Tyres are the only part of your car that touches the road. Despite this, they are one of the most neglected maintenance items. Here is what you need to know about tyre lifespan and when to replace them.
How long do tyres typically last
There is no fixed answer. A set of tyres on an average UK car covering around 10,000 to 12,000 miles per year will typically last between 3 and 5 years on the front axle and somewhat longer on the rear on front-wheel-drive cars.
The legal minimum tread depth
In the UK, the legal minimum tread depth is 1.6mm across the central three-quarters of the tyre, around the full circumference. Driving below this limit is illegal and can result in a fine of up to £2,500 per tyre and three penalty points on your licence.
Most tyre manufacturers and motoring organisations recommend replacing tyres before they reach this limit. Below 3mm, wet braking distances increase significantly.
Warning signs your tyres need replacing
Tread wear indicators are moulded into the tyre grooves at 1.6mm depth. When the tyre surface is level with these indicators, the tyre is at the legal limit. Also watch for uneven wear (usually an alignment or pressure problem), cracking or bulging in the sidewall (replace immediately), and unusual vibration through the steering wheel.
Age matters as well as wear
Even a tyre with plenty of tread can become unsafe with age. Most manufacturers suggest replacing tyres after 5 to 6 years regardless of tread depth. The manufacturing date is stamped on the tyre sidewall as a four-digit code: for example, 2419 means the 24th week of 2019.
Keeping tyre wear even
Check tyre pressures at least monthly and before long journeys. Correct pressures are in your car handbook and on a sticker inside the driver door. If you notice uneven wear, have your wheel alignment checked.
