When it comes to an MOT test, it's essential to know what checks are carried out on your car. The MOT test is a comprehensive inspection that determines if your vehicle meets the legal requirements for roadworthiness and safety. One of the crucial components that the tester examines is your car's tyres.

In this blog, we will explore if tyres are checked during an MOT and what the tester looks for when inspecting them.

Are Tyres Checked in an MOT?

Yes, tyres are thoroughly checked in an MOT test. In fact, they are one of the essential components that the tester examines. The condition of your car's tyres is vital for your safety and that of other road users. Tyres with worn-out treads, bulges, or cuts can cause accidents, and hence it's necessary to ensure that they are in good condition before driving.

What Does the MOT Tester Check on the Tyres?

The MOT tester inspects the tyres to ensure that they are in a roadworthy condition. During the test, the tester checks the following

Tyre Tread Depth

The tread depth of your car's tyres must be above the legal limit of 1.6mm. The tester uses a tread depth gauge to measure the depth of the tread. If the depth is below the legal limit, your car will fail the MOT test. The reason for this is that the tread provides the necessary grip and traction that your car needs to maintain control on the road.

Tyre Condition

The condition of the tyres is also checked during the MOT test. The tester inspects the tyres for cuts, bulges, or any other damage that can affect their safety. If there are any defects, the tester will recommend that you replace the tyres before driving. Driving with damaged tyres can cause blowouts or punctures, which can be dangerous, especially at high speeds.

Tyre Type and Size

The tester also checks if the tyres fitted on your car meet the manufacturer's recommended specifications. The tyres must be of the right size, load rating, and speed rating. If you have fitted tyres that are not recommended for your car, you risk compromising its safety and performance. To find the correct size tyres for your vehicle, click the button below.

Tyre Pressure

Tyre pressure is another critical aspect of tyre safety. Low tyre pressure can cause the tyres to wear out prematurely, reduce fuel efficiency, and compromise the vehicle's handling and stability. During the MOT test, the tester will inspect the tyre pressure and ensure that it meets the manufacturer's recommended specifications.

Tyre Alignment

The tester also checks the alignment of the tyres. If the tyres are not correctly aligned, it can cause uneven wear, affect the vehicle's handling, and compromise safety. The tester will inspect the tyres for signs of uneven wear and recommend alignment correction if necessary.

What Happens If Your Car Fails the Tyre Checks in an MOT?

If your car fails the tyre checks during an MOT test, you will be issued with an MOT failure certificate. This means that you cannot legally drive your car on the road until you have repaired the defects and retested the vehicle.

In the case of tyre defects, you will need to replace the faulty tyres before retesting the vehicle. You can either purchase new tyres or buy used ones that meet the legal requirements. However, it's essential to ensure that the tyres you buy are of good quality and meet the required safety standards.

Tyres are thoroughly checked during an MOT test, and it's vital to ensure that they are in a roadworthy condition. The tester inspects the tread depth, condition, type, size, pressure, and alignment of the tyres. If your car fails the tyre checks, you will need to have your tyres repaired or replaced before you can have an MOT re-test, as the tyres will be checked again to ensure they are safe and legal.

What are the risks of dangerous tyres?

Every year, dangerous tyres lead to around 5,000 convictions, 900 casualties, and 160 deaths or serious injuries. Not only that, but illegal tyres can actually end up costing you more than the price of a new set: you could face fines of up to £2500 and 3 points on your licence per illegal tyre, not to mention that if you're found to have illegal tyres in an accident, it can invalidate your insurance.
