Kumho PS91

Don't forget the S-04 Bridgestones. To me, this is the perfect DD tire. Still works pretty well in the cold. Dry and wet traction is VERY good! Quiet too. Price is very reasonable.

After trying Nitti Invo and Hankook ventus, I've had the most satisfaction from my S04s and will buy again. Unless I sack up for Pss

I just did my 2nd track day, first time with Michelin as3 and this time with s-04, Very happy with this tire. I still had track left to use on turn exit so now I'm not going fast enough for the new tires. Last time felt like a greasy bar of soap on the road. Would definitely buy s-04 again as a dual duty mostly street tire. I'll keep an eye on these kumho though as I've read kumho has put a lot of money into their r&d recently to start making some pretty competitive tires. My friend just bough some of their v720 tires that came in a very close 2nd place vs the 71r and they were dirt cheap comparatively.

I had the opposite experience. Never tracked but drive like i stole it on the streets. Had the AS3 and it hooked well from a dig all the way until hitting the wear bar. Swapped to the s-04 and instantly noticed the traction dropped (reminded me of ventus evo). The tire size of the s-o4 also measure smaller compared to other brands with same size. Looked kinda goofy and off on my stock height z

Streets don't equal track in the least (I doubt you'd ever even see a 3psi increase on street). S-04 may be slightly less width (very slightly at that) but overall surface area is going to be more with the solid contact patches. Also when you have individual blocks like the as3 they squirm against each other causing the tire to overheat and become slippery.

The s-04 vs the as3 is not even in the same league.

Tell why I was able to run 12.9 on my stock Z with the as3 and my best with so4 was 13.1 on the drag strip? Btw I went multiple session/days with both tires

So straight line time now equals good handling? Interesting, those top fuel cars must be amazing on a road course then.

They need to re-evaluate their budget, because the v720's are having catastrophic delamination failures on all types of cars. And this is happening on autocross courses.

**** he just got his today. I'll warn him to watch out for it I guess.
