Tyre Safety
The Essential Guide to Tyre Maintenance & Road Safety
Maintaining tyres is a critical aspect of vehicle ownership that directly impacts braking distances, steering precision, and overall road safety. Understanding how to perform basic checks ensures that a vehicle remains roadworthy and operates efficiently. This guide outlines the essential safety standards and maintenance routines every driver should follow to identify potential issues before they become hazardous.
Check tread depth
Stay above the legal minimum and replace earlier for better wet grip.
Check pressures monthly
Check cold tyres to prevent uneven wear and handling issues.
Inspect sidewalls
Bulges and deep cuts can signal structural failure.
UK Legal Tread Depth Requirements
The legal minimum tread depth for passenger cars in the UK is 1.6mm across the central three-quarters of the tyre. However, safety performance—particularly in wet conditions—diminishes significantly as tread wears down. Many experts recommend considering a replacement once the tread reaches 3mm to maintain optimal grip.
Monitoring Tyre Pressure
Correct tyre pressure is vital for maintaining the structural integrity of the tyre and ensuring even wear. Both under-inflation and over-inflation can lead to unpredictable handling and increased fuel consumption.
- How often: Tyre pressures should be checked at least once a month when the tyres are "cold."
- Where to find it: The recommended PSI or Bar settings can typically be found in the vehicle's handbook or on a placard located on the driver’s door pillar.
Identifying Structural Damage
Beyond tread wear, visual inspections are necessary to spot external damage. Drivers should look for sidewall bulges, deep cuts, or exposed internal cords. A bulge typically indicates that the internal casing has failed, often as a result of an impact with a pothole or kerb.
- Bulges or blisters on the sidewall
- Deep cuts, cracks, or tears
- Any exposed cords or fabric
- Sudden vibration or pulling after an impact
Tyres exhibiting these symptoms are considered unsafe and should be inspected by a professional immediately to prevent a potential blowout.
