How old can tyres be before they need replacing? +
Even if the tread looks fine, tyres degrade over time as the rubber compound hardens and loses grip. Most manufacturers recommend replacing tyres after 5 years of use, and no tyre should remain in service for more than 10 years from the date of manufacture. You can check the age using the DOT code on the sidewall — the last four digits show the week and year of manufacture (e.g. 2319 means week 23 of 2019).
What should I do if I get a flat tyre on the motorway? +
Pull onto the hard shoulder as far left as possible, switch on your hazard lights, and exit the vehicle from the passenger side away from traffic. Do not attempt to change a tyre on the motorway hard shoulder — it is extremely dangerous. Move behind the crash barrier if there is one, then call a mobile tyre fitter or breakdown service. If you are on a smart motorway with no hard shoulder, stop in an emergency refuge area.
Are part-worn tyres safe to buy? +
Part-worn tyres carry significant risks. While they are legal to sell in the UK, studies have found that a large proportion fail to meet legal standards — many have been previously repaired improperly, have internal damage not visible from the outside, or are close to the legal tread limit. The small saving is rarely worth the risk. New budget tyres from reputable brands often cost only £15–£25 more and come with a full warranty.
What is the difference between budget and premium tyres? +
Premium tyres from manufacturers like Michelin, Continental, and Bridgestone consistently outperform budget alternatives in independent braking tests — often stopping several metres shorter in wet conditions. They also tend to last longer, produce less road noise, and offer better fuel economy. For a typical family car, the difference between a budget and premium tyre is usually £25–£40 per tyre, which most drivers recoup through longer tread life.
What is the legal minimum tyre tread depth in the UK? +
The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre, around its entire circumference. However, most motoring organisations recommend replacing tyres at 3mm, as braking performance drops significantly below this level. Driving on tyres below 1.6mm carries a fine of up to £2,500 and 3 penalty points per illegal tyre — so four bald tyres could mean a £10,000 fine and 12 points.
Are winter tyres worth it in the UK? +
Winter tyres use a softer rubber compound and a different tread pattern that provides significantly better grip below 7°C — not just in snow, but on cold, wet roads. In independent tests, winter tyres reduce braking distances by up to 11 metres compared to summer tyres in cold conditions. If you regularly drive in rural areas, hills, or northern parts of the UK, they can be a worthwhile investment from October to March.
