what tire pressure to run for drag racing?

i have 4 new nitto nt555's on my 05 sti..when i get the car back and properly break it in im gonna hit the track to get some new and better times..last time i went i was runnin the reccomended tire pressure,36lbs..and it was way too much pressure..what would be a good tire pressure to run..they're not the drag radials they're just summer tires

 

I think the lower the pressure, the more grip you'll have. But running them too low could be bad for your tires.

Maybe start around 29-30lbs?

 

I've heard much conflicting advise on this issue... half say run 30 psi for "more grip", half say run 42 so you'll get "a little wheelspin" so you don't bog down.... I don't know...

 

I prefer the higher tire pressure train of thought.

I'd much rather have wheelspin than have to deal with a broken axles.

 

^^^ this guy would know... I've seen him rip 12's................

 

on 36 it was trying to wheelhop really bad..and that was the first day my clutch ever slipped..so idk..ill try both..i carry a compressor with me anyways

 

pEd ran 12's.....nice man!!!

 

i ran 30 in the mountains, it was perfect.

 

I've ran 11's on the WRX tranny and stock block. I ALWAYS have my tire pressures between 34-38. Promote a little tire spin but not too much. Too much grip will kill your lower times due to bogging. Every car is different due to different weights, tires, and power levels.
