At what age should tires be replaced?
Old tires are dangerous, regardless of tread depth. While there’s no federally sanctioned safety guidance on when a tire is too old to be safe, many carmakers recommend replacement at six years from the date of manufacture. Old tires have been the culprit in fatal accidents.
Do tires go bad after 5 years?
The National Highway Traffic Safety Administration (NHTSA) and official manufacturers suggest a tire is only 100% safe to use until it turns 5-6 years old. However, some admit that a tire can be operable up to 10 years if you check it for issues annually after the 5th year.
Are 7 year old tires safe?
If a shop refuses to touch your six- or seven-year–old tires, you can try another shop, which might not be so strict. The rubber trade association, as well as Michelin and Continental, said tires can be safely used for up to 10 years, provided the tread is not worn and there is no visible dry rot.
Do tires expire after 6 years?
Every tire has a birth date—the day it was manufactured—and an expiration date that is six years from that manufacture date. Most automobile manufacturers warn drivers to replace vehicle tires after six years.
How do I know I need new tires?
Place a penny head first into several tread grooves across the tire. If you always see the top of Lincoln’s head, your treads are shallow and worn. If this is the case, your tires need to be replaced. If part of Lincoln’s head is always covered by the tread, you have more than 2/32 of an inch of tread depth remaining.
Do tires go bad with age?
Tires can last for several years in storage if they are stored in the right conditions. However, many tire experts recommend replacing tires six years after their production date regardless of the tread. Old tires can be compromised in other ways when the rubber compound breaks down.
Is a 10 year old spare tire still good?
Most full-size spare tires are designed to last anywhere from seven to 10 years, according to John Paul. That said, drivers should never use a tire with visible damage, such as cracks in the sidewall, punctures, impact bulges or irregular tread wear – all of which are dangerous to drive on.
Why do tires expire?
Tires age because of a chemical process called oxidation. The oxygen particles in air cause the flexible components of a tire to harden and become brittle. In 1973, the average tread life of a passenger or light truck tire was approximately 40,000 kilometres.
How old can tires be and still be sold as new?
Investigation: Aged tires being sold as new. There are no laws or regulations prohibiting the sale of tires manufactured more than six years ago, but both safety experts and many vehicle manufacturers recommend against using any tire older than six years.
Why do new car tires wear out so fast?
The OEM tires that came with your car can’t be replaced (which is a good thing) after they’ve worn out. And they will wear out much sooner than they should. This is because virtually all auto manufacturers specify very soft rubber which means they wear out too fast.
