What is a 300 treadwear rating?
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. Treadwear is the easiest to decipher as it is a three-digit number that indicates how long tread on the tire will last relative to other tires. In theory and in similar conditions, a tire with a 300 treadwear rating will last three times as long as one with a 100 rating, and so on.A good tire treadwear grade is generally considered 300 or above, as per nhtsa. Tire ratings above 400 are generally preferred for long tread life. Drivers looking for performance usually opt for lower ratings between 100-300. The tire tread of these tires wear out faster but provide top-notch grip and traction.A tire with a 500 treadwear rating is expected to last approximately 50,000 miles under standard conditions. However, factors like driving style, road conditions, and vehicle type can affect actual mileage.Treadwear Grades Scores are determined in tire wear tests in closely controlled driving conditions. Since 100 is the base standard, a tire with a score of 200 should last twice as long as the standard. A score of 400 should last twice as much as the 200 scored tire.
Is 300 better than 500 treadwear?
Here’s a general guide for treadwear ratings based on driving needs: Daily Commuting: Look for a treadwear rating of 500-700 for extended durability. Performance Driving: Lower ratings like 200-300 will provide better grip but wear faster. For example, a tire with a treadwear rating of 700 may last approximately 70,000 miles. There is no real science supporting this “rule. Unfortunately, the rating that is of the most interest to consumers is the one that is the least consistent.How long will 3mm tyre tread last? The average tyre with 3mm of tread can expect around 10,000-15,000 miles before needing replaced. Make sure to check your tyres regularly though. As this will fluctuate based on your specific tyres and the factors mentioned before.For example, a tire with a treadware index of 50 will wear 2 times faster than a normal tire whereas a tire with a treadwear index of 420 will wear 4. REMEMBER: The higher the treadware index, the longer the life of the tire.A tire rated at 200 has a projected tread life of 60,000 miles. A tire rated at 50 has a projected tread life of 15,000 miles.However, a higher number for treadwear generally indicates a tire that may last longer. An “A. A. Lastly, an ” A ” temperature rating indicates the tire’s superior ability to dissipate heat.
Is treadwear 500 good?
Tires with medium treadwear are therefore excellent for everyday driving. Most all-season tires fall in this category, especially between 300 and 500 treadwear. As tread wears unevenly or becomes too shallow, rolling resistance may change—either increasing or decreasing—depending on the tire type. Tires worn beyond their optimal tread depth can subtly raise fuel consumption, leading to less mileage per gallon and lower overall efficiency.Miles driven, road conditions, driving style, maintenance and age all affect how long a tire lasts. Tires naturally wear the more they are driven and worn out tires provide reduced traction compared to those with adequate tread, especially in adverse weather conditions.
How long will 400 treadwear last?
While not even the best UTQG-rating tires can be completely trusted, the tire tread wear ratings guide is actually quite straightforward. To estimate a tread life based on treadwear ratings, you will need to multiply the number by 1000. Therefore, based on simple math, a 400-rated tire should last for 40,000 miles. A good tire treadwear grade is generally considered 300 or above, as per NHTSA. Tire ratings above 400 are generally preferred for long tread life. Drivers looking for performance usually opt for lower ratings between 100-300.The test track they use is a 400-mile loop for a total of 7,200 miles. If a tire is rated 100, it is expected to last as long as the test tire. A tire rated 200 will last twice as long, one rated 300 will last 3 times as long, and so on.Tire tread wear is measured by the treadwear grades of the UTQG. This portrays the tire’s estimated service life. For example, 200 treadwear tires will have about 20,000 miles on them. However, this estimate is not set in stone and it will vary due to external factors.If this is just a normal every-day road tire, a rating of 280 is a bit below average. The chart above may make you think you’ll get about 45-50k miles out of a set, but that estimate is largely dependent upon a slew of factors including your driving behavior, weather, road conditions, etc.A good UTQG treadwear rating is generally 300 or above, indicating the tire is expected to be worn three times, as well as the baseline tire set by the National Highway Traffic Safety Administration (NHTSA).
How many miles will 100% treadwear last?
The standard is set so that a rating of 100 is equal to 30,000 miles. The actual rating is a percentage of 30,000 miles. A tire rated at 200 has a projected tread life of 60,000 miles. A tire rated at 50 has a projected tread life of 15,000 miles. For the average set of tyres, it’s reasonable to expect that tyres last for about 40,000km. The average driver can expect their tyres to last 2 – 3 years. Drivers who treat their tyres kindly with good driving habits may be able to extend them to 80,000km while the harsher driver may only get 15,000km.So a rule of thumb (again, looking at all seasons) is to take the treadwear rating and add two zeroes, and that’s a ballpark for how many miles the tire will last. If it has a 420 rating, that’s about 42,000 miles (though probably has a warranty for 50k). If it has an 800 rating, that’s about an 80,000 mile tire.You can expect around 1,000 miles out of your tyres if they’re down to 2 mm of tread. City driving is likely to wear tyres down quicker than motorway driving.
