Abstract

A heavy load pneumatic radial tire which has excellent wear resistance against heavy loads is herein disclosed. The radial tire has a tread portion which comprises long and short blocks for forming grooves which allow platforms to be disposed therein. Each of the platforms has predetermined height and length so that the total area of the grooves is decreased as the tread portion of the tire is worn.
