How long does a tyre last? What are the basics? A few milestones and tips: 1- Keep five years in mind After five years or more in use, your tyres should be thoroughly inspected at least once per year by a professional. How to check the manufacturing date Look for the DOT number on your sidewall. What damages tyres? Do I need to change now?
Any lower, your tyre is no longer roadworthy. Do not perform any tyre repairs because it is illegal to use and must be replaced. Your tyre is exposed to all kinds of obstacles and debris out on the road that can cause severe damage.
These include potholes, kerbs, various sharp objects like rocks, branches, small stones, old cans, nails, and more. They can puncture, cut or rip your rear and front tyres and even deform their shape. If you spot any large - or even small - visible perforations, get a tyre professional to check your tyre ASAP. Don't forget to unmount the tyre and check inside as well.
If it is badly damaged, you need immediately get new tyres fitted. There are instances when tyre tread wears down in unusual ways. Either just at the edges, or the centre gets bald first or tyre wear occurs in patches or random chunks throughout the tyre circumference. These are possible signs that you are driving with too much or too little air; the wrong tyre pressure in general.
There could also be underlying issues with your vehicle, like bad wheel balance and suspension problems or more. It's a good idea to get a mechanic to inspect your cars and replace your tyres. But how old is "older" exactly? Tyres don't have official expiry dates - only dates when they were manufactured DOT. The usable life of a tyre is not something that one can predict - no matter the date of production.
Tyres experience the most stress when in use, on the trail or the road, and not while sitting in storage. The following factors affect the life of a tyre much more than its production date:.
As a precaution, if your tyres have been in use for more than five 5 years old, get them inspected once a year.

The first and most obvious aspect of tyre safety is tread depth. And by this we mean the deepness of the main grooves that cover the circumference of the tyre. From new, the depth of tread will be around 7mm, while the legal limit is 1. Most tyres have tread wear indicators, which are hard, raised bars at the bottom of each groove. When the tread is level with these bars then the tyre will have reached the legal limit.
However, it is unwise to rely on these alone as uneven tyre wear is a common problem. Poor wheel alignment or worn suspension can produce uneven wear to the inside or outer edge of the tyre, while leaving the tread bar intact. To check the condition, run a 20p coin along the tread - the outer edge of the coin is 1. As mentioned, the legal limit for tread depth is 1. However, owing to developments in tyre compound technology, some manufacturers are beginning to dismiss this advice.
Michelin, for example, claims that its tyres are designed to provide as-new performance all the way to the 1. The French tyre maker is also campaigning for EU tyre ratings to be changed to reflect worn performance for all tyres at 1. Whether you replace at 1. But it's important to note that tyres that are near or on the legal limit can be more susceptible to aquaplaning, owing to the fact there is less tread depth to allow for water dispersion.
For example, a tyre with 1. As well as becoming worn, tyres are susceptible to damage. Unlike a puncture or excessive wear, damage can be difficult to spot, with no immediate impact to the car's handling.
