The minimum legal tread depth for tires in the Philippines is 1.6 mm. This standard is critical for ensuring adequate traction and handling performance. Tires with sufficient tread depth can better grip the road surface, especially in wet or slippery conditions, which reduces the risk of accidents.

Tread depth is an essential factor in maintaining vehicle safety. When tread depth falls below the specified minimum, the tires lose their effectiveness in channeling water away, leading to an increased likelihood of hydroplaning. Therefore, maintaining at least 1.6 mm of tread depth is vital for drivers to ensure their vehicles can perform adequately in various driving conditions.

In contrast, the other tread depth options presented are above the minimum legal requirement and, while measuring deeper treads can contribute to improved grip and safety, they do not represent the mandatory legal standard. Understanding this legal requirement is crucial for any driver to ensure compliance and enhance road safety.
