Tires/Life Span of tires


Hugh wrote at 2009-05-20 23:51:27
Tires DO have a shelf life!  I saw something on the news about a woman who put an unused spare tire on her jeep, and the next day when her son was driving on the highway, the tire came apart, car flipped, and he was killed.  Tires degrade whether they're being used or not.  Rubber breaks down.  Tires are unsafe if they're being used more than 6 years after their manufactured date.

I agree with the answers given BUT  I do not agree with the lifespan.

Rubber has lifespan.

Mostly it will last for 5 years the most. That is why even your car driven rarely and the thread is so good but it is more then 5 years from manufacturer date ;  it is recommended to change although human feel it is waste of money.  WHY should I?  Because it will have breaks, cuts, and on high temperature during summer on roads tire may explode or punctured.  You may reply to me via email personally to have debate but I 100% will lose to you cause you are trained by Michelin.

While tires don't have a shelf life for the purpose of refunds, they do where safety is concerned. After six years of age, problems are far more likely and several tests have been conducted to prove this.

I drive a 1998 motor home. Last year I had two tires blow out on a paved highway (temp was about 75 deg f.) These blow outs were two days apart and they were Michlins with exelent tread. when asking why they faild I was told that the normal atmosphere used to inflate them rots them from the inside out. Today they should be inflated with nitrogen t prevent this failure. I understand that COSTCO provides this service.

I to have had issues with sears not wanting to replace tires that wore out after just 19,000 miles on a tire that has a 40,000 mile warranty.  Thinking about sending a letter to the BBB.

The safe lifetime of a tire is considered to be six years from date of manufacture. It doesn't matter if they have been mounted or not. After six years they are less safe as they rubber compound has aged. Tires in hot climates have less life.  Google this if you want.

The life of a tire is six years from date of manufacture. The rubber degrades compromising the safety of the tire. If exposed to high temperatures the life is shortened. This applies to unmounted as well as mounted tires.

He is wrong, tires do have shelf-life; the only ones that do not are aircraft tires, and they go by a color coding system. EXPERT go back to the book, cause your answer is wrong.

John you may want to check your facts before giving advise.  According to  Cooper tires, America's Tire and The Tire Rack, tires do have a shelve life of 6 years and a road life (if tread wear allows) of ten years.

Need help with tire questions? I am trained by Michelin and have worked in a tire department for years, and served as the supervisor. I will answer only basic information or request. I can help you understand some tire questions on buying or just to understand tires. I may or may not answer questions about trouble or problems with tires, do to the fact that it is hard to say what is wrong with a tire without looking at the tire. Questions about tire sizes fitting your car are limited, up to 1998 at this time. All other tire questions, year does not matter.
