Tyre wear rating

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 TREADWEAR: 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 under one and a half (l 1/2) times as well on the government course as a tire graded 100 Treadwear grades as seen on the side of the tire indicate the time a tire will take to wear down; a high number shows that the tire is likely to last long. Treadwear tests take place in controlled environments. In the testing process, manufacturers fit four vehicles with the test tires and then run them in convoy concurrently

In the USA, tyre rating standards are known as The Uniform Tyre Quality Grade (UTQG), ratings. They include ratings for Treadwear, Traction and Temperature Resistance. The Tyre and Rim Association (TRA), is the US trade organization that determines and administers tyre standards across the country Every tire is rated for the amount of weight it can support, but the rating is based on an index rather than the actual weight. For example, a load rating of 92 on a typical tire for a full-size.. The treadwear grade is a comparative rating based on the wear of a tire when tested carefully under controlled conditions. For example the useful tread on a tire graded 400 should last twice as long as a tire graded 200 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. Traction and temperature.. Traction Rating The traction grade of the tires represents the grip the tire has on the road and driving surfaces. This is indicated with letters, ranging between AA, A, B and C. AA is the best rating available on the tire market. This rating is measured by the tire's ability to stop in wet weather situations

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 track. A tire graded 200 would last twice the distance on the government test course under specified test conditions as one graded 100 The speed rating of a tyre shows you the top speed that the tyre can safely be driven at. It's a legally approved limit and tyres are only rated after they've been tested in a lab. The safest top speed applies as long as the tyre isn't being driven with too much weight loaded The speed rating system was developed to help control the safe performance of tires at standardized speeds. A tire's certified speed rating is given a letter from A to Z, ranging from 5km/h (3mph) to above 300 km/h (186 mph). This rating system (see below) shows the top speed for which a tire is certified

The tread wear rating is listed as a number on the tire sidewall after the word treadwear. The higher this number, the more likely the tire will last longer. But the tests that are used to. The Treadwear Rating is a relative number, based on how the tire to be rated wears compared to a baseline tire always rated at 100. Think of it this way: a tire rated at 200 should last twice as long as the base tire; a tire rated at 400 should last four times as long If you are running VR-rated tires, they will have less rubber than comparable tires in a HR rating and will wear faster. Look at the excise tax for the comparable tires for a clue; this tax is based on the wt. of rubber in the tire,. However, different mfg. use different rubber compounds with diff. wear ability

Temperature rating is graded from highest to lowest as 'A', 'B' or 'C'. *** Treadwear: 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 A 'standard' control tyre is assigned a grade of 100 and the treadwear rates of all test tyres are compared to it. For example, a tyre grade of 200 should take twice as long as the control tyre to wear out The tire speed rating is the maximum speed tires can safely carry a load (the original weight of your vehicle plus whatever's in it) for a sustained amount of time in ideal conditions. The rating is molded on the tire sidewall, signified by a letter or two, usually after the load index number. Together, the load index and speed rating form.

  1. Under the system, a tyre's tread wear is measured under controlled conditions involving an 11,500km drive on a specified test course, and compared with a standard tyre with a rating of 100. For example, a rating of 200 indicates that the tyre should last twice as long as the standard model

Tire Wear: All tires eventually begin to experience wear. How the tire wears can be a indication of an issue with your alignment or tire pressure. Tire tread should wear evenly across the whole tire rather than on the inside or outside of the tire. AA is the best rating a tire can receive, followed by A, B, and then C. Temperature. The.

A new car tire may have a tread wear rating as low as 150, and good quality replacement tires may have a tread wear rating of 600 in some cases. You get what you pay for, generally speaking. However, these tread wear numbers can only be accurately compared within one manufacturer's model line Cheap tires also have weaker sidewall, which can easily lead to replacing the tire because of sidewall tire damage. 4. Environment. Cheaper tires are often bad for the environment. This does both apply to the manufacturer environment and the road wear environment remains. Tires have small wear bars molded into the tread grooves. When the tread is worn down to the level of the wear bars (indicating 1/32 inches of tread remaining), the wear bars become exposed and the tire should be replaced. Some manufacturers recommend replac-ing the tire when there are 2/32 or 3/32 inches of tread remaining. Al

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. So the tire rated at 400 would wear four times longer than the government's mandated tire. However, please don't link treadwear grades with your projected tire mileage Load Index - This is an assigned number corresponding to the maximum allowed load the tire can carry. For the tire above, a load index of 96 means the tire can carry 1,565 pounds, for a total of 6260 pounds on all four tires. A tire with a load index of 100 could carry 1,764 pounds. Very few tires have a load index higher than 100 The tire wear indicator, sometimes referred to as the TWI, is a small piece of raised rubber inside of a tread groove. Wear indicators are available on nearly every tire meant for consumer use, including motorcycle tires. Sometimes a triangle or the letters TWI will be located on the sidewall. These are used to help you find where the wear.

Definition of Tire Speed Ratings . A tire's speed rating is an indication, expressed as a letter code on the tire sidewall, of a speed the manufacturer expects the tire to be able to sustain over a long period of time without coming apart.This is good information to have for a number of reasons, some of which actually include the likelihood of you ever being able to sustain even the lowest of. The higher the tire-load rating, the more weight your tire can handle. However, do note that the tire load rating number itself is not the actual weight limit. For example, a tire-load rating of 105 means that these tires can handle a maximum-weigh capacity of up to 2,039 pounds (925 kilograms) The Tyre load rating is the maximum load or weight a moving tyre, at the fastest speed allowed, when properly inflated, can carry. The rating (or index) is applicable for just that one, individual tyre - and not all four attached to the vehicle. In most cases, each of the four tyres found on a vehicle should have identical load ratings
