I never had 18's before, so can anyone give me some feedback on the air pressure to run in a 225/40...?

Also, does anyone know what the tourque spec is for tightening your lugs...?

Should still be the same 30 to 35 psi and 75 to 80ftlbs of torque on the lug nuts.

that seems awfully low for air pressure... I was thinking it should be like 42-44psi...?

Dunno my nittos are rated at 35 psi. I could be wrong though.

32 & 28...? is that measured as PSI...?

I run 40psi, my v6 seemed to be to heavy to run lower pressure. I have 22/40's

Torques specs are 90 pounds. You can go higher but you stand a chance of warping rotors. I have not had a problem with loosening at 90

I was pretty sure the spec was 80ftlbs on the lugs. They don't have to be super tight. I run mine at 78 and don't have any problems at all.

air pressure for your car should be 38-40 lbs thats more than enough to give you a good ride and even tire wear. 35 is al ittle to low you might damage your tire if you hit a bump, not enough cushion.(youll pinch the tire and youll get a nipple on it not good)
