What are the key signs I need new tyres?

Signs you need new tyres

Knowing what to look for helps you catch tyre problems early and stay safe on the road.

Visual signs

• Low tread depth - At or approaching 3mm. Use the 20p test to check.
• Cracks on the sidewall - Small surface cracks can progress and indicate ageing rubber
• Bulges or blisters - Weak spots in the sidewall that indicate internal structural damage
• Uneven wear - Wear concentrated on one edge or the centre suggests alignment or pressure problems
• Embedded objects - Nails, screws or glass in the tread

Driving signs

• Vibration through the steering wheel at speed
• The car pulling to one side under braking or at a constant speed
• Reduced grip in wet conditions that was not noticeable before
• Increased road noise

Age

Tyres older than 5 to 6 years should be inspected carefully and replaced if there are any signs of degradation, regardless of remaining tread depth.
