This is because tires are made mostly of rubber, and rubber degrades with age. Sunlight, heat, ice, and general wear and tear can accelerate the breakdown of a tire.
Why do tires age dangerously?
Tires age dangerously because of a chemical process commonly referred to as oxidation, which simply means that as the tire components are exposed to oxygen, the oxygen particles cause the flexible components of a tire to harden and become brittle. Over time, the tire will simply fall apart under normal stress, just like an old rubber band.
Why do tires expire?
A tires service time expires because of the rubber aging, as the material is always exposed to oxygen that makes the particles become harder and less flexible. As a result, the rubber starts to crack outside and inside, which may cause tread or steel cord separation and complete tire failure.
What happens if you leave tires outside?
Furthermore, tires stored outside are even worse off. For instance, the sun alone can do a lot of damage to a tire. If you leave a tire sitting out where the sub reaches it, the rubber on the upward-facing side will quickly dry out. For this reason, we don’t recommend leaving tires out for very long.
What happens if a tire is under inflated?
A tire without enough air to carry the load is considered “under-inflated”. This is bad because it causes a lot more stress on the tire than it was designed for. A tire carrying a load greater than it was designed for is considered “overloaded”. Just like the under-inflated tire, it’s subject to higher stresses than it was engineered for.
Can you use 20 year old tires?
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.
Are 7 year old tires still good?
Some automakers suggest that tires be replaced as soon as they turn six years old. Some tire experts contend that tires can last anywhere from six to ten years if they’re stored and cared for properly. We recommend replacing tires aged 6-10 years, no matter how much tread remains.
How long are tires good for?
The other part is how old the tire actually is. Most tires are good for six years from the date of manufacture. So, if you get a tire that’s 2-years old, you only have four years until you should replace it. That’s even for tires that have a warranty for up to ten years.
Is it safe to replace a tire that’s 6 years old?
A tire that’s 6 years old or older isn’t safe and should be replaced, regardless of wear. People usually rely on a tire’s tread depth to determine when to replace it. But tire age is critical, too.
Are old tires dangerous?
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.

How often should I replace my car’s tires?
Originally Answered: My car’s tires are 7 years old. However, they have low mileage (20,000 miles). Should I replace my tires? Visually inspect them periodically for cracks along the sidewall and where the bead seats. Dry rotting is a concern even if there is low mileage on the tires. Good idea to check tread depth too while you’re at it.
How old are bad tires?
Most auto manufacturers recommend replacing tires over six years old regardless of tread depth. Some tire manufacturers like Michelin and Continental give a 10-year limit. As rubber compounds age, they deteriorate and become weaker like other rubber and plastic components on your car.
Is it too old for tires?
Tire manufacturers suggest replacing tires that are six years old. Anything more than that is considered too old for tires. However, some manufacturers claim their tires to be usable for ten years. And more than that, it is too old even if the tire treads are in good condition. The answer here may make you ask a lot of questions.
Are 20 year old tires safe?
Most experts agree that 20 year old tires are not safe. While the rubber may not have deteriorated to the point where it is falling apart, it is likely that the treads are significantly worn down. This can cause a number of problems, including decreased traction and increased risk of blowouts.
What is the tire age limit?
Tire Age Limit Law Most carmakers have a tire age limit of six years from the date of manufacture. That means if you have a set of four tires that are more than six years old, you should replace them. The rule of thumb is that tires begin to deteriorate as soon as they’re made, so it’s important to keep an eye on their age.
How does tire age affect driving safety?
Tire age is an often-overlooked factor that can drastically affect driving safety. Drivers usually gauge the life of their tires by the amount of tread it has left, rarely taking into account the effect age has on them. Just because your tires have tread left doesn’t mean they are safe.
Can tires sit for a year?
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.
How long do tires sit before they go bad?
Tires can sit between 6 and ten years before they go bad. Tires get worn out when you drive your car often, but they can also get worse when your car sits idle for a long time or if you have stored spare tires in your garage. On your car, the tires will lose air pressure and develop flat spots, cracks, or bubbles.
How often should you change your tires?
If you drive more, you should rotate the tires at least twice a year. In most cases, manufacturers recommend you change the vehicle oil after every 7,500 miles or after six months.
When should you take your car tires for service?
Whether you leave your car parked for a few weeks, months, or years, it is best to take the tires for service. If you leave the car tires sitting around, they will develop cracks on the internal and external surfaces. These are usually due to warm conditions that lead to the expansion of the tire.
How long do tires last in the garage?
Tires will age whether you use them or not, and stored tires will get damaged quickly if you store them incorrectly and fail to use them within six or ten years. When you store tires in your garage, the exposure to oxygen will make them hard and less flexible, leading to cracks.
Are 5 year old tyres OK?
All tyres (including spare tyres) more than ten years old should be removed from service and replaced with new tyres.
Is it safe to use a 5 year old tire?
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. What is the maximum age of a tire?

How old are your tires?
You didn’t tell us how much tread is left, which is one important factor. As for the age, your tires were most likely manufactured in 2004, which makes them seven years old, not five. There’s a code on them that will tell you for sure. Tire Rack’s web site has one or two articles about replacing tires due to age, so you should look for those.
Do tires get harder with age?
The lifespan of an average tire is six years, regardless of mileage. Once tires hit that age, the rubber compound begins to harden, and the rubber is more likely to crack. It also doesn’t grip the road surface the way it did when it was new.
Do tires get hard with age?
, Casting Director and Assistant Director. Lifelong car guy. Tires do start to get hard with age but ozone and exposure to heat, cold, weather can accelerate the deterioration of rubber. A properly stored tire can last quite a long time, decades even, but it will still experience a gradual hardening of the rubber compounds.

Five year old tires better be OK … mine are 10 years old. Recent bulletins from the tire industry indicate that tires degrade simply due to time. The age of a tire is important even if the tire is unused. There some disagreement over how to best express this age limitation, but my take is:
When should I replace my tires?
Generally, there are two different factors that impact when to replace tires: wear and age. Tire Wear: All tires eventually begin to experience wear. How the tire wears can be a indication of an issue with your alignment or tire pressure. Tire tread should wear evenly across the whole tire rather than on the inside or outside of the tire.
How old is an unused tire?
New buyers tend to think that the age is determined from the day they buy the unused tire. However, even if they are purchasing the tire newly from the shop, they still need to check the manufactured date.
