# Tyre Replacement
Tyres must be replaced when the tread depth is less than **1.6 mm**, which is the minimum legal limit established by traffic regulations. Below this measurement, tyres lose grip and water drainage capacity, significantly increasing the risk of accidents, especially in rainy conditions. It is advisable to change them before reaching this minimum limit to ensure road safety.
