How long is the typical life of new tires?

Question

Is there a length of time or number of miles that they should last?

Answer 1

No such thing. There are all kinds of different tires out there with different characteristics - some are engineered for long wear, others are engineered for precise handling and traction (wear faster)

In the U.S. tires are required to wear a UTQG (Uniform Tire Quality Grade) rating for treadwear. This is a 3-digit number (example: 300 or 450 or 720 or whatever). While generally the higher this number the longer the tire should last, in reality the standards for determining this number are so lax that it is completely useless. The reality is this number is determined primarily by the tire manufacturers marketing department, not rigorous testing. You can ignore it.

For most applications tires are available which carry a treadwear warranty from the tire manufacturer. This is the only really reliable guide to how much mileage any particular tire might get. Pirelli for example warrants its new P4 Four Season tire to last for 85,000 miles with regular care. An inexpensive, entry level tire might have a much lower treadwear warranty - perhaps only 30-40k miles - or no treadwear warranty at all. High performance, ultra high performance and some types of light truck tires also frequently do not have a treadwear warranty.

Sorry the answer is not as concise as you were probably hoping for but there is no simple answer to your query.

Answer 2

Each brand and model of tire is different.

All tires have a treadwear number on them. The larger the number, the longer the tires will typically last.

There are two other grading method for tires, temperature and traction. These are rated A,B,C. Where an A = Excellent and a C=Average

So a Temperature rating = A is a tire that can handle higher temperatures that a C rated tire.

All these factors determine the typical life of a new tire.

Most modern day tires last between 30K - 70K and manufacturers will warranty their tires typically to those mileages based on proper care and maintenance.

Answer 3

The biggest factor in the lifespan of a tire is how the car is driven. If you drive aggressively, hard cornering, braking and acceleration will wear tires very quickly.

Driving with tires not inflated properly will also impact their lifespan.

Occasionally, the type of car will play a factor - the Acura NSX has a very aggressive wheel camber and the car will eat a set of tires in about 3000 miles.

Under normal conditions, you should be able to make a set of tires last at least 50,000 miles

Answer 4

Depends on the grade of tire Range from 30 to 70k miles & up to seven years

Answer 5

Depends on the tire and how many miles are put on while the tires are moving faster than the car.
