MOTORING NEWS - Tyre tread is important because it helps remove water between the tyre and road, ensuring the car remains under control and preventing the risk of aquaplaning.
Tyres wear out over time. This can be accelerated by uneven road surfaces, the tyre design itself and driving practices such as high-speed driving and hard braking.
The minimum tread depth required is 1mm. The tread depth influences the face of the tyre that is in contact with the road.
It's easy to check if the tyre meets this by checking the tread wear indicator on a tyre. These bars are placed at regular points across the tread and they will be level with the tread blocks when the minimum tread is reached.
