What does AA on a tire mean?
Traction also receives letter grades that indicate how well it stops. A tire having a higher grade should allow a car to stop on a wet road in a shorter distance than a tire with a lower grade. Traction is graded “AA” (highest), “A,” “B” or “C” (lowest).
What does AA traction rating mean?
Traction. Traction markings indicate how well a tire will perform in wet conditions. The traction rating can be AA, A, B or C. AA is the highest level of wet traction and C is the lowest.
What is a good UTQG rating?
The system is fairly easy to understand. A tire with a treadwear grade of 400 should have a useful tread life approximately twice as long as a tire with a treadwear grade of 200. The higher the grade, the better the expected treadwear.
What does UTQG 720 AA mean?
A UTQG rating is made up of a three-digit number and two letters or letter groups. For example, a tire might have a 720 A A rating. The first letter or group of letters is the traction rating. The best grade is AA, followed by A, B and C. The better the grade, the better the tire will stop in wet conditions.
What does UTQG mean on a tire?
Uniform Tire Quality Grading
The Uniform Tire Quality Grading is a comparative assessment applied to most car tires (excluding winter tires) to help consumers make informed decisions. The manufacturers grade the tires themselves for temperature, traction, and treadwear.
What does 400 AA mean on a tire?
The 400 is tread wear which represents the tire’s comparative wear when measured against the governments mandated tire, which is rated at 100. So the tire rated at 400 would wear four times longer than the government’s mandated tire.
Is a higher or lower UTQG better?
The UTQG (Uniform Tire Quality Grade) treadwear rating, also known as a treadwear grade, is a number stamped on the tire sidewall that relates to expected tire life. In basic terms, and in the spirit of the concept, the higher the UTQG treadwear rating, the greater the tire life.
Which traction grade signifies the best traction?
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.
Is a higher treadwear number better?
Tread wear (the durability rating)
This number designation is designed to give you a picture of the durability or life you can expect from your tire. The higher the tread wear number, the longer the tread wear will last. In this case, a higher number is better than a lower number.
What are three UTQG ratings?
The UTQG rating is made up of three components, treadwear, traction and temperature.
How long will 200 treadwear last?
A tire rated at 200 has a projected tread life of 60,000 miles.
What is a good treadwear number on tires?
For enthusiasts, the best part of the treadwear spectrum is the lowest part. Tires with treadwear ratings of 350 or less tend to have some performance pretentions, but for serious drivers and competitive racers, the only tires they will ever consider have treadwear ratings of 200 or less.
How does treadwear rating work?
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one half times as well on the government course as a tire graded 100.
How long should automobile tires last?
On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.
