Low-flat wide-base all-steel radial tire

Abstract

The application discloses a kind of low flat wide base full steel radial tire, it is related to radial tire field, including tire tread and four layers belt layer, four layers belt layer includes first belt layer, second belt layer, third belt layer and fourth belt layer, the tire axial section profile of tire tread is sequentially smoothly connected by n section tread arc and is formed, n≥6, n section tread arc is respectively along tread center point symmetry distribution, the axial horizontal width of n section tread arc is respectively L1, L2, L3…L n , the width of tire tread is L, the application simple structure, by optimizing tread profile and belt layer structure simultaneously, increase the modulus of belt layer glue material while control the thickness ratio of tread and shoulder, can reduce tire belt layer endpoint shear strain, while guaranteeing tire ground shape uniform, improve tire endurance, to reduce tire failure rate.
