Default A few "extra" PSI for better fuel economy??

Is anybody running at the "high" end of the recommended PSI in their S02's (or other brand of tire)??

With gas prices skyrocketing ($2.30 a gallon in CA for 91 octane), and roads quite dry, I thought it might save a bit over the long haul if I ran 36 PSI instaed of the suggested 32PSI...however, is there a "down" side as far as traction, or increased likelihood of punctures from road hazards (nails, glass, etc..)

Anybody have any comments or suggestions? I thought I'd try with 36PSI and see if there's any difference.

Thanks in advance.

Maybe 1-2 mpg better, BUT: rougher ride, tires wear quicker down the center, and less traction.

I am running my RE050 at 34 PSI cold tire pressure which I've checked in the norning before drive off.
Honda recommended 32 PSI is the minimum cold tire pressure, I've rather run my tires few PSI above minimum than under inflated tires.

I hate to incur someone's wrath, but if you were going to be worried about gas mileage, you should have bought a Miata.

I inflate my tires for top performance.

Daily high and low temperatures can be as much as 30 degree F. If you inflate your cold tire at recommended 32PSI at high temp of the day, your tires will be as much as 3PSI below recommended pressure at low temp of the day.
Which do you like to have, over-inflated by 3 PSI or under-inflated 3PSI tires ?
