I was wondering what is the best air pressure to run in the F-1's for the best possible launch on the street? Does it help to run more air pressure in the front tires?

I usally run mine at 15 psi when I go to the track. Some say its bad for them, but I launch pretty good.

I always found with the f1's around 28-30#'s worked the best for me! by keeping that pressure it seemed to put all of the tire to the ground. when i ran less pressure the tire seemed to cup in the center resulting in tire spin..just my .02 JL

JL,

I have to agree with you. I've tried lowering the pressure and if anything it got worse. I think I ran a tick slower on the big end too.
About 28#'s is where I keep them.

I usually pump the fronts up to 35#'s when I go to the track. Less rolling resistance.

I run 35 lbs up front. I figure the more air in 'em, the less rolling resistance - within limits.

I run 30 lbs at the rear. Same reason as JL said.

I run my F1's at 15 psi and they work great. I have tried at 25, 30 and I like them better at 15. Mine hooked awsome with 15 psi. Somepeople say it hurts the tire but Mine don't last that long anyway. I really need to invest in a drag setup.
