What tire PSi for 1/4 for stock tires?

I'm going to try my car in 1/4 mile. What tire PSI should I run on the back on stock 18's.

Thanks.

I would go ahead and start at 22 then ck after the run and make sure it is 24 or less HOT. Drive around the deep water and then back up onto the wet area then pull back up just ahead of the wet so you have water on the tire but not in the tread and then do a good smokey burn out. Rapidly off the clutch and on the brake just like a old fashion automatic brake torque. 3000 rpm and release the clutch smoothly as power is applied....you don't want it to spin but the rpm needs to stay above 2500 - 3000. Good luck

I imagine it is different per track, but like Tony stated go low. I actually had my best luck at 19-20 lbs in the rear, but the one thing folks forget is the
front----- pump them suckers up. I was running my 98 at 50lbs., but I ran the 2000 at 45lbs in the front. Good luck and post your times.
