I agree with all the tire comments. I have seen increased handling when the tires (Michelin) are inflated to about 40 psi. My one concern is when they get hot, after a very long trip (500+ miles), I have seen them hit about 50 psi.

I don't have the best pressure gauge though.

The net is (as far as I am concerned):

Increased psi = better handling, mpg
Normal psi = better ride

I will take the better handling and mpg over ride (I came from the truck world).
