Heavy Duty Pneumatic Redial Tire having Abrasion Mark of Limitation

摘要

The present invention relates to a wear limit indicator that displays the wear limit time of the tire on the side surface of the shoulder portion of the tire, and constitutes a wear limit indicator as a horizontal line that protrudes at regular intervals so as to change the tire replacement time. It relates to a pneumatic radial tire having a wear limit display protrusion for easily identifying and preventing a safety accident due to excessive wear of the tire. The inside of the groove formed on the tread surface of the pneumatic radial tire In the rubber projections (3) indicating the wear limit point position of the tire in the tire, the upper end position of the rubber projection (3) in the shoulder portion side wall (S) of the tire is a plurality of projection lines (m1, m2, .. It is a pneumatic radial tire formed with a projection (M) for abrasion limit position indication indicated by ... mn).
