15 Warning Signs You Need New Tyres 

When was the last time you checked your tyres? They’re the only part of your car that actually touches the road—yet they’re often forgotten until something goes wrong. In the UK’s unpredictable weather, worn, punctured or damaged tyres can quickly become a serious safety hazard.

To help you stay safe and avoid costly MOT failures or dangerous blowouts, here are the 15 most important signs you need new tyres—plus tips on how to check them yourself.

🚨 1. Tread Depth Below the 1.6 mm UK Legal Minimum

The law requires at least 1.6 mm of tread depth across the central three-quarters of the tyre.
Quick test: Insert a 20p coin into the tread. If you can see the coin’s outer rim, it’s time for new tyres.
Why it matters: Worn tread greatly reduces grip and increases stopping distance, especially in wet weather.

⚠️ 2. Cracks, Bulges or Blisters in the Sidewall

Cracks, splits or bulges are a red flag that the tyre’s internal structure is compromised.
This damage can lead to a sudden blowout—particularly at motorway speeds.

📉 3. Uneven Tyre Wear

If one side of the tyre is more worn than the other, your wheel alignment, suspension or tyre pressure may be off. Uneven wear shortens tyre life and reduces performance.

🔧 4. Excessive Vibration While Driving

Steering wheel shakes or unusual vibration may indicate imbalanced wheels, internal tyre damage or misalignment. Have it checked immediately.

💨 5. Frequent Loss of Pressure

If you’re topping up your tyres every week, there could be a slow puncture, valve issue or rim leak. Driving on under-inflated tyres wastes fuel and weakens the structure.

💀 6. Visible Wires or Fabric

Spotting steel cords or fabric threads means the tyre is dangerously worn and illegal to drive on. Replace it immediately.

📅 7. Tyres Over Six Years Old

Even if tread looks fine, rubber degrades with age. Most tyre manufacturers recommend replacing tyres every six years, and never beyond ten, no matter the mileage.

🌧️ 8. Poor Grip in Wet Weather

If your car aquaplanes easily or skids, your tyres may no longer disperse water effectively, putting you at risk of losing control.

🔊 9. Strange Noises on the Road

Unusual humming, thudding or squealing often points to internal separation or uneven wear. Get a professional inspection.

🕳️ 10. Damage After Hitting a Pothole or Kerb

A single impact can cause hidden sidewall or bead damage. Always check for cuts, bulges or slow leaks after hitting a pothole or kerb.

⚠️ 11. TPMS Warning Light Keeps Coming On

Most modern cars have a Tyre Pressure Monitoring System (TPMS).
If the light flashes repeatedly, don’t ignore it—there’s likely a leak or structural problem.

🛑 12. Longer Stopping Distances

If your car needs more distance to brake—despite healthy brakes—your tyre grip may be compromised.

❄️ 13. Using the Wrong Tyres for the Season

Summer tyres in winter (or vice versa) lose grip in cold, wet or icy conditions.
Switch to seasonal or all-season tyres for optimal safety.

❌ 14. MOT Failure Due to Tyres

If your car fails its MOT because of tyre wear or damage, you must replace the affected tyres before retesting. Driving without doing so is illegal.

🧳 15. Planning a Long Journey or Holiday

Before any long road trip, inspect your tyres carefully. Fresh tyres mean peace of mind and safer travels.

How to Check Tyres at Home (Quick & Easy)

• Tread: Use a 20p coin or a dedicated tread depth gauge.

• Pressure: Check at least once a month and before long trips.

• Visual inspection: Look for cuts, bulges, nails, or embedded debris.

• Listen and feel: Pay attention to vibration or unusual noises.
