What happens during an MOT tyre check? +
During an MOT, the examiner checks that all tyres are the correct size and speed rating for the vehicle, that tread depth is at least 1.6mm across the central three-quarters, that there are no cuts, bulges, or exposed cords, and that tyres on the same axle are of the same type (e.g. not mixing radial and cross-ply). Incorrect tyre pressure is not an MOT failure but the examiner may issue an advisory.
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.
Do I need to replace all four tyres at the same time? +
No, you do not need to replace all four tyres at once unless they are all worn. It is best practice to replace tyres in pairs (both fronts or both rears) to maintain even handling. The newer tyres should always go on the rear axle for stability, even on front-wheel-drive cars. Mixing tyre brands on the same axle is not recommended but is acceptable across different axles.
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.
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.
Can a tyre blowout be repaired or does it need replacing? +
A tyre that has suffered a blowout almost always needs replacing. The internal structure of the tyre is usually destroyed by the sudden loss of pressure and the impact damage that follows. Even if the tyre appears intact, the sidewall and carcass will have been compromised. A tyre fitter can inspect it, but in the vast majority of cases a new tyre is the only safe option.
