Yes I seen lots of them at track days, people like them, surprising Michelin hasn't upgraded them somehow. Strange to say but they just 'seem' blaa to me... have no idea why I never tried them.

On a different note, does anyone know anything from experience, or even heresay about the B F Goodrich g-Force R1? Info > http://www.bfgoodrichtires.com/overv...e-r1/3824.html

Hadn't followed the brand much, but gather the last effort was not so good? Unsure. But this may be better? Certainly a 40wr makes it a +10 group rated. Does a 40wr almost automatically mean it's only good for a few sessions (day or two)? Or even in this +10 grouping longevity still can vary quite a lot?

 

spoke too soon - of course http://www.tirerack.com/tires/tests/...irePageLocQty= so wear is the only question left with these

 

GrassRoots Motorsports had a recent issue testing most of the DOT R tires mentioned in this thread, including the R1.

 

While it will vary from tire to tire, you can bet that a 40 treadwear semi-slick molded at 4/32" (like the R1, V710, A6, and R6) is not going to last as long as a 100 treadwear, grooved tire molded at 6/32".

Unless you're doing some kind of competition event where every last tenth matters, I just can't see pissing away an extra $300+ per set on tires that aren't going to last as long.

Personally, I'd suggest something like an R888 or NT01 as a good compromise between grip and longevity. Heck, if I could have gotten R888s for the same price as AIM Tire when I bought my RA-1s, I probably would have opted for R888s instead.
