I tried the new tires out today. ran about 35 or 40 laps. showed alittle bit of wear on the right rear and right front. got some temp in them, that worrys me about blistering the tires. my right rear was about 160 in temp, after about 10 solid laps. are track was very dusty slick and windy here, did not have alot of water on the track at all. you have to get back in the gas quick because these tires have alot of grip and it wants to pull you to the right when entering the corners. It does make the guy that runs ok before, alot better now. It was kinda hard to pass. when i went out on my normal air pressure in my tires the car seemed to be real good, i tried dropping the rear tires some one time , that way i could build up air pressure, that didnt work. my car was all over the place. if you guys run alot of left rear bite in your car, your probably going to want to take some out. these tires bite, but you can still break the tires loose to and spin the s**t out of them. But overall i like them so far, some of are guys didnt, but its going to be one of those things that takes alittle bit to get the right feel for your car with these tires.
