What is the minimum tread depth required for tyres to ensure safe driving?

The minimum tread depth required for tyres to ensure safe driving is 1.6 mm. This depth is essential for maintaining adequate grip and performance on the road, especially in wet conditions. A tread depth of 1.6 mm allows for sufficient water displacement, reducing the risk of aquaplaning and ensuring better traction. When the tread wears down below this minimum, the tyre's ability to grip the road diminishes significantly, which compromises vehicle safety.

Staying above this threshold helps ensure that the vehicle can effectively channel water away from the surface of the tyre, promoting better handling and braking performance. Additionally, regular checks of tyre tread depth are vital for compliance with safety regulations and for overall road safety.
