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 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
Welcome to Tyre Reviews. Tyre Reviews is the leading source of independant tyre information in the world. Every year, Tyre Reviews conducts detailed summer, all season and winter tyre tests, which can be found in the tyre test section. The Tyre Reviews website also has over 4 billion miles of tyre reviews covering more than 3000 different tyre patterns, and has databased over 400 expert tyre. Most states and tire manufacturers consider tires to be bald when one or more of their grooves are worn down to 2/32. So, if you start with a new tire tread depth of 10/32, the actual usable tread depth is 8/32 In this case it is possible to calculate the appropriate speed rating with a formula. Wear rating. The treadwear is a 3 digit comparative rating. It is part of Uniform Tire Quality Grading standard. Metric to USC tire conversion chart. R15. 215/75/15 27.7x 8.5 225/70/15 27.4x 8.9 225/75/15 28.3x 8.9 235/75/15 29.0x 9. Better Wear for Your 245/35-20 Tire record of treadwear, while offering a 420 treadwear rating and are priced at less then $140* per tire. Each tire has its own unique strengths. For example, the Ecsta 4x has great steering response, the Ventus V4 ES H105 has a directional tread design for emphasis on hydroplaning resistance and th
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 . 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 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
. *** 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.
Cupping: Tire has worn unevenly so that there are high and low ridges in the tread pattern. Wear Bars: Tire was worn to the point where the manufacturer recomends the tire be replaced; Cords: Tire was worn past all the rubber and metal belts are showing; Street: Tire is used for shorter trips, around town riding and commuting Tire load & speed ratings. Every tire has a speed rating and a load rating. The speed rating gives the max speed the tire is built for while the load rating represents the max weight of the automobile. In most cases, even the most basic tires have a speed rating around 118 miles per hour and a load rating that suits most vehicles People usually rely on a tire's tread depth to determine when to replace it. But tire age is critical, too. A tire that's 6 years old or older isn't safe and should be replaced, regardless of wear Tire wear bars, also known as tread wear indicator bars, are incredibly useful when it comes to assessing the condition of your tires in regards to wear. They're one factor that'll help you assess when you need new tires and if your current tires meet the legal tire tread depth requirements. If you're curious about what wear bars are.
All-Season Comfort: Bridgestone Turanza Quiettrack. Courtesy Tire Rack. This class of all-season tires delivers maximum comfort and quietness. Bridgestone says there's a 20 percent improvement. Maximum load ratings denoted in pounds or kilograms are also included on the sidewall of the tires. Current load indexes used for cars and light-duty trucks range from 70 to 110, or 761 to 2337 pounds respectively. The higher the load index number, the greater the tire's load-carrying capacity: 71 = 761 pounds or 345 kilograms You can also use the tire tread wear indicator as another method for how to check your tire tread. You can find the tread wear indicator less than an inch (2/32 of an inch) from the bottom of the tread groove. When the tread wears down to become even with this level, the tire should be replaced A tire with a treadwear rating of 800 should theoretically last about twice as long as a tire with a treadwear rating of 400. A longer life tire will be designed with a harder rubber compound to withstand wear better. Traction. Unfortunately, while a harder compound tire will last longer it will do so at the expense of some traction. The values succeeding the forward-slash consists of the aspect ratio, tire construction, tire diameter, tire load index (98), and tire speed rating (T). Using the same example above, 65 is the aspect ratio of the tire while 17 is the tire diameter (in inches). Aspect ratio, also known as the tire profile measurement, indicates the thickness of.
Temperature Temperature resistance indicates how a tire mainly performs in high-speed situations. The temperature ratings are A, B and C. Tires with a rating of A will be able to perform at speeds above 115 mph, while tires with a B rating are able to perform at speeds between 100-115 mph. Grade C tires can perform between 85-100 mph. Temperature resistance grading is performed in a laboratory. Treadwear: The wear rate of a tyre. The higher the number, the better the treadwear compared to other tyres in the test. For example, the wear rate of the Bridgestone Potenza RE003 is 220. Traction: The ability of a tyre to stop on wet payment. This rating carries a code of, A, B, or C, with A signifying the highest traction efficient
Ply ratings identify the load carrying capacities of a tyre in terms of plies. Ply rating originally referred to the number of cotton layers used to strengthen a tyre's casing. Today, when tyres are labelled 10-ply for example, they are no longer actually constructed of 10 individual layers of cotton, but they do offer the equivalent strength When analyzing the best tire brands, take a close look into the tire reviews and ratings of these Pirelli models before pulling out your wallet. 9. Toyo. Toyo is one of the top tire companies on the market. Founded in Japan in 1945, the superior quality at mid-range price points have been a huge factor in building the brand's reputation Tyres with this rating are the quietest tyres and can be considered low noise tyres. 2 bars - Tyres with 2 bars comply with both current legislation and the new, tighter rules. 3 bars - 3 bars indicate that the tyre meets with current legislation only
MOT Test of Tyre condition The reason for failure with respect to tyre wear is: The grooves of the tread pattern are not at least 1.6mm throughout a continuous band comprising: the central three-quarters of the breadth of tread around the entire outer circumference of the tyre Treadwear is a government-required rating that is meant to tell consumers how rapidly a tyre will wear down. In basic terms the larger the treadwear number the greater the tyre's lifespan. A tyre with a treadwear of 600 should last twice as long as a tyre with a 300 tread wear rating In Australia, the only markings required on a tyre sidewall are as follows: Tyre Size, Series, Rim Size, Load and Speed Rating/Symbol. Serial No. - date code (when tyre was built; week, month, year) Details of construction showing tyre size, radial, tubeless or tubed. On the sidewall of a tyre you will notice a number codes and markings which. Ply rating is an index of tyre strength used to identify a given tyre with its recommended maximum permitted load when used for a specific service. It does not necessarily represent the actual number of plies in a tyre. Common ply ratings are 2, 4, 6, 8, 10 and 12. Commercial (eg truck) tyres often have a ply rating rather than a load index Tread wear indicators on the tyres. Tread wear indicators show the status of the tyre's tread depth. Dimension designation for wheel rim. Wheel and rim dimensions are designated in accordance with the examples in the table below. Minimum permitted tyre load index and speed rating for tyres
We have customer ratings and reviews for every type of tire and in any driving situation— all-season tires, touring tires, winter tires, all-terrain tires and more. Look for these ratings when searching for products to find the best match for your vehicle. Categories for review include: Ride Comfort. Cornering/Steering (handling Instead, individual tire manufacturers are allowed to establish their own ratings for their tires - though, in fairness, they do all use the same standard process. How Treadwear Rating is Established. Basically, tire manufacturers use a test tire as their standard, which is run on a vehicle on a course that is a 400-mile test track The rating can go up to 650-700 and even higher for harder tires that wear longer yet provide rougher ride. The test itself is a 400-mile test loop that a vehicle convoy runs (with both test tire and Course Monitoring Tire (CMT) mounted) for 7,200 miles Tyre Tread Wear Rating Chart Source : kapodistrias-tyres.com.cy. The really first action for making your chart is to choose the data you desire to chart. With regard to look and function, the doughnut chart is rather like a pie chart. Doughnut charts are best utilized while the variety of things in your table is on the minimal side Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high. Too much pressure can cause the contact patch to shrink and the center of the tire to carry the entire load. Under-inflated Tires. Tire tread wear on the edges of a tire will typically indicate inflation pressures are lower than specified
The numbers give the load rating for the tire, while the letter indicates the speed rating. Using P215/65R15 85H as an example, the 85 gives the load index, also called the tire ply rating, and the H is for the speed rating, which tells you the maximum speed at which you should use the tires. This speed ranges from 3 mph to 186 mph For example, the economic values (wear, fuel consumption) are in contradiction with the grip. If a tire with low rolling resistance inevitably has some problems with adhesion. Here you will find the tire with the best compromise, because our comfort search allows you to filter the products according to the partial ratings of tire tests. First. 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.
Latest Goodyear EfficientGrip Performance Reviews. First note, these tyres have been rotated 2 times. The grip and handling are great, slightly decreased on wet roads, however very stable. Those tyres wear very well, but from my experience needed a bit more pressure (0,5 bar above car manufacturer recommendation) 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 wear one and one-half times as well on the government course as a tire graded 100. The relativ As their tyres have a good balance of wet and dry grip, touring and travelling drivers tend to be more inclined to purchase Goodyear tyres. Overall, reviews on Goodyear tyres seem to be consistent in that their specialised dry grip and handling tyres are very good and slow to wear

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 tire manufacturers recommend replacing the tire when there are 2/32 or 3/32 inches of tread remaining, befor If the tyre can carry the maximum permitted axle weight of the vehicle, these vehicles can use tyres with a lower speed rating tyres up to 70mph as follows: tread wear indicators, or features.
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
