🛞 Tyres and MOT: What We Check and Why They Fail

By Andrews Car Centre – Trusted MOT & Tyre Experts in Lincoln

When it comes to your MOT, tyres are one of the most common reasons for a fail. But what exactly do testers look for — and how can you avoid unexpected costs or delays?

At Andrews Car Centre in Lincoln, we carry out hundreds of MOTs every month. Here’s exactly what’s checked on your tyres during an MOT, why they fail, and what you can do to stay safe (and legal).

🔍 What Do We Check on Tyres During an MOT?

During your MOT test, we thoroughly inspect each tyre for:

✅ Tread Depth

• The legal minimum tread depth is 1.6mm across the central three-quarters of the tyre.

• Anything below this fails immediately — and can even earn you points on your licence and a fine if caught on the road.

✅ Condition and Damage

We look for:

• Cuts or cracks

• Bulges or lumps

• Exposed cords or fabric

• Objects embedded in the tread

Any of these can compromise safety and lead to a fail.

✅ Tyre Type and Suitability

All four tyres (and the spare, if fitted) must:

• Be the correct type for your car

• Match across the same axle (e.g., no mixing different tread patterns)

✅ Tyre Pressure (Indirectly)

While not directly tested, tyres must be visibly inflated correctly. Severely underinflated or flat tyres can cause a fail if they affect the overall condition or safety.

❌ Common Reasons Tyres Fail an MOT

1. Worn tread below 1.6mm — the most frequent reason.

2. Sidewall damage or bulges from hitting kerbs or potholes.

3. Cuts or cords showing, often from driving on underinflated tyres.

4. Incorrect or mismatched tyres on the same axle.

5. Age-related cracking, especially on low-mileage or rarely used cars.

💡 How to Avoid a Tyre-Related MOT Fail

✔️ Check your tread depth regularly with a gauge — or use the “20p test.”
✔️ Look at sidewalls for cracks or bulges.
✔️ Maintain correct tyre pressures (check monthly).
✔️ Rotate tyres if needed to even out wear.
