Your tyres are the only contact between your vehicle and the road. Driving on worn or damaged tyres dramatically increases your stopping distances, reduces wet-weather grip and raises your risk of a blowout. Here are the five clearest signs you need to act now.
1. Tread Depth Below the Legal Limit
UK law requires a minimum tread depth of 1.6mm across the central three-quarters of the tyre. A tyre worn to this level should be replaced immediately. Most safety experts recommend replacing tyres at 3mm, as wet braking performance degrades significantly between 3mm and 1.6mm. Use a 20p coin to check — if the outer band of the coin is visible when inserted into the tread groove, your tyre is at or below the legal minimum.
2. Visible Cracks or Bulges on the Sidewall
Cracks in the sidewall indicate the rubber is degrading, which can lead to a sudden blowout. A bulge or bubble in the sidewall means the internal structure of the tyre has been damaged — this tyre is at serious risk of failure and should not be driven on. Call us immediately for a mobile tyre replacement.
3. Persistent Vibration or Pulling to One Side
If your vehicle pulls to one side or you feel unusual vibrations through the steering wheel, this could indicate uneven tyre wear, a damaged tyre or a wheel alignment issue. Both pulling and vibration should be assessed promptly by a professional.
4. Frequent Loss of Tyre Pressure
If you find yourself regularly topping up tyre pressure on the same tyre, it is likely you have a slow puncture. A nail, screw or damaged valve can cause gradual air loss. This should be inspected and either repaired or the tyre replaced.
5. Tyres Over Six Years Old
Even if a tyre appears undamaged, rubber degrades over time. Most manufacturers recommend replacing tyres over six years old regardless of appearance. Check the four-digit DOT code on the sidewall — the last four digits indicate the week and year of manufacture.
