Why do you say they stink? Grip? Wear? Consistency? Wet performance?
poor,poor, good, dont know.
poor grip after about the 2-3 session. my sessions are an available time of 20 min practice, 20 min qualifying, and 20 lap race same schedule for both the days for the weekend, the race ends up ~30 minutes. for this wear rate, i may as well be on goodyear 160 slicks.
when they are fresh, first session, the grip is good. after that they are dropping off. by the 4th session, they are now my practice set.
very poor wear. my tires MUST be flipped after 6 sessions, i do this so that i can get the 12 sessions(wow!!!) out of them they they have been giving me before the (outer) edges are corded. I dont like the idea of spending $ to have tires flipped, that are already basically dead.
I/we have changed my/our set-up on the car around, i have changed my driving style around, and they just do the same thing, give up the outer edge while the rest of the tire has tread left. the grip, as i said is long gone after about the 3rd session compared to new.
from what we are getting from the tire guy at the track was first, raise the pressure up to 48 hot, then were were getting, lower the pressures. finally, he told us that toyo knows the tires are not working as they should, and that they are going to be reworked this summer.
My car is NOT the only one having the issues, its all of us.
SM has dumped them as the spec tire, and going back to the RA-1, and we will be also dump them for something, though the RA-1 isnt made in the size we need anymore.
the sidewalls just seem to tuck under the car, no matter what we do.
they are consistanly good the first few sessions, then they are consistantly dead. they also are consistanly wearing much faster than they should.
the tire guy was telling me the (fast)SM guys were shaving them to 1/64-2/64, and using them for 2-3 sessions.
I have not run them in the wet, so i cannot comment, the tread pattern looks like it might be a good rain tire.
I might have a dead one here to snap a picture of it, but i usually leave them with the tire guy at the track.
my spec 944 weighs in at 2625lbs coming off the track
the SM cars are around 2300 lbs
I just cannot see how the loss of a few more lbs i am guessing the lotus is 1900 lbs, plus driver(~200lbs) =~2,100 lbs coming off the track would make them suddenly shine.
likely the difference in being driven hard in races, and being driven under other circumstances is my guess.
I went through 4 sets this season ( 7 weekends with the car)
that was with rotating them EVERY session, and also rotating the more used tires as practice tires with my 2nd set of wheels.
now you know why I think they stink.
