Do tires wear out at 40 k miles when the car has 40k miles on it?

Answer 1

If you bought a new car and drove it 40K miles on the original tires you did quite well in the real world. Some factory tires are quite good and might make it to 50 or even 60K, sometimes. Tire makers will claim they make 65K, 80K and even 100K tires but mostly those ratings are wild fantasies. Even the UTOG ratings for treadwear don't always mean much, tire wear is affected by lots of things, including alignment, driving habits, inflation and rotation.

Most all tires have small wear indicators built into the tread at intervals around the tire. They look like small bars inbetween the tread grooves. Some tires will even have small arrows with "TWI" on the shoulder of the tire to point out where the Treadwear Indicators are located. If your tire is worn down to that point then legally your tires are worn out and not safe. But if your tires are worn on the edges until steel belts or cords are showing, you are in even worse shape.

Answer 2

Umm, that depends on a whole lot of factors. First of all, the type of tire and the type of vehicle. Some vehicles come with OE tires that will easily go 50k miles or more, others come with tires where you can consider yourself very lucky to get 20k miles.

If your not sure if yours need replacing, drop by a tire store and have them measure the tread. They will be able to tell you how much life your tires have left.

PS

DO NOT, as several previous posters have said, go by the UTQG rating as any indication of what kind of mileage the tire is good for. UTQG ratings for wear are determined by the tire company's marketing department (I know this for a fact - I was once in a meeting with a rep from a major tire manufacturer where he asked us point blank what UTQG we retailers wanted put on a particular tire). Another example; Pirelli make two different lines of all-season tires that each has an 85k mile treadwear warranty. One has a UTQG wear rating of 720, the other has a rating of 620. Shouldn't they both have the same rating????

Answer 3

Probably Deb. If you read the UTOG wear rating on one of your tires I'm guessing the number is 340 or lower. that correlates to a 40 - 45,000 mile tire. When shopping for new tires go to tireack.com, feed in your car and the site will spit out your standard OEM tire size. From there you can shop in any one of a dozen tire brands. Open up a particular tire and under specs. A page will open with all specifications on that tire. The higher the UTOG number the longer it'll wear. Anything higher than a # 620 - 850 will last 80,000 miles.

Answer 4

It depends on the tire. Sports cars use softer tires for better handling but they wear out faster.

The best way to check is an inspection. You can do this yourself. Use the Lincoln penny test. Take the penny, flip it so that Lincoln's head is upside down. Slide it between the grooves on the tread. If you can see the top of Lincoln's head then the tread is too thin. That's about 2/32".

Answer 5

How fast tires wear depends on a number of factors - maintaining proper inflation pressure, wheel alignment, proper balancing and your driving habits. A tire rated for 40K may last longer, or not as long depending on all the above factors.

Answer 6

Most tire have a tread rating on the back of the tire. the higher the number the better the tread. Wear all depends on what you drive on, how you drive and where you live. Same as a car from the south won't rust as fast as one from the north because of all the salt used on the roads in the winter in the north. And if ya do a lot of burnouts your tires wont last as long.

Answer 7

the tires are wear out (totally) when You have......
3/16 of deep on the thread.


...I use the tires until 1/16.

Answer 8

i think your tires have an ok amount of wear on them but i wouldnt worry about it for like until it hits atleast 80k miles.
