SERVICE AND APPEARANCE CARE Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. The amount of grip provided. Tread: The portion of a tire that comes into contact with the road. Treadwear Indicators: Narrow bands, sometimes called "wear bars," that show across the tread of a tire when only 2/32 inch of tread remains. UTQGS: Uniform Tire Quality Grading Standards, a tire information system that provides consumers with ratings for a tire's traction, temperature and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire. Vehicle Capacity Weight: The number of designated seating positions multiplied by 150 lbs (68 kg) plus the rated cargo load. Vehicle Maximum Load on the Tire: The load on an individual tire that is determined by distributing to each axle its share of the maximum loaded vehicle weight and dividing by two. Vehicle Normal Load on the Tire: The load on an individual tire that is determined by distributing to each axle its share of the curb weight, accessory weight, and normal occupant weight (distributed in accordance with Table 1 shown below) and dividing by 2. TABLE 1 - Occupant Loading and Distribution For Vehicle Normal Load For Various Designated Seating Capacities Designated seating capacity, number of occupants 2 through 4 5 through 10 Vehicle normal load, number of occupants 2 3 Occupant distribution in a normally loaded vehicle 2 in front 2 in front, 1 in second seat Tire Pressure Monitoring System If your vehicle is equipped with a tire pressure monitoring system, it uses pressure sensors containing a unique identification code to monitor the inflation pressure of the tires. When the inflation pressure of one or more tires indicates significant under-inflation, the tire pressure warning light comes on. If the warning light blinks, for approximately one minute and then illuminates continuously, the monitoring system may not be working. For more information, see "Tire Pressure Monitoring System Warning Light" in section 3. The tire pressure monitoring system does not replace normal tire maintenance. See "Inflation - Tire Pressure & Correcting the Tire Pressure" in this section for more information. Vehicle Placard: A label permanently attached to a vehicle showing the original equipment tire size and recommended inflation pressure. WARNING If the tire pressure warning light does not come on when the ignition is turned to the "ON" position, or comes on and blinks while driving there may be a problem with the tire pressure monitoring system. Have your vehicle inspected by an authorized dealer. 5-32
