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.
What does the TPMS warning light mean? +
The TPMS (Tyre Pressure Monitoring System) warning light indicates that one or more of your tyres has dropped below the recommended pressure. This could be caused by a slow puncture, a change in temperature, or simply natural air loss over time. Do not ignore it — under-inflated tyres increase braking distances and can overheat at speed. Check your pressures at the nearest petrol station or call a mobile tyre fitter.
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.
How do I read my tyre size? +
Your tyre size is printed on the sidewall in a format like 205/55R16 91V. The first number (205) is the width in millimetres, the second (55) is the aspect ratio as a percentage of the width, R means radial construction, and 16 is the wheel diameter in inches. The number after (91) is the load index and the letter (V) is the speed rating. Your vehicle handbook and the sticker inside the driver's door frame show the correct size for your car.
What are run-flat tyres and can any fitter work on them? +
Run-flat tyres have reinforced sidewalls that support the weight of the car even with no air pressure, allowing you to drive up to 50 miles at 30mph after a puncture. They require specialist fitting equipment and a TPMS reset after replacement. Not all garages can work on run-flat tyres, but most professional mobile fitters and tyre centres are fully equipped. Run-flat tyres are typically 20–40% more expensive than standard equivalents.
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.
