10-42 Vehicle Care Warning (Continued) . Warning (Continued) and a serious crash. See Vehicle Load Limits on page 9-10. . All-Season Tires This vehicle may come with all-season tires. These tires are designed to provide good overall performance on most road surfaces and weather conditions. Original equipment tires designed to GM's specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be "MS." Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires on page 10-43. Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when the tires are cold. Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact - such as when hitting a pothole. Keep tires at the recommended pressure. (Continued) Worn or old tires can cause a crash. If the tread is badly worn, replace them. Replace any tires that have been damaged by impacts with potholes, curbs, etc. Improperly repaired tires can cause a crash. Only the dealer or an authorized tire service center should repair, replace, dismount, and mount the tires. Do not spin the tires in excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode. . . . .
