When It's Time forNew Tires One way to tell when it's time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch ( 1.6 mm) or less of tread remaining. 0 0 The tire has a bump, bulge or split. The tire has a puncture, cut, or other damage that can't be repaired well because of the size or location of the damage. Buying New Tires To find outwhat kind and size of tires you need, look at the Tire-Loading Information label. The tires installed on yourvehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire's sidewall. Whenyou get new ti.res, get ones with that same TPC Spec number. That way, your vehicle will continue to have tires thatare designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by an "MS" (for mud and snow). You need a new tire if 0 You can see the indicators at three or moreplaces around the tire. You can see cord or fabric showing through the tire's rubber. 0 0 If you ever replaceyour tires with those not havinga The tread or sidewall is cracked, cut or snagged deep TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, enough to show cord or fabric. bias-belted or radial) as your original tires. 6-37
