What is the minimum tread depth required on tyres?

The minimum tread depth required on tyres is crucial for maintaining traction and ensuring the safety of the vehicle, especially in wet conditions. A tread depth of 1 millimeter is regarded as the legal limit in many regions, including the Cayman Islands. This depth is essential because it allows the tyre to effectively channel water away from the contact patch with the road, reducing the risk of hydroplaning and improving grip.

When the tread wears down to this minimum level, the tyres may no longer provide optimal performance, thus affecting the vehicle's handling, braking, and overall driving safety. Maintaining tyres above this minimum depth is important not only for compliance with the law but also for enhancing road safety for the driver and others on the road.
