Treadwear Rating

[Octomonkey]

Is the treadwear rating on tires an industry standard, or is it something that differs amongst all the companies?

Treadwear rating is set buy the company that manufactures the tire. It also is different when moving to a different performance class. Such as, High performance, Ultra high performance, touring, LT, etc.....they have their own ratings per manufacturer.

What classifies the standard tire?

[05Judge]

Basically the companies use a candidate tire and drive it against their product tire....The candidate tire has a grade of 100.....so basically whatever treadware grade you look at when buying, say its 220. Then that tire should last 220% longer than that companies candidate tire for that class.

It's all basically a marketing scheme now. What exactly are you looking for anyways? I personally wouldn't hold a candle to the wind in hopes of getting anything out of the treadwear grade.

I was just curious. I have BFG G Force Sports on my car with a 340 rating. My dad has Sumitomo HTR on his Mustang with a 160. My next set of tires I want to get are the Bridgestone Potenza RE-01R with a rating of 140. I just happened to see the Sumitomo rating this evening and thought that was a really low number for the tire, especially compared to the tires I'm planning to get.

FWIW I've gotten 15k of HARD driving out of my RE-01R and I can easily get another 5-10k out of them if I drove nice...but I won't :)

That is great news! How do they perform?

I used to be Manager of Tire Sales for Bridgestone/Firestone. I have seen many of their Ultra high performance tires get almost 40k.....It doesn't happen much but it can. I would say you would probably be looking at somewhere between 20k-30k in reality....

Most Z rated tires, even the W, Y speed rated tires, last about the same amout of miles.

I'm used to buying the higher performance tires, so those numbers are no problem to me at all.

Yay! I can't wait. I hadn't really read a whole lot of reviews on them, but you just sold me. :)

I have some Yokohama ES100 for street driving. Treadware 280. The way I drive the rear tires lasted about 12K miles. Probably could have manages 2-3 times that if I drove like a normal person. I just bought some Yokohama A048 R Compounds for track and Auto-X use. Got so addicted to the traction (treadware 60 medium-hard compound) I left them on for a week.

So in my experience, treadware is relative to the way you drive.
