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.
Is it safe to drive on a slow puncture to reach a tyre fitter? +
If the tyre is only slightly low and you can maintain safe control of the vehicle, you can drive a short distance at reduced speed — no more than a few miles at 20–30mph. Check the tyre regularly as you drive. If the tyre is visibly flat, the sidewall is bulging, or the car feels unstable, do not drive at all. Call a mobile tyre fitter to come to your location instead.
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.
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.
How long does it take to fit a new tyre? +
A single tyre change typically takes 15 to 30 minutes, including removing the old tyre, fitting and balancing the new one, and torquing the wheel nuts to the correct specification. If you are having all four tyres replaced, expect the job to take around 45 minutes to an hour. Mobile fitters work to the same timescales as a garage.
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.
