All tyres will eventually need replacing.
How quickly that happens depends on various factors, such as your driving habits, where you live and how well you maintain your tyres.
You should inspect your tyres regularly – at least once a month. If you spot any of the issues below, your tyres need replacing:
Tread wear bars: most tyres have tread wear bars - bands of hard rubber that you can only see when your tread depth has gone beyond the limit for safe driving, which is generally 1.6mm.
Uneven wear patterns: you should also check your treads for uneven wear patterns that can indicate other problems with your tyres or your vehicle.
A bulge or a blister on the sidewall of a tyre. These can lead to tyre failure and are potentially dangerous.
A tyre has gone flat due to a blow out.
Lacerations, or other significant damage
Sidewall or tread punctures larger than 0.64cm. You cannot repair any punctures larger than this, and you should never repair tyres worn below 1.6mm.
In the U.S., Europe, and Japan, 90% of old or ‘end-of life’ tyres are recycled for energy recovery.
Vehicle handling may be significantly affected by a change in tyre size or type. Before replacing tyres, always consult the vehicle owner's manual and follow the vehicle manufacturer's replacement tyre recommendations.
