Realistic mileage figures, why age matters as much as wear, and the things that quietly shorten a tyre’s life.
In short: Most car tyres last somewhere between 20,000 and 40,000 miles, with front tyres on a front wheel drive car typically wearing out in roughly half the time of the rears. Age matters independently of mileage: rubber hardens and cracks over time, so around ten years is a sensible practical limit even on a tyre with plenty of tread left.
It is a frustrating question to answer honestly, because the range is genuinely wide. Two identical cars on identical tyres can be 20,000 miles apart at replacement time purely because of how and where they are driven. What is more useful than a single number is knowing what is actually eating your tread, because most of it is within your control.
Realistic mileage expectations
| Situation | Typical life |
|---|---|
| Front tyres, front wheel drive car | Around 20,000 miles |
| Rear tyres, front wheel drive car | Around 40,000 miles |
| Mostly motorway driving | Towards the upper end of the range |
| Mostly short urban trips | Towards the lower end |
| Performance or low profile tyres | Often 15,000 miles or less |
| Vans and heavily loaded vehicles | Shorter again, and load rating matters |
The front and rear difference surprises people. On a front wheel drive car the front tyres handle the steering, most of the braking and all of the power delivery, so they do far more work. This is also why a car can arrive for two new fronts having had the same rears since it was bought.
Age matters as much as mileage
A tyre is a rubber compound, and rubber does not stay the same forever. It hardens, loses flexibility and eventually starts to crack, particularly in the sidewall. A tyre that has done very few miles but has been on the car for twelve years can have poor wet grip and a weakened structure while still showing most of its original tread.
There is no legal age limit for tyres on ordinary cars in the UK, though tyres over ten years old are banned from the front axles of lorries, buses, coaches and minibuses. For a car, treat ten years as the point at which a tyre should be replaced regardless of tread, and start paying closer attention from about six years.
How to read your tyre’s age Look on the sidewall for the DOT code. The last four digits are the manufacturing date: the first two are the week, the last two are the year. A tyre marked 2321 was made in the twenty third week of 2021. Worth checking on any car you have just bought, and on a spare wheel that has never been used.
What actually shortens tyre life
- Running underinflated. The single biggest factor. A soft tyre wears its shoulders away rapidly, runs hot and uses more fuel. A monthly pressure check is the cheapest tyre maintenance there is.
- Wheel alignment out of true. Even slightly incorrect tracking scrubs rubber off one edge continuously. Kerbs and potholes knock alignment out, and around here that happens often.
- Hard acceleration and heavy braking. Aggressive driving can halve tyre life. Nothing complicated about this one.
- Short urban journeys. Constant stopping, starting and low speed turning wears tread faster per mile than steady motorway running.
- Potholes and kerb strikes. Beyond the immediate risk of damage, repeated impacts affect alignment and suspension, which then wears the tyres unevenly.
- Carrying weight. A consistently loaded car or van works its tyres harder. Check the handbook for laden pressures rather than using the standard figures.
- Standing still. A car left unused for long periods can develop flat spots and the rubber degrades without doing any miles at all.
Reading the wear pattern
Where a tyre is wearing tells you why, and fixing the cause is what stops you buying another set sooner than you should.
- Both edges worn, centre fine. Underinflation.
- Centre worn, edges fine. Overinflation.
- One edge only. Alignment or tracking out, or a worn suspension bush or arm.
- Scalloped, patchy or wavy wear. Usually worn dampers, sometimes an out of balance wheel.
- Feathered edges on the tread blocks. Typically a toe setting problem.
If you are replacing a tyre that has worn unevenly, get the alignment checked at the same time. Otherwise the new tyre will wear the same way.
How to make tyres last longer
- Check pressures monthly, when cold. Use the figures on the door pillar sticker or in the handbook, not the number on the tyre sidewall, which is a maximum rather than a recommendation. Check them before a long drive, not after.
- Have the alignment checked once a year. Or straight away after a heavy pothole or kerb strike. It is inexpensive and it pays for itself in tread.
- Rotate tyres if your handbook allows it. Moving rears to the front evens out the wear across the set. Not all cars and tyre types permit it, so check first.
- Inspect them properly every few weeks. Look for cuts, bulges, stones lodged in the tread and any change in wear pattern. It takes two minutes.
- Deal with slow punctures early. A tyre that keeps losing pressure is wearing badly and may be repairable now but not later. A proper repair to BS AU 159 costs a fraction of a new tyre.
When to replace regardless
Some things override any mileage or age calculation. Replace a tyre straight away if it has a bulge or lump in the sidewall, exposed cords, a cut deep enough to reach the internal structure, or if it has been driven on while flat. In each case the internal structure has been compromised and no amount of remaining tread makes it safe.

Frequently asked questions
How many miles do car tyres last?
Most car tyres last between 20,000 and 40,000 miles. On a front wheel drive car the fronts typically wear out in around 20,000 miles and the rears in around 40,000, because the front tyres handle steering, most of the braking and the power delivery.
How long do tyres last in years?
Around ten years is a sensible practical limit even on a tyre with plenty of tread, because rubber hardens and cracks with age. It is worth inspecting tyres more closely once they pass about six years old.
How do I find out how old my tyres are?
Look for the DOT code on the sidewall. The final four digits give the manufacturing date, with the first two being the week and the last two the year. A code ending 2321 means the tyre was made in the twenty third week of 2021.
Why do my front tyres wear out faster than my rears?
On a front wheel drive car the front tyres do most of the work. They steer, deliver the engine’s power to the road and handle the majority of braking effort, so they typically wear roughly twice as fast as the rears.
What causes uneven tyre wear?
Wear on both shoulders points to underinflation and wear in the centre points to overinflation. Wear on one edge only usually means the alignment is out or a suspension component is worn. Scalloped or patchy wear generally indicates worn dampers or an unbalanced wheel.
Does rotating tyres make them last longer?
It can, by evening out the difference in wear between the front and rear axles. Check your handbook first, because not every car and tyre type is suitable for rotation, and directional tyres can only be swapped front to back on the same side.
Should I replace all four tyres at once?
Not necessarily, but tyres should always be replaced in pairs across the same axle so that grip is even from side to side. If only one tyre is damaged and the others have plenty of tread, replacing that axle’s pair is usually the sensible approach.
