NEVER go by whats listed on the tire! That is a MAX pressure only. Always use whats listed by the manufacture on the door/pillar sticker. Tires will increase air pressure as they heat up, that is why there is a max COLD pressure on the tire, its not just the tire may explode by overinflation the rim flange could also fail causing a blow out. A tires 'footprint' also is affected by under/overinflation. The auto manufaturers work closely with tire manufacturers to determine the best inflation pressure for footprint/ride quality/safety compared to the weight of the vehicle. Set the inflation to the sticker no matter what tire/size you put on and adjust accordingly. 15" recomendation is 32psi cold, I run 35psi cold in my 215/45R17's. Changing inflations for autox is a different story, I am only refering to daily driving conditions.

The pressure printed on the tire is used only for load rating purposes. Its the "maximum" pressure which is allowed to meet the maximum load rating of the tire.
