1 - indicators; 2 - indicator position mark
Six or eight wear indicators 1 are mounted in the tire at an equal distance from each other, by which the limiting wear of the tread is determined. A tire with a worn wear indicator must not be used (tread depth 1.6mm).
The position of the indicators is marked on the sidewalls of the tires with marks 2 (triangle or letters TWI).
It is recommended to change tires without waiting for the indicator to appear.
