NOTICE: Don't letanyone 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 Bad wear Bad handling Bad fuel economy. If your tires have toomuch air (overinflation), youcan get: Unusual wear Bad handling Rough ride Needless damage from road hazards. When to Check Check your tires once a month or more. 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. Theyhelp prevent leaks by keeping out dirt and moisture. 6-43
