Pump the pressure up a 1/2 lb. at a time until it spins and then go down the other way 1/2 lb. from where you started to see what the high and low pressure limits are for your car and these tires
Test, tests until your the fastest guy in your deal

Cab thats what I did w/th bias ply tires. Just need to get to a T&T.

Hey Tom...Bob put some PHX radials on last year; Good for a .08 better ET in the 1/4 and 3 final rounds later he says he likes them. They like lots of air pressure...Also figure on a little more RPM at the finish line, because they do not grow like a bias.

And NO SCREWS!!! if they move a little, rotate and make a pass to lock them in. If that does not work a little tack will help.

Hi Mike. I like them so far. I'm off about 30 thousands right now. Once I get the air pressure set where the car likes it that should come back. Hope to get out to Quaker Friday for test and tune. If not I will run at Mag on Sunday and play with the tire pressure then.
