When should you replace your car tyres?

Your tyres are one of the most important safety components on your vehicle. They’re the only contact between your car and the road, and they play a major role in braking, steering and handling — something every driver in Carlisle and Cumbria notices on wet, icy or gritted winter roads.

But how do you know when your tyres need replacing?

There’s no specific mileage at which every tyre must be changed. Tyre life varies with mileage, driving style, road conditions, tyre pressures, wheel alignment and the overall condition of the vehicle. That’s why regular checks matter.

Check your tyre tread

For cars, light vans and light trailers in Great Britain — which includes both Cumbria and Dumfries & Galloway — the legal minimum tread depth is 1.6mm across the central three-quarters of the tread and around the entire circumference of the tyre.

However, waiting until your tyres reach the legal limit isn’t good practice. Tread depth has a big effect on grip in the rain, and Cumbrian weather gives tyres plenty of work.

Check your tyres regularly for both tread depth and general condition. If you’re unsure, have them inspected by a qualified professional.

Look for cuts, cracks and bulges

Tread depth isn’t the only thing that matters. When checking your tyres, look for:

  • Cuts
  • Cracks
  • Bulges
  • Sidewall damage
  • Objects stuck in the tyre
  • Excessive or uneven wear
  • Signs of deterioration

A tyre can have plenty of tread left and still be unsafe if it has significant damage. Potholes and kerbs on rural roads are a common cause of sidewall damage and bulges.

Uneven tyre wear can point to another problem

If one part of the tyre is wearing much faster than another, the tyre may not be the only problem.

Uneven wear can be linked to incorrect tyre pressures, wheel alignment, braking or suspension faults. GOV.UK advises having faults that cause excessive or uneven tyre wear corrected as soon as possible.

Replacing the tyre without fixing the underlying issue could mean the new tyre develops the same problem. Our servicing and repair team in Carlisle can check the cause as well as the tyre.

Check your tyre pressure

Correct tyre pressure is important for safety, handling and tyre wear.

The Highway Code advises checking tyre pressures weekly, before a journey and when the tyres are cold. You’ll normally find the correct pressure for your vehicle in the handbook or the manufacturer’s information.

Incorrect pressure can affect braking and steering and may cause abnormal tyre wear. It’s especially worth checking before a long journey — for example heading south on the M6 or north on the A74(M) — and when carrying extra passengers or luggage.

What about a puncture?

If you get a puncture, don’t just keep driving.

Deal with a flat tyre as soon as it’s safe to do so. Driving on a flat or badly damaged tyre can cause further damage and may make the vehicle unsafe.

GOV.UK advises that you should only change a flat tyre if you can do so without putting yourself or others at risk. Otherwise, contact a breakdown service.

This is where mobile tyre fitting is particularly useful.

When should you replace your tyres?

A tyre may need replacing if it is:

  • Below the legal tread requirement
  • Damaged
  • Showing significant cracks or deterioration
  • Bulging
  • Unevenly worn
  • Continually losing pressure
  • Otherwise considered unsafe

The replacement tyre should be suitable for your vehicle and correctly fitted. If you’re unsure, a professional inspection is the safest way to decide whether a tyre can still be used.

Mobile tyre fitting in Carlisle and across Cumbria

Tyre problems rarely happen conveniently outside a tyre shop. You might get a puncture at home, at work, at the roadside or halfway through a journey.

With mobile tyre fitting, a technician comes to your location to assess the problem and, where appropriate, repair or replace the tyre on the spot — so you don’t have to drive a potentially unsafe vehicle to a garage.

G&B Automotors provides 24/7 mobile tyre fitting across Carlisle, Wigton, Penrith, Lockerbie and Dumfries. We supply premium, mid-range and budget tyres for cars, vans, 4x4s, commercial vehicles, motorhomes and vehicles up to 7.5 tonnes. If the vehicle can’t be fixed at the roadside, our vehicle recovery service can take it to our Carlisle garage.

Absolutely brilliant service from G&B Auto Motors. We were stranded on the motorway on a Friday evening with no roadside recovery cover and were expecting an absolute nightmare, but they couldn’t have been more helpful. Ben arrived really quickly, got the vehicle picked up without any fuss, and were so lovely and professional throughout. They even went above and beyond by dropping us off at the train station afterwards so we could carry on with our journey. The price was incredibly reasonable too, especially considering the circumstances and how last-minute it was. Genuinely couldn’t recommend them highly enough. Fast, reliable, professional and just really decent people when we were in a difficult situation. Thank you so much!

An absolute lifesaver! My van gave up on me in the middle of the street, but thankfully I found this amazing mechanic. He arrived quickly, diagnosed the problem, and repaired the van roadside so I could get back to work. Exceptional customer service, fair pricing, and a top-class professional. Thank you so much for your hard work!

We cannot praise enough the service provided to us by G&B Automotors Ltd. We arrived at the garage having suffered a blowout tyre while travelling north on the M6. We were given immediate attention on arrival, the temporary tyre was removed and a new tyre fitted - all within little more than 30 minutes and at a very reasonable price. Each member of staff treated us very courteously.
