Embodiment
[0039] As an example, a pneumatic tire of the present invention was tested and mounted on a truck (axle structure 2-D) with a load of 10 tons for evaluation. In addition, the tread patterns of Examples 1 to 3 are the patterns shown in FIGS. 1 , 3 , and 5 , respectively. The depth D of the main groove 1 is 14.5 mm, the height H of the protrusion 3 is 3 mm, W, W1, and W2 in Figures 8 to 10 are 7 mm, 4.5 mm, and 6.5 mm, respectively, and L1, L2 are 23 mm, 17 mm, respectively. The width of shaped pattern 2 is 38mm. The length of the sipe 4 in embodiment 2 is 2.5 mm, the length of the notch 5 in embodiment 3 is 4 mm, and the width of the opening on the side wall 13 is 5.5 mm.
[0040] The tires of Conventional Examples 1 to 3 do not have protrusions having the same patterns as those of Examples 1 to 3. However, Conventional Example 2 has the same sipe as Example 2, and Conventional Example 3 has the same notches as Example 3. The tire of Conventional Example 4 has the same patte...
