Here's a multiple choice question from the Car Care Council that has fooled more than one expert. Keeping tires properly inflated extends their life and saves fuel.

Correct inflation is (a) written on the sidewall of the tire; (b) 32 p.s.i.; (c) listed in the owner's manual; (d) posted on a sticker on the door jamb.

The answer is (c) or (d). The maximum load and maximum inflation pressure stamped on the tire's sidewall are exactly that: MAXIMUM recommended for that particular tire. Excessive inflation and load not only can damage the tire, it also can accelerate wear.
