I run my KDW's at 36 front & 35 rear for normal driving.

They have normal tread wear and DON'T ROLL OVER on the sidewall like if I were to run them soft at say 32psi.

I inflate them above 40psi for autocross. (Final psi depends on surface, course layout, and temperature)


At the drag strip I run normal driving pressure in the front and sometimes inflate the rears to 40psi. I have dropped the fronts down to 32 or 30 and found no improvement in traction. It's not like you are going to get better weight transfer with softer tires/lower pressure. We drive the wrong wheels. You just end up getting a higher rolling resistance.

However my drag radials like 30-32psi best. Not surprising considering they are a softer compound with a softer sidewall. Then again that goes right back to the whole different tire philosophy.
