gotta run a gauge.
gotta 'adjust the nut behind the wheel.'
Ran higher psi for 200,000+ miles....never had a grip problem.
Went a size up on tire, to lower rpms while on freeway.
see links in sig for other mods
PS. never turned the AUto a/c off and still got 30+ mpg. If you are gong to drive a luxury car....ride in luxury!!!!

Exactly! The car may not get the economy of a 1.5L but it sure is comfy and quiet on the highway. The V8 is nice for those ramps too. When you say you ran high pressure for 200,000+ miles, did your tires wear unevenly? I've had Bridgestone Turanza Serenity for about a year and they're supposed to be on the fuel economy side. Before I had 10 year old michelins and ran those up to 40psi because frankly I didn't care. I just don't want the new tires to wear out prematurely. Oh since this is a RWD car, I have cheap snow tires that I put on it as well, it really helps with the snow bands on the toll road.
