Tire Longevity
Question
How long should the original tires on my vehicle last?
Answer
Tire life is affected by many factors including maintenance services such
as wheel alignment, tire rotation and proper inflation pressure as well
as driving habits. It can also vary due to differences in climates and
road conditions. To increase the longevity of the tires on your vehicle,
it is recommended that you maintain your vehicle and tires according to
the recommendations listed in your Scheduled Maintenance Guide or Owner's
Manual Supplement.
The Department of Transportation ( http://www.dot.gov ) establishes a treadwear grade for tires based on its comparative
wear rate when tested under carefully controlled conditions. As an example,
a tire with a grade of 300 should last twice as long as a tire with a
grade of 150 on the government test course. However, the actual mileage
your tires last depends on the conditions of their use and maintenance.
The treadwear rating for your tires can be found on the sidewall of your
tires. Also, for a comprehensive list of treadwear ratings from the Department
of Transportation, you can view the Uniform Tire Quality Grading Report
on their website (http://www.nhtsa.dot.gov/cars/testing/UTQG/
).
