When Should You Replace Your Tyres?
Tyres are the only contact point between your vehicle and the road, making them one of the most critical safety components on your car. Most manufacturers recommend replacing tyres every 6 years, regardless of tread depth, because rubber degrades over time due to UV exposure and temperature changes.
The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre and around the entire circumference. However, safety experts advise replacing tyres when tread depth reaches 3mm, as wet-weather braking performance drops significantly below this level.
Mileage-Based Guidelines
Average drivers in the UK cover approximately 8,000 miles per year. Front tyres typically last between 20,000 and 30,000 miles, while rear tyres can last 40,000 to 50,000 miles. High-performance vehicles and aggressive driving styles will reduce these figures considerably.
Age-Related Degradation
Even with plenty of tread remaining, tyres older than 5-6 years may develop sidewall cracks, bulging, or hardening rubber. Check the DOT code on your sidewall — the last four digits indicate the week and year of manufacture.
If you are unsure about your tyre condition, a mobile tyre fitting service can inspect them at your home or workplace and advise on replacement without you needing to visit a garage.
