10 Tyre Safety Tips Every UK Driver Must Know
Your tyres are the only part of your car that touches the road. These 10 tips from our technicians could save your life — and definitely save you money.
1. Check Pressure Fortnightly
Under-inflated tyres increase braking distance, waste fuel, and wear unevenly. Check when cold — use the pressure on your door frame sticker, not the tyre sidewall. Full pressure guide here.
2. Know the Legal Tread Limit — But Don't Wait That Long
The UK legal minimum is 1.6mm across the central three-quarters of the tread. But tyre performance degrades significantly below 3mm, especially in the wet. We recommend replacing at 2–3mm. Full tread depth guide.
3. Use the 20p Test
Insert a 20p coin into the main tread grooves. If the outer band of the coin is visible, your tread is below 2mm and the tyre should be replaced. Do this in several places across the tyre — wear isn't always even.
4. Inspect Sidewalls Regularly
Bulges, cuts, cracks, or bubbles on the sidewall mean the tyre's structural integrity is compromised. A sidewall bulge can lead to a sudden blowout. If you spot one, replace the tyre immediately — it cannot be repaired.
5. Don't Mix Tyre Types on the Same Axle
UK law requires that tyres on the same axle must be the same size, structure (radial/cross-ply), and speed rating. Mixing different brands is technically legal but not recommended — ideally, match all four tyres for predictable handling.
6. Check Tyre Age
Rubber degrades over time, regardless of tread depth. Tyres older than 5 years should be inspected carefully; tyres over 10 years old should be replaced even if they look fine. The manufacturing date is stamped on the sidewall as a 4-digit DOT code (e.g., 2423 = week 24 of 2023).
7. Carry a Pressure Gauge
Petrol station air machines are notoriously inaccurate. A decent digital tyre pressure gauge costs under Call for a quote and gives you a reliable reading every time. Keep one in the glovebox.
8. Watch for Vibration
Vibration through the steering wheel at speed is the most common sign of a wheel balance issue. It's not just uncomfortable — it accelerates tyre wear and puts stress on suspension components. Get it checked promptly. Mobile balancing service.
9. Avoid Kerbing
Hitting kerbs damages the tyre sidewall and can dent or crack the wheel rim. Even if there's no visible damage, the internal structure can be weakened. Be especially careful when parallel parking — the sidewall is the tyre's weakest point.
10. Don't Ignore the TPMS Light
If your TPMS warning light comes on, stop and check your pressures as soon as it's safe. It means at least one tyre is significantly under-inflated. Driving on a seriously under-inflated tyre can cause it to overheat and fail catastrophically.
