Tire Wear: Toyo R888s/Track Use ONLY

[michael lang]

I also have R888s on my car which only have 3 days on them, I usually end up somewhere in the 38-40psi range in the front and about 44 psi in the rear. by the end of the session, the car feels very, very planted. my alignment specs are -1.9 camber in the front and -2.5 camber in the rear,  I can't remember what the caster and toe measurements are right now. my car's corner balance is 48%...left side 51%...right side. interestingly enough, the tires consistenly had within about 7-8 psi increase no matter which session (read that as time of day) I was driving in. one thing that I know that I must get is a pyrometer so I can get more accurate temperature measurements on how hard the tires are working. my tires after 3 days of absolute flogging look very good with even wear across the tread pattern. last season my car did have an alignment issue but more importantly it had a balance issue to the point where a perfectly good right front tire was destroyed in 2 track days. I don't know this for sure with your car but my guess would be that the issue with your car maybe in the balance of the car. I would suggest getting the car to a shop that has scales so a corner balance can be performed and then the ride height and alignment can be done at the same time.  you will be amazed at how wonderful a balanced and aligned car really is.
