Information for measuring tire tread depth:
Move slide (2) before each measurement on the driver (3) up to contact surface, Otherwise measurement errors can occur.
Mount the brake pad check gauge (1) on two tread blocks at the point of maximum tire wear.
Push the feeler gauge (4) into the tread groove until it touches the groove bottom.
The measuring drift (4) must not contact the wear marking. Remove brake pad check gauge (1) for reading off the measured value.
