Yes 30 PSI. This is the big advantage of AT, you vave your power at the starting line and all the drivetrain is preload, so it is a big advantage on the reliability.
Last week end with the bad weather, I made 6 run and I made 12.14, 12.21, 12.32, 12.38, 12.44 & 12.54. 60, 1.73 to 1.87.
I have an rear alignment issue that wear-up my tire in less that 3000 miles I I put low treadwear tire. So I put 720 treadweat tire to prevent fast worn-out, but traction is very bad. Up to date my best 60' is 1.68.
I will try a set of Pirelli P zero. I only have 17" wheel to find, a friend of mone give me the tire.
I think I will try to use binder to hold down the front down.
