Your car’s tyres are one of the most important parts of your MOT test. If they are not in good shape, your car can fail its MOT. Many drivers in Fleet don’t realise how strict the tyre rules are — until it’s too late.
At TJ Services, we help drivers pass their MOT with confidence by checking tyres ahead of time. Let’s go through the tyre rules, what testers look for, and how to stay safe (and legal) on the road.
1. Tread Depth Must Be Legal
By law, your tyres must have at least 1.6mm of tread across the middle 3/4 of the tyre. This is checked with a tool called a tread gauge.
If your tyres are below this limit, your car will fail — no exceptions. For safe driving and to avoid an MOT retest in Fleet, we always recommend changing tyres when they reach 2mm.
2. Tyres Must Be the Right Type and Size
All tyres on your car must be the correct size and type for your vehicle. Mixing different types (like a winter tyre with three summer tyres) can cause a fail.
At TJ Services in Fleet, we can check your tyres and let you know if they’re mismatched or unsuitable — and help you fix it fast.
3. No Cuts, Bulges or Damage
Even if your tread is legal, your tyre can still fail if it has:
- Cuts or deep cracks
- Bulges in the sidewall
- Nails or sharp objects stuck inside
- Exposed cords
These signs mean the tyre could blow out, which is dangerous.
If you’re unsure whether your tyres meet the MOT rules in Fleet, pop by our garage for a free visual check.
4. Tyre Pressure Warning Light (TPMS)
If your car has a Tyre Pressure Monitoring System (TPMS), the warning light must not be on during the MOT. If it is, your car can fail — even if the tyres look okay.
We can reset TPMS systems or repair sensors at our MOT garage in Fleet, so you don’t get caught out by a simple dashboard light.
5. Spare Tyres Aren’t Tested
Your MOT tester won’t check the spare tyre — unless it’s fitted to the car at the time of the test. But it’s still smart to make sure your spare is safe in case of a roadside emergency.
We offer full tyre checks with every MOT in Fleet so you have peace of mind before test day.
6. Tyres Must Be Fitted Properly
Your tyres need to be fitted in the correct direction (for directional tyres) and seated correctly on the rims. A tyre mounted the wrong way round can cause failure, especially in wet conditions.
If you’ve changed tyres yourself or used a quick-fit service, it’s a good idea to get a second look at TJ Services before your test.
Why It Matters
Your tyres are your car’s only contact with the road. Worn or damaged tyres don’t just risk a failed MOT — they can lead to:
- Long stopping distances
- Poor grip in rain
- Increased chance of blowouts
- Fines and points on your license
When it’s time for your MOT in Fleet, don’t take a chance. Let us check your tyres and help you avoid unnecessary trouble.

FAQs
Q: Can I pass MOT with a tyre just above 1.6mm?
Yes, but we recommend replacing it soon. Below 1.6mm is illegal.
Q: Do tyres on all four wheels need to match?
Yes — they must be suitable for the car and not mismatched types.
Q: Does the MOT check tyre pressure?
Not directly. But if your TPMS light is on, you can fail.
