Early pneumatic tyre, use is made of coated with rubber canvas when tire body, because the canvas ordinate and horizontal lines cross each other, due to the deformation of the tire when walking, lead to rub against each other, in this way, the line is easy to be ground breaking, the tires can only run 200-300 km. In 1903, Mr. J. f. palmer invented the twill textile, which led to the development of cross - layer tires, making the tyre life a big step forward. Because the tire of the skew fork will no longer cause friction because of the tread of the tyre, the cord will not be easily worn out, so the life span will be considerably longer.
