一种抗压性强的外胎
By interlacing rigid rubber strips inside the tire shoulder area and adding high-carbon alloy steel wires to the tire sidewall area, the problems of stress concentration and insufficient shear resistance in the tire are solved, achieving smooth load transfer and improved airtightness, thus enhancing the tire's pressure resistance and durability.

AI Technical Summary
Traditional tires have an unreasonable thickness design in the shoulder area, resulting in stress concentration and insufficient shear resistance. They cannot effectively disperse the stress concentration in the shoulder and the shear resistance of the sidewall is insufficient. In the existing technology, the unreasonable thickness design in the shoulder area leads to rubber cracking or insufficient shear resistance.
By arranging rigid rubber strips in a staggered pattern on the inside of the tire shoulder area to form a honeycomb pattern, and combining it with high-modulus butyl rubber material, the shear strength is improved. At the same time, high-carbon alloy steel wire and a ring locking structure are added to the sidewall area to enhance air tightness and anti-beading ability.
It achieves a smooth transfer of tread load to the sidewall, avoids stress concentration, improves the shear resistance and airtightness of the tire shoulder, enhances the anti-beading ability, and improves the overall pressure resistance and durability of the tire.
