FAQs

For the most optimal driving experience, good ride comfort and traction, experts suggest changing all four tyres at the same time. However, in certain cases, you may be able to get away with just replacing one tyre but when you do, make sure it matches the other three tyres in terms of size and type.

Apart from the legal tread depth limit of 1.6mm, other specific tyre requirements that must be met for the MOT test include the following:

• Tyre condition: Tyres must be in good condition, with no cuts, bulges, or lumps on the sidewall or tread.
• Tyre pressure: Tyres must be inflated to the correct pressure, as specified by the vehicle manufacturer.
• Type and size: Tyres must be the correct size and type for the vehicle, as specified in the vehicle handbook.
• Tyre speed rating: The speed rating of the tyres must be equal to or greater than the maximum speed of the vehicle.
• Tyre load capacity: Tyres must have a load capacity that is equal to or greater than the maximum weight of the vehicle.

In the UK, the legal minimum tyre tread depth for a car to pass its MOT is 1.6mm across the central three-quarters of the tyre’s tread. Any tread depth below this limit is considered unsafe and illegal, resulting in an MOT failure.

While the minimum legal tyre tread depth is 1.6 mm, many experts recommend replacing your tyres when the tread depth reaches 3mm and no less than 2mm. This can help to maintain better grip, stability and braking performance in all weather conditions.
