What does temperature grade mean on tires?
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”.
What traction grade signifies the best traction?
Traction (the safety rating ) A traction grade tells you how well your tire can stop in wet conditions. The highest traction grade is AA, followed by A, B, and C. Tires with an ‘AA’ traction rating should stop at a much shorter distance than a tire with a ‘C’ rating.
What is a good treadwear rating?
In basic terms, and in the spirit of the concept, the higher the UTQG treadwear rating, the greater the tire life. A tire with a “600” treadwear rating is forecasted to last twice as long as a tire with a “300” rating, and should accumulate three times the mileage of a “200” rated tire.
What is normal tire temperature?
How hot does the tire get? Typical tires experience a temperature increase of roughly 50 degrees after running on the highway for a half-hour. If it’s a 70-degree day, this suggests a tire temperature of about 120 degrees.
What is the best temperature rating for tires?
In fact, 98 percent of all tires tested ranked better than the control tire. Temperature, the tire’s heat resistance, is stated in letters. A tire graded “A” is the highest, “B” is average and “C” the lowest.
How many miles is a 600 treadwear rating?
A tire rated 600 AA with a 70,000 mile warranty is quite likely to live up to it.
What does tire traction A mean?
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”
Which traction grade is the highest?
The traction grades, from highest to lowest, are AA, A, B and C. These grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
How many miles is a 400 treadwear rating?
For example: One tiremaker’s 400 treadwear grade earns only a 40,000- mile warranty, while another’s 400 -level tire carries a 60,000- mile warranty.
What does 400 AA mean on a tire?
“UTQG” stands for “Uniform Tire Quality Grading”. Example: a tire with a UTQG of 400 AB. The 400 is tread wear which represents the tire’s comparative wear when measured against the governments mandated tire, which is rated at 100.
What tire has the longest tread life?
Top 10 Longest Wearing All-Season Tires
- Cooper CS5 Grand Touring.
- Goodyear Assurance TripleTred All-Season.
- Continental True Contact.
- Yokohama Avid Ascend.
- Michelin Defender.
- General Altimax RT43.
- Bridgestone Dueler H/L Alenza Plus.
- Continental CrossContact LX20.
What are the best high mileage tires?
The longest lasting tires in Consumer Reports’ tests are the Pirelli P4 Four Seasons Plus. They claim 90,000 miles, and Consumer Reports estimates they’ll go 100,000. Consumer Reports says don’t expect to get all your money back if your tires wear out before the mileage warranty.
Is 40 psi good tire pressure?
Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “ recommended tire pressure ” of 33 psi, Gary. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.
What is a dangerous tire temperature?
Most experts consider 195 degrees Fahrenheit as the “line in the sand” when it comes to tire temperature: Beyond that point, the temperature will start impacting tire life. At 250 degrees, a tire will start to lose structural strength, could begin experiencing tread reversion and the tire will begin to lose strength.
How much does tire psi go up after driving?
The rule of thumb (best understood as our American counterparts put it) is that tire pressure will go up approximately one pound per square inch ( PSI ) for every 10 Fahrenheit increase in temperature.
