Tire pressure/Gas mileage
I just recently put on GT takeoffs and was wondering what is the recomended air pressure and if I was to over or under inflate these tires what advatages or disadvatages (mpg/tire wear) I would enconter.
Thanks Bob

RE: Tire pressure/Gas mileage
If you underinflate you'll have too much wear on the edges. If you overinflate you'll have too much wear in the center. That's a good way to figure out what pressure you should be at, but it takes a long time and basically by the time you find out it's time to change the tires, which is fine as long as you don't change the suspension or the tires you go with. Another way is to start off at the factory inflation and then add to the front if you want more oversteer (obviously tire pressure adjustment can only do so much for over/understeer) and to the rear for more understeer. The higher the pressure, thebetter the mpg, but if the pressure is too high, you'll be shrinking the contact patch. Ideally, you'd have a Motec and would set the tires such that the temperature in the middle of the tire is higher than the outside and cooler than the inside.

The higher you go the more of a nut-busting ride. Even at the manufacturer's max pressure you won't gain much in the way of mileage.
I typically run my Goodyear F1's at 32-33 PSI. I started at 35 when I first put them on and worked down to 30 in 1 PSI increments and then back up to 35. I settled on 32-33 for the best compromise in handling and ride comfort. It's something that you alone will have to decide on.

What's the sidewall say? If it says 44 PSI Max, I usually inflate to 37 PSI. If it says 35, I put it at 32-33PSI. Again though, it's your preference. Keep in mind if you put too low of a pressure you will compromise MPG by 1-2 or even 3mpg depending as to how underinflated you keep them.
