Edit: See post 8 below regarding delay in 200 tread-wear limit rule for In Street and Street Touring

Toyo announces 200 TW R1R (they were 140 TW):

This whole treadwear thing is a bit of a disgrace. The ratings clearly don't mean anything. All it's done is hurt people who bought tires based on what they expected to be legal going forward. Now that all the 140's have been re-stamped, anyone who bought 'real' 200's are stuck. There's no way a R1R compares to a Rival, RS3, or ZII. It's not exactly cheap either, so the tire costs haven't changed much at all, and the life hasn't improved.

I might as well just buy some Hoosiers and write '200' on them with a marker.

Since the ratings are supposed to be a DOT standard, I'm surprised they haven't gotten involved.

That's interesting. I only can speak from what I've read for S2000's, but autocross guys love the ZII star specs and the RS3 for hotter environments. R1R's seem to suffer from poor longevity while offering similar grip levels.

As far as DOT intervention, it's likely such a small volume issue that they don't have a reason to address it. Manufacturers are apparently allowed to advertise a treadwear number lower than what they test, but not the other way around. For Hankook, Toyo, etc.. it looks like they're just stamping the numbers higher, to a value more reflective of what the tire should have been.

I agree though, it's pretty ridiculous how its working out. Luckily it doesn't affect us much either way!

...and folks though trying to get away from R comps was going to be easy.


Its worse!

Does this mean that existing R1Rs stamped as "140" will be accepted in the Street Touring Category?

Changed title to better point out the rule change.

I just shake my head at stuff like this. Aside from this season with the "R" classes, I'm perpetually in the "show up, go fast, pax last" class.
