Tyre Safety and MOT – How Your Tyres Can Cause an MOT Failure
Tyre Safety and MOT – How Your Tyres Can Cause an MOT Failure
When it comes to passing your MOT, tyres are one of the most common culprits for failure. Many drivers overlook their tyres, assuming that if they’re not flat, they’re fine – but tyre condition plays a significant role in road safety and vehicle performance. At Andrews Car Centre in Lincoln, we frequently see vehicles fail their MOT due to tyre-related issues that could have been avoided with regular checks and maintenance.
In this article, we’ll explore how tyres impact your MOT, the most common tyre-related failures, and how to ensure your vehicle passes with flying colours.
Why Tyres Are Critical for Your MOT
Tyres are your car’s point of contact with the road. They affect handling, braking, fuel efficiency, and overall safety. During an MOT test, examiners assess tyres to ensure they meet legal safety standards. Any issues, no matter how small, can result in an advisory notice or outright failure.
In the UK, 1 in 10 MOT failures are due to tyre defects. Many of these could have been avoided by identifying and addressing tyre problems in advance.
What MOT Testers Look for in Tyres
During an MOT, tyre checks focus on several key areas:
- Tread Depth – The legal minimum tread depth is 1.6mm across the central three-quarters of the tyre. Anything less is an automatic fail. Testers will measure tread depth using a gauge or a visual assessment.
- Tyre Condition – Tyres are inspected for cuts, bulges, and cracks. Any damage that exposes the tyre’s internal structure or poses a risk of blowout will result in failure.
- Tyre Pressure – Incorrect tyre pressure may trigger an advisory. Tyres significantly underinflated or overinflated can lead to uneven wear and handling issues.
- Tyre Size and Type – All tyres must be the correct size for the vehicle and match across the same axle. Mismatched or incompatible tyres can affect balance and stability.
- Valve Condition – The valve is checked for leaks or damage that could cause a slow puncture.
- Spare Tyre (if applicable) – Although not part of the mandatory check, if a spare tyre is present, it must also be roadworthy.
Common Tyre-Related MOT Failures
If your vehicle fails its MOT because of tyres, it is often due to:
- Bald Tyres – Tread worn below 1.6mm. This is the most common tyre-related failure.
- Cracked or Perished Tyres – Age-related degradation that causes small cracks on the sidewall.
- Tyre Bulges – Sidewall bulges from pothole damage or weak points in the tyre structure.
- Uneven Tyre Wear – Misaligned wheels or poor suspension can cause tyres to wear unevenly, leading to reduced grip.
- Punctures or Embedded Objects – Nails, screws, or glass in the tyre can cause slow punctures or immediate failure.
How to Avoid Tyre-Related MOT Failures
1. Check Tyre Tread Regularly
- Use the 20p coin test – insert the coin into the tyre’s tread. If the outer band is visible, your tread is too low and may result in an MOT fail.
2. Inspect for Visible Damage
- Look for cracks, cuts, bulges, or objects lodged in the tyre. Even small imperfections can lead to tyre degradation.
3. Maintain Correct Tyre Pressure
- Check your tyre pressure monthly and adjust according to your vehicle’s handbook. Under or over-inflated tyres wear unevenly, reducing lifespan and performance.
4. Align and Balance Your Wheels
- Misaligned wheels cause uneven tread wear, compromising the tyre’s effectiveness. Regular wheel alignment can prolong tyre life and ensure even wear.
