What is the minimum allowable tread depth for vehicle tyres?

The minimum allowable tread depth for vehicle tyres is crucial for ensuring safe driving conditions. A tread depth of 1mm is considered the legal minimum, but it is important to understand the implications of driving with such minimal tread. Tread depth affects the vehicle's grip on the road, especially under wet conditions, as insufficient tread depth can lead to reduced traction and increased stopping distances.

While 1mm may be the legal requirement, many safety organizations and experts recommend replacing tyres when the tread depth reaches 3mm or more, as this helps maintain better control of the vehicle in adverse weather conditions. Therefore, knowing that 1mm is the legal minimum emphasizes the importance of regularly checking tyre tread to ensure optimal safety on the road and to prevent accidents caused by hydroplaning or loss of control under braking.
