A pneumatic tire has an aggressive tread pattern for use on both on-road and off-road vehicles having at least a pair of intermediate ribs and a pair of shoulder ribs providing the ground engaging tread lugs. A plurality of circumferentially extending lug groups are formed on and extend outwardly from and along the sidewalls of the tire. Each lug group preferably includes three separate lugs, each lug having a substantially flat outer surface lying in a different plane than the outer surfaces of the other two lugs. Two of the lugs are radially aligned with each other along the sidewall of the tire with the third lug lying intermediate spaced pairs of these aligned lugs. The lugs are formed with sharp corners offset from each other which extend outwardly from the sidewall to different levels. A top surface of one of the lugs aligns with the ground engaging surface of an adjacent shoulder rib tread lug and the top surface of the intermediate lug aligns with the inner tread surface of the road engaging tread pattern.
