The UTQG rating system originated in the US as a way to help consumers make more informed tire-buying decisions. Tire manufacturers give their own tires a grade for treadwear, traction and temperature. Together, these numbers makes up a tire’s UTQG rating—a three-digit number plus two letters.
Keeping this in view, what does 500 AA mean on tires?
Over 500= about 80,000 miles. 5. Traction – The traction grades, from highest to lowest, are AA, A, B, C. This rating represents the tires ability to stop on wet pavement as measured under controlled conditions. A tire marked C traction may have poor traction performance.
What does Traction AA mean on a tire?
Traction. Traction grades, from highest to lowest, are AA, A, B and C. They represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete.
What does the treadwear number mean on a tire?
Treadwear grade. A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100. But the numbers are assigned by tire manufacturers, not an independent third party.
Why is it not recommended to fix a tires sidewall?
Repair of any punctures in the shoulder and sidewall areas are not permitted. This tire has been punctured in the tread area by a screw less than 1/4″ in diameter. If no internal damage is found when the tire is dismounted, this puncture can be repaired following industry guidelines and the tire returned to service.
How often do you need to rotate your tires?
However, check your owner’s manual to see if there is a recommended rotation scheme. During rotation, each tire and wheel is removed from your vehicle and moved to a different position to ensure that all tires wear evenly and last longer. Tires should be rotated every six months or 6,000 to 8,000 miles.
What causes tires to wear unevenly?
Improper tire alignment can cause your tires to wear unevenly and prematurely. Common irregular tire tread wear conditions from improper alignment include the following: Heel/toe tire wear: This happens when one side of the tread blocks is wearing faster than the other side circumferentially.
What is a tire speed rating of H?

What does the UTQG rating for a tire mean?
“UTQG” stands for “Uniform Tire Quality Grading”. A system developed by the Department of Transportation, which helps consumers compare and rate tires on tread wear, traction, and temperature. Example: a tire with a UTQG of 400 AB. However, please don’t link treadwear grades with your projected tire mileage.
How do you read a tire size?
A European metric tire would have no letter before the tire size.
245 = Section Width. Tread (mm) The section width is the width of the tire from one sidewall to the other measured in millimeters.
45 = Aspect Ratio. (Ratio of Sidewall height to width)
19 = Wheel. Diameter.
98 = Load. Index.
What is the best Utqg?
No, “UTQG” is not a play dictated by Peyton Manning during a Super Bowl huddle. The Uniform Tire Quality Grade 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 tread wear.
Why is it important to have your tires rotated?
Tire rotation is the practice of moving the wheels and tires of an automobile from one position to another, to ensure even tire wear. Even tire wear is desirable to extend the useful life of a set of tires. The weight on the front and rear axles differs which causes uneven wear.
What does the load range on a tire mean?
The load-carrying capacity of Pmetric tires is rated as either Standard or Extra Load. Standard Load tires are limited by the load that can be supported with a maximum inflation pressure of 35 psi. Extra Load-rated tires are limited to the load that can be carried at a maximum inflation pressure of 41 psi.
What is the aspect ratio of a tire?
The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.
What is the difference between load range D and E?
Expert Reply: Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.
What does 113 mean on a tire?
Answer. See all questions about this product. Showing 1-3 of 3 answers. 113 is the load rating, it means the tires can handle up to 2535 lbs. S is the speed index, which means the tires can go up to a speed of 112 mph.
What does the red dot on a tire mean?
The yellow dots should be aligned with the valve stem on both steel and aluminum wheels since this is the wheel’s heavy balance point. This will help minimize the amount of weight needed to balance a tire and wheel assembly. So usually, whenever you see a yellow dot, match it up with the valve stem.
What does AT stand for on tires?
If there is a “P” on the sidewall, it stands for “passenger car.” This refers to the U.S. (P-metric) method of tire sizing. “LT” stands for Light Truck, “ST” is for Special Trailer and “T” stands for Temporary, which is primarily used for small spare tires.
What does a T stand for on tires?
H/T – means Highway Terrain. This tire is made for paved roads. Most SUVs come originally equipped with H/T tires are they are usually quiet, comfortable and long lasting. Perfect for daily urban driving. A/T – means All Terrain tire.
What does LT stand for on a tire?
LT245/75R16 108/104S. LT = If a tire size begins with “LT,” it signifies the tire is a “Light Truck-metric” size that was designed to be used on vehicles that are capable of carrying heavy cargo or towing large trailers.
What is the difference between P and LT on tires?
Well, in order to differentiate between truck and passenger vehicle tires, the letters LT and P are placed in front of the tire size. Unlike the Passenger tires, the Light Truck ones are used for carrying more loads. LT tires have a load range of 10 ply, whereas P tires only have a 4 ply load range.
Are LT tires 10 ply?
…compared to early bias ply tires. Most radial passenger tires have one or two body plies, and light truck tires, even those with heavy-duty ratings (10-, 12- or 14-ply rated), actually have only two or three fabric plies, or one steel body ply. In all cases, when changing tire sizes or converting…
