Tyres

Tyre Condition

Your tyres are the only point of contact between your vehicle and the road — roughly the size of a shoe sole per tyre. Their condition is crucial to safety.

  • Check sidewalls for cuts, cracks, or bulges.

  • Ensure tread depth meets the legal minimum: 1.6 mm across the central three-quarters of the tread and around the full circumference.

    • It’s safer to replace tyres before they reach this limit.

  • Have wheel alignment, balance, suspension, and brakes checked regularly — uneven wear may indicate a fault.

  • Remove stones, glass, or debris from the tread.

Penalties for faulty tyres include fines, licence endorsements, and possible disqualification.

 

Reducing Tyre Wear

  • Check pressures regularly (at least once a week).

  • Avoid potholes and rough surfaces — slow down if unavoidable.

  • Do not hit or scrape kerbs while parking; this can cause sidewall damage or affect wheel alignment.

  • Drive smoothly — harsh braking, fast cornering, and high speeds increase wear.

Tyre Pressure

You can’t accurately judge pressure by sight alone.

  • Check pressures when tyres are cold.

  • Don’t forget the spare tyre and replace valve caps after checking.

  • Refer to your vehicle handbook for correct pressures, which may vary depending on load or speed.

Under-inflated tyres:

  • Increase fuel consumption.

  • Lengthen stopping distances.

  • Cause excessive edge wear.

Over-inflated tyres:

  • Reduce grip and stability.

  • Increase the risk of skidding.

  • Cause centre tread wear.
