This information indicates the rela- tive performance of passenger car tires in the area of treadwear, traction, and temperature resis- tance. This is to aid the consumer in making an informed choice in the purchase of tires. Quality grades can be found where applicable on the tire sidewall be- tween tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Tem- perature A 3. The total weight now exceeds the capacity weight by 32 lbs (15 kg), so the cargo weight must be reduced by 32 lbs (15 kg) or more. The quality grades apply to new pneumatic tires for use on passen- ger cars. However, they do not apply to deep tread, winter type snow tires, space-saver or tempor- ary use spare tires, tires with nominal rim diameters of 12 inches or less, or to some limited produc- tion tires.
