I was gonna try 20psi on my race car but after
lowering it to the 20 I looked at the tires..
I was afraid it would hit the rims on the way
back down from the normal wheel stand.. they
were low.. also on my car I had 3/4" of stagger
on the front end.. the right tire was set back
the 3/4" to give me a littler longer time in the
lights to slow the reaction time.. I used a 24.5"
tall tire and the car reacted very quick.. I was
running a 1.19 60' on a normal basis unless the
tires were getting old(70-70 passes).. the rear
tires were MOST of the time set at 6 7/8 to 7 1/8
psi.. depending on the track.. this pic is with a
lower rpm launch and between the rpm and tire psi
it started rolling/folding the tires
