Buying New Tires To find out what kind and size of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire's sidewall. When you get new tires, get ones with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have anall-season tread design, the TPC number will be followed an "MS" by (for mud and snow). A CAUTION: Mixing tires could cause you lose control while to driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you couldhave a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It's all right to drive with your compact spare (if you have one). was developedfor use on It your vehicle. If you ever replace your tires with those not having a TPC Specnumber, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. 6-43
