ABSTRACT:
A heavy duty pneumatic tire is disclosed, which comprises a plurality of main grooves extending in a tire circumferential direction, shoulder land portions formed between the main grooves on the shoulder portions and edges of a tread, and a plurality of lateral grooves extending axially inwardly and outwardly in a tire axial direction on the shoulder land portions from the tread edges and spaced at an interval in the tire circumferential direction. The lateral grooves include the tread edges, and consist of two kinds of lateral grooves having different axial distances W.sub.1 and W.sub.2 from the tread edge to axially inward ends of the bottoms of the lateral grooves. An amplitude of the shoulder main grooves is varied corresponding to positions of the respective lateral grooves such that distances L.sub.1 and L.sub.2 from the radially inner ends of the lateral grooves to the axially outermost walls of the shoulder main grooves on the sides of the shoulder land portions adjoining the respective lateral grooves may be substantially equal to each other or in a range from (L.sub.1 -L.sub.2)/TW.ltoreq.0.06.
