When do tyres need replacing?

The only part of your car that actually touches the road.

Tyres are the single most important safety component on your car. They affect braking distance, cornering grip, aquaplaning resistance and fuel economy. And yet they're also one of the most neglected. A set of four tyres gives you a combined contact patch with the road roughly the size of an A4 sheet of paper. That's it. Everything your car does, from a motorway emergency stop to a roundabout in the rain, depends on those four small patches of rubber.

The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tread width, around the entire circumference. But that's the absolute floor. Most tyre manufacturers and motoring organisations recommend replacing at 3mm, because wet-weather grip falls off sharply below that level. Stopping from 50 mph on a wet road can take noticeably longer at 1.6mm than at 3mm, though the exact figure varies by tyre type and conditions.

Age matters too. Rubber hardens over time regardless of how much tread is left. Ultraviolet light, temperature swings and the chemicals in the compound all contribute to degradation. As a rule, get any tyre over six years old inspected annually, and replace anything over ten years old even if the tread looks healthy. The manufacture date is stamped on the sidewall as a four-digit code (e.g. 2319 means week 23 of 2019).

Reading your tyre size

What does 205/55 R16 91V actually mean?

Every tyre has a code on its sidewall that tells you exactly what size and specification it is. Once you know how to read it, buying the right replacement becomes straightforward. The code is usually in the format 205/55 R16 91V. Here's what each part means.

Getting the size right matters. A tyre that's too narrow will reduce grip. Too wide and it may rub the arch or affect your speedometer reading. Your car's handbook, the sticker inside the driver's door frame, or the current tyres themselves all tell you the correct size. When in doubt, any decent fitter will look it up from your registration.

205

Width (mm)

The tyre's width in millimetres from sidewall to sidewall when fitted and inflated. 205mm is one of the most common sizes in the UK.

55

Profile (%)

The sidewall height as a percentage of the width. 55 means the sidewall is 55% of 205mm, so about 113mm tall. Lower profiles look sportier but give a firmer ride.

R16

Rim diameter (inches)

The R means radial construction (virtually all modern tyres). 16 is the wheel rim diameter in inches. This must match your wheels exactly.

91

Load index

The maximum weight each tyre can carry. 91 means 615kg per tyre. You must never fit a tyre with a lower load index than specified by the manufacturer.

V

Speed rating

The maximum sustained speed the tyre is rated for. V = 149 mph. Common ratings: T (118), H (130), V (149), W (168), Y (186). Always match or exceed the manufacturer's specification.

Types of tyre

Budget, premium, run-flat or winter. What's the difference?

Tyre prices vary enormously, even for the same size. The difference comes down to compound technology, tread design, noise engineering and the amount of R&D behind each brand. Here's what to expect at each level.

Budget

£40-£70 per tyre

Brands like Linglong, Nankang and Roadstone. Perfectly legal, fine for low-mileage city driving and short commutes. They wear faster and offer less grip in the wet than mid-range alternatives, but the upfront saving is significant if you're watching every pound.

Best value

Mid-range

£60-£100 per tyre

Brands like Hankook, Kumho, Firestone and Falken. The sweet spot for most drivers. Noticeably better wet grip, lower road noise and longer tread life than budget options. Often the best value per mile when you factor in wear rates.

Premium

£90-£160+ per tyre

Michelin, Continental, Bridgestone, Pirelli and Goodyear. Shorter wet braking distances, better fuel efficiency, lower noise and the longest tread life. Independent tyre tests typically show shorter wet braking distances compared to budget brands. Worth it if you do serious mileage or drive in all conditions.

Run-flat

£120-£200+ per tyre

Reinforced sidewalls let you drive up to 50 miles at 50 mph after a puncture. Standard on many BMWs and MINIs that have no spare wheel. They cost more and ride firmer, but mean you're never stranded at the roadside waiting for recovery.

Winter

£60-£140 per tyre

Softer rubber compound and deeper tread designed for temperatures below 7C. In cold, wet or icy conditions they stop significantly shorter than summer tyres. Popular across Europe and increasingly common in the UK, especially in Scotland and northern England.

All-season

£70-£130 per tyre

A year-round compromise between summer and winter performance. Carry the three-peak mountain snowflake symbol for basic winter capability. Ideal if you don't want to store and swap two sets, but they won't match a dedicated summer or winter tyre at the extremes.

Warning signs

Six signs your tyres need replacing.

Don't wait for the MOT tester to tell you. Catching these early keeps you safe and avoids a fail, a fine, or both.

Low tread depth

The legal minimum is 1.6mm, but grip drops off well before that. At 3mm your stopping distance in the wet starts to increase noticeably. At 1.6mm, a car doing 50 mph needs an extra two car lengths to stop compared to a new tyre.

Uneven wear

One edge wearing faster than the other usually means your tracking is out. A worn centre strip means over-inflation. Patchy, cupped wear points to tired shock absorbers. All of these shorten tyre life and reduce grip.

Sidewall damage

Bulges, cuts or cracks on the sidewall mean the tyre's internal structure is compromised. This cannot be repaired. A sidewall bulge can blow out without warning, especially at motorway speed. Replace immediately.

Vibration through the steering

Persistent vibration at speed could be a buckled wheel, but it can also mean internal tyre damage or a separated belt. Either way it needs checking. Ignoring it risks rapid, uneven wear and a blowout.

Age cracks in the rubber

Even if the tread looks fine, rubber degrades with UV exposure and time. Small cracks between the tread blocks or along the sidewall (known as dry rot) mean the compound is hardening and losing grip. Any tyre over six years old should be inspected regularly. Over ten years, replace it regardless of tread.

Repeated slow punctures

One puncture is bad luck. Two or three in the same tyre often mean the repair is failing, the valve is leaking, or there's a nail you haven't found yet. At that point a new tyre is cheaper than another repair and recovery call-out.

The 20p test

Check your tread depth in 30 seconds.

You don't need a gauge to get a rough idea of where your tread stands. A 20p coin is all it takes. The outer band of a 20p is approximately 3mm from the edge to the start of the inner lettering. That makes it a handy, free indicator of whether you're in the safe zone or approaching replacement territory.

  • 1Place a 20p coin into the main tread grooves of the tyre, with the outer band facing down into the groove.
  • 2Check at least three points across the tread width and repeat at several spots around the circumference. Wear isn't always even.
  • 3If the outer band of the coin is hidden by the tread, you have more than 3mm remaining. You're in good shape.
  • 4If any part of the outer band is visible, your tread is at or below 3mm. Start shopping for replacements.
  • 5If the band is clearly visible all the way around, you're close to the 1.6mm legal limit. Book a fitting now, because driving on worn tyres in the wet is genuinely dangerous.

The 20p test is a guide, not a substitute for a proper tread gauge. If you're borderline, get a garage to measure with a calibrated depth gauge. They'll do it free as part of any tyre quote.

UK tyre law

The law is blunt. The penalties are steep.

1.6mm minimum tread

Across the central three-quarters of the tread width, around the entire circumference. Below that, the tyre is illegal regardless of how the rest looks. Most manufacturers mould tread wear indicators (TWIs) into the grooves at 1.6mm to make it obvious.

Up to £2,500 fine per tyre

Each illegal tyre carries a maximum fine of £2,500 and 3 penalty points. Four dodgy tyres means up to £10,000 and 12 points, which is an automatic driving ban. Police can and do check at the roadside.

3 penalty points per tyre

Three points per defective tyre. On a standard licence with 12 points before disqualification, four illegal tyres puts you over the limit in a single stop. New drivers (within two years of passing) lose their licence at just 6 points.

MOT fail for tyre defects

Tread below 1.6mm, sidewall bulges, exposed cord, cuts deep enough to reach the ply, and mismatched sizes on the same axle will all cause an MOT failure. Tyres are one of the top five reasons cars fail each year.

Insurance implications

Driving on illegal tyres gives your insurer grounds to refuse a claim. If you're involved in an accident and the investigating officer finds a bald tyre, your cover could be voided entirely. That applies to fully comprehensive policies too.

Matching axle rules

While UK law doesn't mandate identical tyres across axles, mixing radial and crossply on the same axle is illegal. Many insurers and manufacturers also specify matching sizes and speed ratings per axle. Check your handbook.

Tyres and your next service

Fitting tyres alongside a service saves time and money.

If your tyres are due and your service or MOT is coming up, bundle them in the same visit. The car is already on the ramp, the garage can check alignment at the same time, and you avoid a second trip.

Many garages offer a discount when you combine tyre fitting with a service or MOT because the shared labour time makes it efficient for them too. Less dead time between jobs means savings they can pass on.

One ramp, one visit

Fitting tyres alongside a service means no second trip and shared labour costs.

Alignment included

Most garages check tracking when they fit tyres. Combine with a service and it's often bundled in.

MOT-ready

New tyres before an MOT removes one of the top five failure categories from the equation.

Bundle pricing

Garages discount combined bookings because less dead time between jobs means better efficiency.

Common questions

Tyre FAQs

How long do tyres last on average?
Most front tyres on a front-wheel-drive car last 20,000-30,000 miles. Rears tend to last longer because they carry less load and don't steer. Driving style, alignment, road surfaces and tyre quality all move that number up or down. Regardless of tread, any tyre older than ten years should be replaced because the rubber compound hardens and loses grip over time.
Can I mix tyre brands on the same car?
You can, but you must keep the same brand and tread pattern on each axle. Mixing brands across the same axle is legal but strongly discouraged because the two tyres will grip differently under braking and in the wet. If you're only replacing two, fit the new pair to the rear axle for better stability.
Do I need to get my tracking done when I fit new tyres?
It's highly recommended. Misaligned wheels cause uneven tread wear, meaning your new tyres could scrub down on one edge far sooner than they should. Most garages offer a wheel alignment check as part of a tyre fitting package. It adds around 15-20 minutes and usually costs between £30 and £60.
What does the speed rating on a tyre mean?
The speed rating is the letter at the end of the tyre size code (e.g. the V in 205/55 R16 91V). It tells you the maximum sustained speed the tyre is designed for. T = 118 mph, H = 130 mph, V = 149 mph, W = 168 mph. You must fit tyres with a speed rating at least as high as the one specified by the manufacturer.
Are part-worn tyres safe?
Part-worn tyres are legal in the UK provided they meet minimum standards: at least 2mm of tread, no structural damage, and clearly marked as part-worn. In practice, you have no idea what that tyre has been through, whether it was run flat, kerbed hard or sat in the sun for years. For the sake of the price difference, new budget tyres from a known brand are a safer bet.
Will my car fail its MOT on tyres?
Yes, if any tyre is below 1.6mm of tread across the central three-quarters of the tread width, around the entire circumference. Sidewall damage, cuts, bulges, exposed cord or mismatched sizes on the same axle will also cause a fail. Tyres account for roughly 10% of all MOT failures.
How often should I check my tyre pressure?
At least once a month and before any long journey. Under-inflated tyres increase fuel consumption, wear the edges faster, and handle worse. Over-inflated tyres wear the centre strip and reduce grip. The correct pressures for your car are printed on a sticker inside the driver's door frame or in the handbook.
What's the difference between run-flat tyres and standard tyres?
Run-flat tyres have reinforced sidewalls that support the car at reduced speed (usually up to 50 mph for 50 miles) after a puncture, so you can reach a garage without a spare. They cost more, ride slightly firmer, and can't always be repaired after a puncture. If your car came with run-flats and has no spare wheel, you should stick with them.
