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).
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.
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.
Should I check my tyre pressures regularly? +
Yes — you should check tyre pressures at least once a month and before any long journey. Under-inflated tyres increase fuel consumption by up to 3%, reduce braking performance, and cause uneven wear that shortens tyre life. Over-inflation reduces grip and causes the centre of the tread to wear faster. Your correct pressures are listed in the vehicle handbook and on a sticker inside the driver's door frame or fuel filler cap.
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.
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.
