It is less stressful on a tire to be OVER inflated by 10psi than to be UNDER inflated by 10% (ie necessary pressure to carry actual load which may be less than max pressure of tire). Under inflation, you might remember, was the major cause of the all the Firestone Wrangler tires on Ford Explorers a number of years ago. Ford was the guilty party as they had recommended a lower inflation pressure to give a softer ride...until the tire blows and the ride is not so great. People were running the tires at the recommended empty load pressure recommendation, but carrying heavier loads without adjusting the tire pressures accordingly. Sidewall flex overheated the tires and they failed.

I have found little if any difference in the ride itself due to running a max pressure (ie measured while tire is at ambient temperature)
