Will Your Car Pass an MOT Without a Spare Tyre? The Truth

When preparing for your MOT test, you might wonder whether having a spare tyre in your vehicle is a requirement. After all, tyres play a crucial role in road safety, and a faulty or missing spare might seem like a problem. But will your car actually fail an MOT without one? Let’s break down the facts according to UK MOT rules.

Is a Spare Tyre Required for an MOT?

In the UK, having a spare tyre is not a legal requirement for passing an MOT. The test only examines the tyres currently fitted to the car and in use on the road. This means that if your vehicle doesn’t have a spare, or if you’ve removed it entirely, you won’t automatically fail the MOT because of it.

When a Spare Tyre Is Checked During MOT

While a spare tyre is not part of the standard MOT checklist, there is one exception — if a spare tyre is fitted to the vehicle at the time of the test, it will be inspected.

This means:

• If the spare tyre is mounted and in use (replacing one of your main tyres), it must meet the legal tread depth and condition requirements.
• If the spare is stored in the boot and not in use, it won’t be checked.

What the MOT Actually Checks for Tyres

During an MOT, the examiner will check:

• Tread depth – Must be at least 1.6mm across the central three-quarters of the tyre.
• Condition – No cuts, bulges, or damage.
• Correct type – All tyres must be suitable for the vehicle and road conditions.
• Inflation – Tyres must be inflated to a safe level.

The focus is entirely on the tyres in active use, not any spares stored away.

What About Space-Saver or Temporary Spares?

Some modern cars come with a space-saver spare or even a puncture repair kit instead of a full-sized spare. These are not part of the MOT assessment unless they are actually fitted on the car at the time of the test.

However, if you have to use a space-saver tyre temporarily, remember they are not designed for long-term driving and may have speed and distance limits clearly marked on the tyre.

Safety Considerations Even If It’s Not an MOT Requirement

While a spare tyre isn’t necessary to pass an MOT, it’s still a good idea to carry one or an alternative repair kit. A flat tyre on a long journey can leave you stranded, especially in rural areas or at night. Even if your MOT doesn’t require it, being prepared can save you from inconvenience and costly roadside assistance.

Final Thoughts

In summary, your car can pass an MOT without a spare tyre, as UK regulations only focus on the tyres currently in use. However, for peace of mind and safety, having a spare or an alternative emergency solution is always wise. Your MOT might not demand it, but your future self might thank you for it.
