Fleet FAQ
Q:
What is the legal tyre tread depth limit?
A:
The legal limit for minimum depth of the tread on your tyres is 1.6 millimetres, across the central ¾ of the tread around the complete circumference of the tyre.
Kwik Fit says the majority of companies have policies that tyres will be replaced at 2mm for safety and compliance reasons.
