Your tyres are the only part of your car that actually touches the road, making them one of the most important components for safety and performance. Whether you commute daily through Aldershot, take longer motorway trips, or drive less frequently, knowing when to replace your tyres is essential. Worn or damaged tyres can increase stopping distances, reduce grip in wet or icy conditions, and even lead to dangerous blowouts.
Replacing tyres at the right time is not only a matter of safety but also a legal requirement in the UK. Understanding how to monitor tread depth, tyre age, and overall condition helps ensure your vehicle remains reliable and road-legal. This guide will walk you through the key signs that indicate when it’s time to replace your tyres, common questions drivers ask, and how professional services like GForce Tyres can help you stay safe on the road.
Why Tyre Replacement Matters?
Tyres are vital for braking, steering, handling, and overall vehicle stability. Over time, they wear down due to mileage, road conditions, and driving habits. As tread reduces, braking distances increase, grip diminishes, and the risk of aquaplaning in wet conditions rises. Driving on worn tyres also increases the likelihood of punctures and blowouts. Ignoring tyre maintenance can lead to safety hazards, fines, or an MOT failure.
UK Legal Requirements for Tyre Tread
In the UK, the law requires a minimum tread depth of 1.6 mm across the central three-quarters of the tyre’s width and around its entire circumference. Tyres below this limit are illegal and must be replaced.
However, for optimal safety, many experts recommend replacing tyres before they reach this minimum, usually around 3 mm of tread depth, to maintain good wet-weather performance and reduce the risk of aquaplaning.
1. Tread Depth: The Most Important Indicator
How Tread Works
Tyre tread channels water away from the contact patch, improving grip and reducing the risk of skidding. Healthy tread also ensures better braking performance and overall vehicle control. Regular inspections during a car service help identify early tyre wear.
How to Measure Tread Depth
You can check tread depth with:
- A tread depth gauge for accuracy.
- A 20p coin test: Insert a 20p coin into the main grooves of the tyre. If the outer rim of the coin is visible, the tread is shallow and may need replacement.
When to Replace
- Above 3 mm: Safe performance and good grip.
- Around 3 mm: Plan replacement soon, especially before winter.
- 1.6 mm: Legal minimum, tyres must be replaced.
Remember, tread may wear unevenly, so check all tyres regularly or have them inspected during a wheel alignment check.
2. Pay Attention to Age and Rubber Degradation
Tyres also deteriorate with age, even if tread depth is adequate. Rubber hardens and cracks over time due to oxidation, UV exposure, and temperature changes.
- Have tyres inspected professionally after five years of use.
- Consider replacement by seven years, even if tread is sufficient.
- Do not use tyres beyond ten years, regardless of tread.
You can find the tyre’s age on the sidewall using the DOT code, a four-digit number indicating the week and year of production.
3. Visible Damage and Structural Concerns
Even if tread and age are fine, visible damage can make tyres unsafe:
- Sidewall bulges or blisters
- Deep cuts or cracks in the rubber
- Punctures that cannot be repaired
- Objects lodged in the tread
- Uneven wear patterns
Any of these issues can weaken the tyre’s structure and increase the risk of blowouts. A professional tyre inspection is recommended immediately.
4. Symptoms While Driving
Warning signs can appear while driving:
- Vibration or shaking through the steering wheel
- Pulling to one side
- Longer stopping distances
- Reduced grip in wet conditions
If you notice any of these signs, have your tyres inspected promptly along with a brake check to ensure full safety.
5. Tyres and Seasonal Driving
Tyres perform differently in varying weather conditions:
- Wet autumn and winter conditions demand good tread for grip and aquaplaning resistance.
- Summer heat can accelerate wear or cause pressure fluctuations.
Replacing tyres before high-demand seasons improves safety and allows you time to choose the right tyres without urgency.

FAQ’s
How Often Should I Check My Tyres?
Check tyres at least once a month and before long journeys. Regular inspection helps monitor tread, pressure, and damage.
Should I Replace All Four Tyres at Once?
If all tyres are worn, replacing all four is ideal. If only two are worn, replacing them in pairs (front or rear) helps maintain balanced handling, particularly for front-wheel-drive vehicles.
Can I Keep Driving After One Tyre Reaches the Legal Limit?
No. Driving below the legal 1.6 mm tread depth is unsafe and illegal. Safety experts recommend replacing tyres around 3 mm of tread for better wet-weather performance.
