Maintenance and Care RWARNING When replacing full size tires, never mix radial, bias-belted, or bias-type tires. Use only the tire sizes that are listed on the tire pressure decal. Make sure that all tires are the same size, speed rating, and load-carrying capacity. Use only the tire combinations recommended on the decal. If you do not follow these precautions, your vehicle may not drive properly and safely. RWARNING Make sure that all replacement tires are of the same size, type, load-carrying capacity, and tread design (e.g. "All Terrain", etc.), as originally offered by Ford. RWARNING Failure to follow these precautions may adversely affect the handling of the vehicle and make it easier to lose control and roll over. Tires that are larger or smaller than your vehicle's original tires may affect the accuracy of your speedometer and odometer. Wheel and Tire Matching See an authorized tire dealer for proper servicing procedures. Wheels and tires must be properly removed, matched and remounted to maintain the best possible ride. Information About Tire Quality Grades New vehicles are fitted with tires that have their Tire Quality Grade (described below) molded into the tire's sidewall. These Tire Quality Grades are determined by standards that the United States Department of Transportation has set. 305
