Tire pressure

[Redline]

I just got a set of new tires/rims. I haven't touched the pressure since I got them. Should I use the pressure on the inside of the door, or a little higher to get a bit of stiffness out of them? Oh by the way they are Nitto Extremes.

isn't 35 a bit high for normal tire pressure?

[A.S.]

Hehe I usually run 40 in front 32 in rear for a normal set of tires.

What's the best pressure for drag racing w/ street tires?

[ProtegeSTS]

hmm, no correct answer here as there are too many variables, but id start at about 25psi and expiriment to see where you get the best ETs. Remember that lower pressures = less middle contact patch AND more drag. <P>Even if you get a better 60', youre ET might stay the same.<P>Remember to pump the tires back up to normal pressures before leaving.

Yeah, although sometimes i just like screwing around to. LIke the car i learned to drive in a 1974 opel.. That car was a blast.. itty bitty rear wheel drive, some performance work had been done to it and the steering wheel was about 11 inches in diamiter =]
