Tire overloading Premature or irregular wear Poor handling Reduced fuel economy If your tires have too much air (over-inflation), you can get the following: • Unusual wear For additional information regarding how much weight your vehicle can carry, and an example of the Tire and Loading Information label, see Loading Your Vehicle on page 327. How you load your vehicle affects the vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry. When to Check Check your tires once a month or more. Do not forget to check the spare tire. If your vehicle has a compact spare tire, it should be at 60 psi (420 kPa). For additional information see Spare Tire on page 430. • Poor handling • Rough ride • Needless damage from road hazards A Tire and Loading Information label is attached to the vehicle's center pillar. This label lists your vehicle's original equipment tires and shows the correct inflation pressures for your tires when they are cold. The recommended cold tire inflation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle's maximum load carrying capacity. How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are under-inflated. Check the tire's inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). 403
