You need new tires if any of the following statementsare true:. You can see the indicators at three or more placesaround the tire.. You can see cord or fabric showing through thetire's rubber.. The tread or sidewall is cracked, cut, or snaggeddeep enough to show cord or fabric.. The tire has a bump, bulge, or split.. The tire has a puncture, cut, or other damage thatcannot be repaired well because of the size orlocation of the damage.The rubber in tires degrades over time, even if they arenot being used. This is also true for the spare tire,if your vehicle has one. Multiple conditions affect howfast this aging takes place, including temperatures,loading conditions, and inflation pressure maintenance.With proper care and maintenance tires will typicallywear out before they degrade due to age. If you areunsure about the need to replace your tires as they getolder, consult the tire manufacturer for more information.Buying New TiresGM has developed and matched specific tires for yourvehicle. The original equipment tires installed on yourvehicle, when it was new, were designed to meetGeneral Motors Tire Performance Criteria Specification(TPC spec) system rating. If you need replacementtires, GM strongly recommends that you get tires withthe same TPC Spec rating. This way, your vehicle willcontinue to have tires that are designed to give thesame performance and vehicle safety, during normaluse, as the original tires.GM's exclusive TPC Spec system considers over adozen critical specifications that impact the overallperformance of your vehicle, including brake systemperformance, ride and handling, traction control, and tirepressure monitoring performance. GM's TPC Specnumber is molded onto the tire's sidewall near the tiresize. If the tires have an all‐season tread design, theTPC spec number will be followed by an MS for mudand snow. See Tire Sidewall Labeling on page 7‑58 foradditional information.GM recommends replacing tires in sets of four. This isbecause uniform tread depth on all tires will help keepyour vehicle performing most like it did when the tireswere new. Replacing less than a full set of tires canaffect the braking and handling performance of yourvehicle. See Tire Inspection and Rotation on page 7‑70for information on proper tire rotation.7-72Ofrecido por www.electromanuales.com
