Default torque and pressure

Doe's anyone know what the ft lbs the Z06 factory rims get torqued at? Also what is the deal do you follow GM 30psi all around for tires or what the tire manufacture says or somewhere in the middle.

100 ft lbs is the setting and GM recommends 30 psi cold. I try to go 30 psi hot so that comes out to about 28 psi cold.

I set mine to 28 psi cold also.

Thanks, I'm installing nitto 555R11 R extreme and I'm excited and my fingers are crossed these tires are the answer to my love for the twistys and the need for straight line performance.

I run 30 psi front, 28 psi rear on C5 Coupe. I get 55,000 miles fron fronts and 45,000 miles from rears, using OEM Goodyear Run Flats.

100 ft-lbs torque, drive 50-100 miles and re-torque.

Please post your thoughts on the new tires when you get a chance. I need to replace my F1's and I'm considering some Nittos. I have no traction till fourth gear, need some better tires!

Thanks
