ことを特徴とする重トラツク用タイヤ。[Claims for Utility Model Registration] A ground-contacting tread portion having a pair of shoulder portions located at each lateral edge and defining a central tread portion;
Mainly used on roads having a pair of sidewall portions each extending radially inward from each shoulder portion of the tread portion and terminating in a pair of bead portions, and a carcass layer structure extending from the bead portion to the bead portion. In a heavy truck tire, the ground contact tread portion consists of a pair of ribs located at the shoulders and extending continuously in the circumferential direction, and a central tread portion consisting of a number of independent protrusions formed substantially in the same way. , the independent protrusions are shaped and of the tread portion to define a plurality of substantially parallel circumferentially extending independent protrusion rows separated by a plurality of substantially circumferentially extending zigzag grooves. The independent protrusions in each row are arranged around circumferentially adjacent independent protrusions separated by a substantially straight narrow groove having a width of about 1 mm or less on the opposing sides of each adjacent independent protrusion. When the adjacent independent protrusions are in the tire tread position, said narrow groove closes, so that each adjacent independent protrusion acts as a unit to resist lateral and circumferential forces. was made,
The depth of the narrow groove between the adjacent independent protrusions is at least 30% of the depth of the zigzag groove, and the ratio of the average circumferential width to the average axle length of each independent protrusion is 0.6. 1.0 and wherein said narrow groove is at an angle of about 70 degrees to 85 degrees with respect to the intermediate circumferential center plane of said tire.
