Ok brief history, I have been to the local track a few times. It's an 1/8" track. I am running michelin ltx M/S 285/75/16, of which the rear two are just about bald. The last few trips down the track I have the front tires at 35-37PSI checked once the tires have been warmed up. The Rears have 40-42PSI. 60' time are alittle high between 1.89-1.93. I am working on aquiring some spring clamps to help. So I guess my question is if I am still hearing wheel spin/hop should I lower tire Pressure? If I lower tire pressure, lets just say 2-5PSI per pass? What is the lowest PSI before tire/rim separation? Thanks for everyones input.
