Inflation Tire Pressure The Tire-Loading Information label which is on the rear edge of the driver's door showsthe correct inflation pressures for your tires, when they're cold. "Cold" means your vehicle has been sitting for at least three hours or driven no more than a mile. - When to Check Check your tires once a month or more. Don't forget your compact spare tire. It should be at 60 psi (420 kPa). How to Check Use a good quality pocket-type gage to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires -- which may look properly inflated even if they're underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture. NOTICE: Don't let anyone tell you that underinflation or overinflation is all right. It's not. If your tires don't have enough air (underinflation) you can get: Too much flexing Too much heat Tire overloading Badwear Badhandling Bad fuel economy. If your tireshave too much air (overinflation), you can get: Unusualwear Bad handling Rough ride Needless damage from road hazards. 242
