Embodiment Construction
[0015] The present invention will be further described below in conjunction with specific drawings.
[0016] Such as Figure 4 As shown: the full-divided pre-seal of the all-steel radial tire tread is a centrally symmetrical structure, including the lower shoulder rubber channel 1 and the upper tread rubber channel 2; the lower shoulder rubber channel 1 is from left to right Through, and the height of the middle part of the shoulder rubber channel 1 is smaller than the height of the two sides, so that the two sides of the shoulder rubber channel 1 are used to form the shoulder rubber layer 3 on both sides of the tire tread, and the middle of the shoulder rubber channel 1 The part is used to form the transitional shoulder adhesive layer 4 between the shoulder adhesive layers 3 on both sides, such as Figure 5 shown;
[0017] Such as Figure 4 As shown, the height of the middle part of the tread rubber channel 2 is 27 mm, and the width of the middle part of the shoulder rubbe...
