Recommended Tire pressure?

Always check your tire pressure after the car has
been at the tire shop - those guys love to swear by the
inflation pressure molded on the tire sidewall. They
even argue about it - to the point of disregarding your
instructions to do otherwise.

With the normal street tires I'd run 30 lbs (cold) in the rear and 31-32 lbs (cold) in the front. I'd use slightly higher pressure in the front tires to help compensate for the cars 51/49 weight distribution ratio but not 35 lbs...that's too much.

Cooler months I run 32 psi cold so that the pressure will be around 34-35 when up to operating temp. Hotter months, I run 30 psi cold so that the pressure will be around 34-35 when up to operating temps.
GM took into consideration the front/rear weight distribution when they spec'd 30 psi cold, and spec'd 30 psi for all four tires for how they wanted the car to react during cornering. For example, my Mercedes spec's 28 psi cold in the front and 32 psi cold in the rear and it's weight distribution is more biased to the front then the Corvette. When you start changing the air pressures front to rear you change the car's handling(understeer/oversteer) from what GM engineered the car for optimum handling.

Initially I did run all tires at 30 PSI as indicated. It was of late that I was told about this 35 PSI thing so my new tires will get the same outlook on life as my originals did by going back to 30 psi plus the ride is more comfortable.

I have all my tire work done at discount tire and they always use and recommend 30 lbs. pressure and 100 for the wheel bolt torque spec on the C6 vette. It even shows those on the receipt anytime they do any work on the car.

That is who told me this and on another occasion the person at alignment shop told me the same thing. I have always in the past followed sticker on label or in manual but was wondering why am I being told different.

Lots of people check their pressures after driving a few miles to the gas station, which warms things up. And better to be a couple of pounds high than a couple of pounds low.

The door sticker says 30 PSI (cold).
The manual says Max. inflation or 38 PSI which ever is lower for high speed driving.
I've noticed my tire pressures in the 35 - 37 PSI range once the tires have warmed from 30 - 32 PSI cold setting. This is with GY G2's.
If I'm going to be playing around I usually wait for the tires to reach that 35 - 37 PSI range to ensure they have warmed up.

Keeping mine at 32, but might drop it to 30 for a slightly better ride, due to no curves in the desert (180 miles on the clock). Remember we're dealing with RFs here, which have a much harder sidewalls than regular tires. I'd do 33 to 35 cold with regular tires, which I plan to install after the F1:G2s crap out. Good day.
