Ok, another question for the smartest Corvette people I know. My front tire states: 51 psi max pressure and my rear states: 45 psi max pressure but there is 30 psi in all 4 tires. Is that ok?

The specification for your car is on the door (sometimes, older cars have the specification on the inside of the glovebox or console lid, or printed in the owner's manual). And it will almost always be way lower than the max tire pressure stamped on the sidewall of any tire. Just so you know.....

Only reason I mention it is that the traction control computer is looking for a particular ratio of revolutions per mile between the front and rear tires. If that ratio gets too far off from what is expected, then the computer will assume that some tire or tires is losing traction with the road. This can cause it to intervene and it will be very unexpected to the driver. I have never seen on the forum what the actual specification is, but if you are going to get new tires anyway, no reason not to get the OEM sizes to avoid possible problems.
Consider the Michelin Super Sports when you replace them. They are not run flats right now but the base C6 sizes (the correct ones) will be soon since the C7 has them.

A local autocross wizard had the original non-runflat PS2's on his Z51 car, then switched to runflat PS2's which he and his wife used to win the regional championships a few years ago. He told me there was no discernable difference in noise or ride between the two tires, and the runflats seemed to handle a little better.
The C5 Goodyear runflats certainly earned the name Runcraps, but newer designs are much better.

Goodyear run flats where on my Vette when I purchased it they developed a bubble in the front tire so I switched to Firestone run flats smoother ride & less road noise!!
