Speed Rating

• Speed ratings for tires were developed to assist car manufacturers in matching up the top-speed capabilities of an automobile with the appropriate tire that can handle the maximum sustained speed ability of that particular automobile. Kelly Trex Tire specs have a speed rating of "S," which allows for a sustained maximum speed of 112 mph.
  
  

Treadwear Warranty

• Treadwear warranties are used to give consumers a general idea of how many miles a tire will last before it will need to be replaced. For example, Kelley Trex tires have a warranty of 50,000 miles. This indicates that the tread on the tires will last until roughly 50,000 miles of usage. The warranty, however, is not concrete and the longevity of tire tread is dependent upon the type of vehicle, the weight of the vehicle and how fast the vehicle is driven by the consumer.
  
  

UTQG Treadwear

• Uniform Tire Quality Grading System (UTQG) Treadwear is a federally mandated method of "grading" the life of a tire's tread. It takes into account temperature, traction and treadwear, and assigns a value accordingly. The value of a Kelley Trex Tire is 500, which is indicative of a long tread life. Of course, the longevity varies depending on driving conditions and on how the car is driven, the type of vehicle and other variables.
  
  

UTQG Temperature

• Uniform Tire Quality Grading System (UTQG) Temperature is a federally mandated method of "grading" the amount of heat buildup that a tire can tolerate. Grades are assigned on a basis of A, B and C with "A" being the best and "C" being the worst. Kelley Trex Tires have a UTQG Temperature rating of "A."
  
  

UTQG Traction

• Uniform Tire Quality Grading System (UTQG) Traction is a federally mandated method of "grading" the a tire's ability to stop on a slick surface area. Grades are assigned within a range of (from best to worst) AA, A, B and C. Kelley Trex Tires have a UTQG Traction rating of "A."
