Buying New Tires To find out what kind andsize of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle whenit 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 thatare designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have all-season tread an design, the TPC number will befollowed by an "MS" (for mud and snow). If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. Mixing tires could cause to lose control while you driving. Ifyou mix tires of different sizesor types (radial and bias-belted tires), the vehicle may not handle properly, andyou could have a crash. Using tires of different sizes may also cause damage to yourvehicle. Be sure touse the same size and type tireson all four wheels. with your compact spare, It's all right to drive though. It was developed for use on your vehicle.
