when tested undercontrolled conditions on a speci€ied indoor laboratory test wheel. Sustained high temperature can cause the material of the tireto degenerate and reduce tire life, and excessive temperature canlead to sudden tire failure. The grade C corresponds to a level of performance meet which all passenger car tires must under theFederal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature gradefor this tire is established for a tirethat is properly infiated and notoverloaded. Excessive speed, underinflation, or excessive loading,either separately or in combination, can cause heat buildup and possible tire failure. These grades aremolded on the sidewalls of passenger car tires. While the tires availableas standard or optional equipment on General Motors wh i vehicles may vary t respect to these grades, all such tires meet General Motors performance standards and have been approved for on General Motors use vehicles. All passenger type (P Mdtric) tires must conform to Federal safety requirements in addition to these grades. Wheel Alignment and Tire Balance The wheels on your vehiclewere aligned and balanced carefullyat the factory to give youthe longest tire life and best overall performance. In most cases, you will not need to have your wheels alignedagain. However, if you notice unusual tirewear or your vehicle pullingone way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. Your dealer will lmow the kind wheel of you need. Each new wheel should have the same load carrying capacity, diameter,width, offset, and be mounted the same wayas the one it replaces. If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only wt new GM ih original equipment parts. This way, you will be sure tohave the right wheel, wheel bolts, and wheel nuts for your Oldsmobile model. Wheel Replacement Replace any wheelthat is bent, cracked or badly rusted. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your Oldsmobile dealer if any of these conditions exist. 213
