Ideal would be 265-295/30-19 but not available in RE71s.

I've written off Cup2s (too expensive/wear fast) and, from what's left, I have narrowed my choices to:

RE71Rs in 255-285/30-19, or
Yoko AD08 in 255/35-19 and 295/30-19

I run stock suspension with camber plates -2.8 front and -1.8 rear. I'm beginner/intermediate level and run on dry only. I would be ok sacrificing a little grip for symmetrical pattern and longer durability.

I haven't found much here, or on the F80/F82 forum, about the AD08s. Any feedback from people tracking these? If dry grip over a 30min session on RE71R is a 10, where do AD08s rank?

I have been pretty happy with the slight oversteer on the 255/275 RE71 setup and would expect more neutral or slight understeer in 255/285. Would the 255 to 295 difference in the AD08s move the car much more noticeably to understeer?



Did you run them? What did you think of them?
You can always run a 305/30 19 in the rear with the RE-71R. Though the RE-71RS with a totally new tread pattern is phasing out the Re-71R and you won't be able to get a 305/30 19 in the future unless BS expand their size range.

You can now run a 265/30 19 or a 275/30 19 square with the RE-71RS.

My issue with the RE-71R on the track is not the short tread life but more that the grip comes down after a few heat cycles where as the AD08R's grip is more consistent throughout albeit pound for pound, quite a bit lower than the RE-71R when both are at their peak.

Sometime to read about the RE-71R here
