HGV Tyre Maintenence
Current tread depth legislation requires that truck tyres must have a minimum of 1mm of tread in a continuous band throughout the central three-quarters of the tread width and over the whole circumference of the tyre. The same regulation applies to regrooved tyres. The driver of the vehicle is responsible for making sure his/her tyres are legal and in a roadworthy condition. The penalty for driving with an illegal tyre is 2,500 and three penalty points per tyre.
When driving in wet weather, the tread pattern of the tyre helps to evacuate surface water from the road. As the tread begins to wear down, the tyre gradually loses the ability to evacuate all the water from the road surface, which increases stopping distances in the wet. The lower the tread depth, the greater the risk of aquaplaning.
