Making the Tire Grade… A Quick Guide to Tires

  1. 1. Making the Tire Grade… A Quick Guide to Tires <br /> <br />August 9, 2010<br />
  2. 2. If a car owner wants new tires where should they start? <br />There are dozens of major tire manufacturers in the United State each with dozens, sometimes hundreds of unique tire lines <br />Gathering information is as good of a place as any and the Uniform Tire Quality Grading (UTQG) system contains helpful information that can guide consumers in their purchase. <br />
  3. 3. Standard Grading System<br />The U.S. Department of Transportation (DOT) and National Highway Traffic Safety Administration (NHTSA) established the UTQG to create a standard grading system for three different tire components - treadwear, traction and temperature <br />
  4. 4. Know the Grade<br />Car owners can find these grades when visiting a local tire retailer on the tire itself; specifically, the paper labels on the tread and actually molded on the sidewall. <br />
  5. 5. Making the Grade<br />Tire manufacturers conduct testing for the UTQG using independent testing companies.<br /> Even though the government doesn’t conduct the tests, they inspect the data and hand out penalties for inaccuracies <br />
  6. 6. Treadwear<br />The treadwear grade is comparative based <br />Cars are tested under controlled conditions on a test track and given a rating depending on their wear rate <br />Tires with a rating of 200 lasted twice as long on the test track as tires with a rating of 100. <br />
  7. 7. A Word of Caution <br />Treadwear grades aren’t directly proportional outside the store for a few reasons. <br />The first is that condition of roads, driving habits, climate and service practices all factor in to how long tires last (which the tests can’t take into account). <br />Also, since different manufacturers have different grading schemes using treadwear grades to compare tires from specific manufacturers works better then using it to compare tires from competing manufacturers <br />
  8. 8. Traction<br />The traction grade represents the level of grip tires have, the UTQG tests the tire's ability to stop on wet pavement <br />The test evaluates a sliding tire at a constant speed (40 mph) by locking the brakes in order to measure its coefficient of friction as it slides <br />
  9. 9. Traction Cont.<br />The testing doesn’t take into account cornering, hydroplaning or acceleration. <br />There are four different ratings, from highest to lowest – “AA,” “A,” “B,” and “C.” <br />The “AA” rating is relatively new and was added in 1997. <br />
  10. 10. Temperature<br />The temperature grade represents the tire's resistance to the generation of heat <br />There are three grades, from highest to lowest – “A”, “B” and “C.” <br />A tire with a “C” rating means under the test conditions it had the minimum performance. A “C” doesn’t mean it’s unsafe, just that it will run hotter than one with an “A” rating <br />Heat is what causes tires to deteriorate over time<br />
  11. 11. The UTQG isn’t the only thing to consider when purchasing tires, but it’s a good source of information and knowing what they mean helps put them in context. <br />Driving style, type of vehicle, climate, brand name and price are all things to consider along with the three UTQG ratings. A helpful sales professional at your local tire retailer can also assist you when choosing the tire that’s right for you and your style<br />
