NOTICE: (Continued) If your tires havetoo much air (overinflation), you can get: Unusualwear 0 Badhandling 0 Rough ride 0 Needless damage from road hazards. 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). Tire Inspection and Rotation Tires should be inspected every 6,000 to 8,000 miles ( 10 000 to 13 000 km) for any signs of unusual wear. If unusual wear is present, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See "When it's Time for New Tires" and "Wheel Replacement" later in this section for more information. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See "Scheduled Maintenance Services'' in the Index for scheduled rotation intervals. 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. 6-36
