MOT & Spare Wheels: What You Need to Know

It's a question that often sparks debate amongst motorists: why isn't a spare tyre a mandatory item for your vehicle's MOT test? Many drivers assume that anything essential for road safety would be checked during the annual inspection. However, the reality is a little more nuanced, and understanding the reasoning behind this exclusion can save you confusion and potential fines. This article delves into the specifics of MOT testing, the role of spare wheels, and what you genuinely need to have in your vehicle to pass.

The Purpose of the MOT Test

The MOT (Ministry of Transport) test is a crucial annual inspection designed to ensure your vehicle is safe and roadworthy. It focuses on critical safety components that, if faulty, could pose a danger to the driver, passengers, or other road users. These areas include:

• Brakes: Ensuring they are effective and meet legal requirements.
• Lights: Checking all lights are working correctly and are the appropriate colour.
• Steering and Suspension: Examining for excessive wear or damage.
• Tyres: Assessing tread depth (minimum 1.6mm), condition (no cuts or bulges), and correct inflation.
• Exhaust System: Checking for leaks, noise levels, and emissions.
• Body and Chassis: Looking for significant corrosion or structural damage.
• Seatbelts: Ensuring they are present, correctly fitted, and functional.
• Windscreen: Checking for clear visibility and no damage in the driver's field of vision.

The MOT is fundamentally about the current condition of these vital systems. It's a snapshot of your vehicle's roadworthiness on a specific day.

Why Spare Tyres Aren't Tested

The primary reason a spare tyre isn't included in the MOT test is that it's considered a secondary safety item and, crucially, not an essential component for the vehicle to operate safely on the road at the time of the test. The MOT examiners are assessing the tyres currently fitted to the vehicle. As long as those tyres meet the legal requirements for tread depth, condition, and size, the vehicle will pass that particular aspect of the test, regardless of whether a spare is present.

Think of it this way: the MOT isn't a test of your vehicle's emergency preparedness. It's a test of its immediate operational safety. A flat or missing spare tyre doesn't inherently make the car unsafe to drive during the test itself, provided the main tyres are legal.

What About Space-Saver Spares?

Even the more compact 'space-saver' or 'temporary' spare wheels are not mandated for the MOT. While these are designed for short-term use until a full-sized tyre can be fitted, they still fall outside the scope of the standard MOT inspection. The condition, pressure, and legality of the tyres currently mounted on the vehicle's wheels are what the tester will examine.

The Legal Requirement for Spare Tyres

While the MOT doesn't require you to have a spare tyre, there are still legal obligations regarding carrying one. The Road Traffic Act 1988, and subsequent regulations, do stipulate that a vehicle must be equipped with tyres that are in a legal condition. This implies that if you have a spare tyre fitted, it must also meet the legal requirements concerning tread depth, damage, and inflation. However, this is more about general road use than a specific MOT mandate.

More importantly, if your vehicle is equipped with a spare tyre as standard from the manufacturer, then that tyre, when it is fitted to the wheel, must meet the legal requirements. If you choose not to carry a spare, or if your vehicle doesn't come with one, you are not breaking the law by not having one.

Tyre Repair Kits vs. Spare Tyres

Many modern vehicles, particularly electric vehicles and those designed with space efficiency in mind, are now supplied with tyre repair kits instead of spare wheels. These kits typically include a sealant and an inflator. These are also not part of the MOT test. The MOT focuses on the tyres fitted to the vehicle, not the emergency equipment you carry.

What the MOT *Does* Check Regarding Tyres

It's crucial to understand what the MOT does check concerning tyres. These are the elements that can lead to an MOT failure:

Why is it Still Important to Carry a Spare Tyre (or Repair Kit)?

Even though it's not an MOT requirement, carrying a spare tyre, a space-saver, or a tyre repair kit is highly recommended for practical reasons. A puncture can happen at any time, often in inconvenient locations, and being stranded without a way to remedy the situation can be stressful and potentially dangerous.

Preparedness is key for any driver. Having a spare tyre or a repair kit allows you to deal with a flat tyre promptly, minimising disruption to your journey and ensuring you aren't left vulnerable on the roadside.

Common Misconceptions

There are several common misconceptions about spare tyres and the MOT:

• Misconception: If you have a spare tyre, it *must* be checked during the MOT.
• Reality: The MOT only checks the tyres currently fitted to the vehicle. The spare is irrelevant to the test.
• Misconception: You are legally required to carry a spare tyre at all times.
• Reality: While it's wise to carry one, it's not a legal requirement for all vehicles. However, if your vehicle is equipped with one, it must be roadworthy.
• Misconception: A space-saver spare tyre is not legal for use.
• Reality: Space-savers are legal for temporary use, but you must adhere to their speed and distance limitations. They are not tested in the MOT.

What If Your Spare Tyre is Fitted for the MOT?

If, for whatever reason, you choose to fit your spare tyre to the vehicle *for* the MOT test (perhaps your regular tyre is below the legal limit, and the spare is currently legal), then the spare tyre will be assessed like any other tyre. It must meet all the legal requirements for tread depth, condition, and size. However, this is a strategic choice by the owner, not a requirement of the test itself.

Conclusion

In summary, the MOT test is a rigorous examination of your vehicle's current roadworthiness, focusing on essential safety components. While a spare tyre is a valuable item for dealing with unexpected punctures, it is not considered a mandatory component for passing the MOT. The test ensures the tyres on the car are legal and safe. However, for your own peace of mind and preparedness on the road, it is always advisable to carry a functional spare tyre or a reliable tyre repair kit. Stay safe and drive responsibly!

Frequently Asked Questions

Q1: Does my MOT certificate mention anything about a spare tyre?

A1: No, the MOT certificate will not mention the presence or absence of a spare tyre. It only records the results of the tested safety items.

Q2: What happens if I have a space-saver spare and it's fitted during the MOT?

A2: If a space-saver spare is fitted to the vehicle during the MOT, it will be tested. It must meet the legal requirements for tread depth (which is often less critical for space-savers but still needs to be safe) and condition. However, the speed and distance limitations of space-savers are not part of the MOT check.

Q3: Are tyre repair kits checked in the MOT?

A3: No, tyre repair kits are not checked during the MOT. Like spare wheels, they are considered emergency equipment rather than essential operational components for the test.

Q4: What is the minimum tread depth required for an MOT?

A4: The legal minimum tread depth for all tyres fitted to a vehicle for its MOT is 1.6mm across the central three-quarters of the breadth of the tread and around its entire circumference.

Q5: Should I check my spare tyre's pressure?

A5: Yes, it's a good practice to check the pressure of your spare tyre periodically, just as you would your regular tyres. A flat spare tyre is of little use. Many manufacturers recommend checking it every few months.

Q6: What if my car doesn't come with a spare tyre? Do I need to buy one for the MOT?

A6: No, you do not need to buy a spare tyre if your vehicle was not originally equipped with one. The MOT test does not require you to carry one.

Q7: Can a damaged spare tyre cause an MOT failure?

A7: The spare tyre itself is not tested. However, if you were to fit a damaged spare tyre to your vehicle *during* the MOT test in place of a faulty regular tyre, then that fitted spare tyre would be inspected and could cause a failure if it doesn't meet the legal requirements.

Q8: What is the most important tyre aspect checked in an MOT?

A8: The most critical tyre aspects checked are tread depth and the overall condition of the tyre (absence of cuts, bulges, etc.). Tyres must be the correct size and type for the vehicle.
