cornering (turning) traction. TEMPERATURE The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. UNIFORM TIRE QUALITY GRADING LOCATING THE GRADE Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. Treadware 200 Traction AA Temperature A WARNING! The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. pg. 82 Spare tire Special Spare The spare tire in your car is called a "Special Spare". It has the following designation: 124/90 R15 96M. Recommended tire pressure (see the bottom line of the decal on the fuel filler door) should be maintained irrespective of which position on the car the Special Spare tire is used on. In the event of damage to this tire, a new one can be purchased from your Volvo retailer. WARNING! Current legislation prohibits the use of the "Special Spare" tire other than as a temporary replacement for a punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be affected with the "Special Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).
