"How long should my tyres last?" doesn't have a single number for an answer — and treating it as though it does can be misleading. Tyre life depends on a combination of factors specific to your vehicle and how it's driven, not a fixed mileage that applies to everyone.
Why there's no single figure
Tyre life varies with the vehicle itself, the tyre type fitted, the drivetrain (front, rear or all-wheel drive puts different demands on different tyres), the load it regularly carries, tyre pressure, wheel alignment, the road conditions it covers, any damage it picks up along the way, how well it's maintained, and driving style. Two identical cars can wear through tyres at noticeably different rates depending on these factors alone — which is why a single "expect X miles" figure, even a well-intentioned one, doesn't hold up in practice.
What actually shortens tyre life
Under- or over-inflated tyres wear unevenly and faster than correctly inflated ones. Poor wheel alignment causes uneven wear, often concentrated on one side or edge of the tyre. An aggressive driving style — harsh braking, rapid acceleration and hard cornering — increases wear noticeably compared with smooth, steady driving. Carrying heavy loads regularly adds strain. Rough or pothole-damaged road conditions can cause both accelerated wear and physical damage, and any damage a tyre picks up can shorten its safe working life regardless of how much tread is left. Routine maintenance — checking pressure, watching for uneven wear, keeping alignment in check — catches most of this early. None of these affect every vehicle equally, which is exactly why following your own vehicle and tyre manufacturer's guidance matters more than a general rule of thumb.
Age matters as well as mileage
Tyre rubber changes over time regardless of how many miles have been driven, so even a tyre with plenty of tread left can be due attention if it's old, has been stored badly, or shows cracking on the sidewall. A visual check for cracking, perishing or bulges is worth doing alongside checking tread depth — age-related deterioration isn't something mileage alone tells you about.
The UK legal tread depth requirement
By law, car tyres must have at least 1.6mm of tread depth across the central three-quarters of the tyre, around its entire circumference. This is a legal minimum, not a target — many tyres are less effective in wet conditions well before they reach 1.6mm, and grip in the rain and braking performance both decline as tread wears down. Replacing a tyre before it reaches the legal minimum, rather than waiting until it does, is generally the safer approach.
When to replace, not repair
Whether a tyre should be repaired or replaced depends on its condition, the location and size of any damage, its age, and whether it still meets the legal tread requirement — not a fixed rule that applies to every tyre the same way. Cracks, bulges, sidewall damage or uneven wear are all reasons to have a tyre looked at rather than waiting to see how it performs. A physical inspection is the only reliable way to know whether a specific tyre needs replacing; we're not able to make that call from a description alone.
Getting an honest assessment
If you're not sure whether your tyres need attention, we'll assess them on-site and explain honestly what's needed rather than assuming the more expensive option. See our tyre replacement service for details, or our puncture repair service if the damage turns out to be repairable.
