My first mod is done, I received knock off GT 17" brushed aluminum wheels and tires today and put them on my V6. What is the recommended air pressure for the Pirellies? 36 psi? I sure did notice the steering was firmer and it takes a lot more gas to get moving (probably need a CAI now).
After I got home from being in bumper to bumper traffic I also noticed the rims were HOT, looks like they really pick up the heat off the brakes on all 4 wheels! Finally, I understood that these tires had the same circumferance as the OEM 16", but when I was replacing the tires I was able to get the original ones off, but then had to jack it up a few more notches in order to put the 17" on. Seem like when I get in the car it is sitting higher too. If I remember my high school math, circumference = diameter times pi (3.1415). Am I imagining it or just stupid?

I put the same rims on my V6 but I put on 255/50/17 on them which were the same distance around as the 16" tires that came off.I know the stock tires on the GT are 235's but don't remember the rest so they may be bigger around than the ones you took off.They will also throw your speedo off if the size changed very much.There area couple of websites out there that you can compare the tire size for circumference and what it does to the speedometer.Sorry I don't remember the websites but I am sure someone will let you know.

Cool, Thnaks guys! My speedo will be off by only 1 mph. What about the PSI for these? Is it supposed to be 36 psi?

Tire pressure shouldn't change, the vehicle weight is the same, as well as the suspension geometry. It should be the same on our V6s as the GTs. You can confirm this in your owners manual.:D
