How Old Are Your Tyres? Why Tyre Age Matters Even With Good Tread

A tyre can have plenty of tread left but still be dangerous due to age. Learn how to check your tyre age and why tyres over 6 years old should be inspected carefully.

Most drivers replace their tyres when the tread wears down, but tyre age is equally important — and often completely overlooked. Rubber degrades over time regardless of use.

How to Check Your Tyre Age

Every tyre has a DOT code stamped on the sidewall. The last four digits tell you the manufacturing date: - 2218 = 22nd week of 2018 - 0421 = 4th week of 2021

When Should You Replace Old Tyres?

Most tyre manufacturers recommend replacing tyres after 6 years regardless of remaining tread depth. After 10 years, tyres should be replaced immediately regardless of appearance.

Why Rubber Degrades

Rubber oxidises when exposed to air, UV light, heat, and ozone. This process (called tyre degradation or perishing) causes: - Micro-cracking in the sidewall - Loss of flexibility in the tread compound - Increased risk of sudden blowout - Reduced wet-weather grip

Signs of an Aged Tyre

• Visible cracks in the sidewall (even small ones are a warning sign)
• Hardened, dry-feeling rubber
• Crazing or spider web-like surface cracking
• Discolouration or fading

Classic and Low-Mileage Vehicles

Tyres on classic cars or lightly used vehicles are particularly at risk. A 7-year-old tyre with full tread is still a 7-year-old tyre. Eddie's Mobile Tyres can inspect and advise on your tyre age at your door.
