Actually Tire Ratings are very important for the customer and the tire dealer. Twin Tire's service technicians are well informed of all the tire ratings and what they mean, but an educated customer is a good customer. We Can Help You With That!
When buying tires in the Harvey or Hammond area.. Even New Orleans or most places in Louisiana you driving needs directly impact the type of tire you need. When comparing pricing, tire ratings are important to know you are making the right comparisons.
This grading system, known as the Uniform Tire Quality Grading System (UTQGS), allows consumers to compare tire treadwear, traction performance, and temperature resistance. The federal government requires tire manufacturers to grade their tires in these three areas and place the information on the sidewall of the tire.
- Understanding the treadwear grade
- Understanding the traction grade
- Understanding the temperature grade
Tire Ratings - Treadwear
Treadwear grades are an indication of a tire's relative wear rate. The higher the treadwear number is, the longer it should take for the tread to wear down.
A control tire is assigned a grade of 100. Other tires are compared to the control tire. For example, a tire grade of 200 should wear twice as long as the control tire.
Of current tires:
- 15% are rated below 200
- 25% are rated 201 - 300
- 32% are rated 301 - 400
- 20% are rated 401 - 500
- 6% are rated 501 - 600
- 2% are rated above 600
Tire Ratings - Traction
Traction grades are an indication of a tire's ability to stop on wet pavement. A higher graded tire should allow a car to stop on wet roads in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest as "AA", "A", "B", and "C".
Of current tires:
- 3% are rated "AA"
- 75% are rated "A"
- 22% are rated "B"
- only 1 line of tires rated "C"
Tire Ratings - Temperature
Temperature grades are an indication of a tire's resistance to heat. Sustained high temperature (for example, driving long distances in hot weather), can cause a tire to deteriorate, leading to blowouts and tread separation. From highest to lowest, a tire's resistance to heat is graded as "A", "B", or "C".
