Anyone have an idea what the tire pressure should be to run at the track for the best launch? Thanks.

 

Im curious too. Anyone know

 

Ironically this was asked in another thread only a week ago

And a search for "track tire pressure" brings up 30 hits, I'm just too tired to sort through them. But anyway, if you're driving an Evo with stock tires (and most AWD cars), I'd recommend about 38 all around on the track, 32 front/40 rear for autocross. For the Lancer (and most FWD cars), I believe 36 front/34 rear for the track, 34 front, 38 rear for autocross.

 

Those pressures are for track events which actually require turning, I would guess. The original poster asked about the best pressure to launch the car -- I'm guessing for drag racing...

In a high-powered 2 wheel drive car, you generally want to run lower pressures than normal for drag racing. For streetable cars with over 500 hp, pressures in the 10-15 psi range are not unheard of. By reducing the pressure, the contact patch gets much bigger, reducing or eliminating wheelspin. Of course once the car is past the launch phase, low pressure is just going to rob horsepower, so it's a balancing act.

Personally, I would set the tire pressure as high as possible while still allowing me to launch without wheelspin.

 

Sorry, my bad. I didn't notice the part about launching. Maybe move this to drag racing section would get better responses. My mind is always on road courses and autocross, serves me right for not realizing that a drag strip is a "track" too
