Tire shoulder structure of semi-steel agricultural radial tire

The utility model relates to the technical field of tires, in particular to a tire shoulder structure of a semi-steel agricultural radial tire. A pattern groove is formed between the adjacent pattern blocks on the same side, the bottom of the pattern groove is of a stepped structure, an obtuse angle is arranged at the joint of the stepped structure, and the obtuse angle is larger than 90 degrees and smaller than or equal to 170 degrees. The tire is used for agricultural harvesters and agricultural machinery with other purposes, can effectively provide sufficient load capacity, is more reasonable in tire shoulder material distribution, uniform in steel wire belt layer distribution and balanced in stress, effectively reduces the defects of tire shoulder vacancy, delamination and the like, provides more uniform grounding pressure, reduces the phenomenon of irregular abrasion of pattern blocks, and improves the service life of the tire. Therefore, the service life of the tire is prolonged. 本实用新型涉及轮胎技术领域，具体涉及一种半钢农
