I had these installed on my car little while ago. I probably have 6 or 700 miles on them. Car is 2002 Saleen extreme convertible. Ordered the factory size that came on the factory 18 by 9 front 18 by 10 rear rims. 265/35 front 295/35 rear.
Straight line traction in dry conditions is great, traction in wet conditions is really good also. Problem is they feel very unstable on the highway. Speeds of say 30 to 40 mph up you notice it. The higher the speed the more unstable it feels. I can beat describe it as a "sway" type of feel. Like when you run slicks with low air pressure at the track and you would move the steering wheel left to right.
To remedy issue i used different pressure in the tires from 25 pounds up to 45 or 50 just to see. It is worse with lower pressure but still very noticeable at higher pressure. And car never performed this way with the old dry rotted, bald 12 year old Pirelli p zero's that were on the car before.
I did a lot of research before I bought tires and was very confident I made a great choice and was going to be happy with these, but i don't even like driving the car now!
Any thoughts? Could there be some sort of defect in the tires?? Thank you in advance for any help or info you can provide me with.
