B with a rating of 200 may have little to do with the same-rated tire by company A.

rynberb's right; it's a bunch of hooie. There's much more to tire grip and wear than what the traction and treadwear ratings are. Just like there's more to motor oil than the 15W-30 on the bottle.

I took a look at my Hoosier AS03's when changing them Sunday and they have a traction rating of "C" (the lowest) on the sidewall. Did you realize that's because all of the traction ratings are in fact done in the wet and NOT in the dry? Even a tire with an "AA" rating doesn't tell you anything about what it does on dry pavement because they are not tested that way! The mileage rating is at best a wish as well. They don't even run the tire until it's worn, they run it a short time and then extrapolate the data waaaaaaay out there. Read up:

WTF from Damons link:
T
he U.S. Department of Transportation (DOT) National Highway Traffic Safety Administration's (NHTSA) Uniform Tire Quality Grade Standards (UTQG) were originated to provide consumers with useful information to help them purchase tires based on their relative treadwear, traction and temperature capabilities.

Thats gov....

2nd:
The tire manufacturers then assign a Treadwear Grade based on the observed wear rates. The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.

look at my thread I said usually...
I do road race and Dramon's C have nothing to do with treadwear but compound softness. My old RE71 R (race)were stamped TWR of 60. I have had all but Goodyear....but thats off the comment.Dramons UTQ are 40(TWR) C A

What I did not know:
Typically, comparing the Treadwear Grades of tire lines within a single brand is somewhat helpful, while attempting to compare the grades between different brands is not as helpful.
And yes new carbon copounds today make a difference in the traction to wear usage.I will say over the last 20 years I have purchased street and race tires. IMy personal experience is to fined the lowest treadwaer performance tire...its save money and gives you what you want. Mark57 had the top of the line Potenza and is now on a less expensive brand. Broke his diff the first time at the track cause the new softer tire staleed his car evrey time.Potenza never heated up during the drags or hot laps.
My own experience
