Latest Patents

Fujishiro’s latest listed patents address tire structures and performance.

The first patent describes a tire with an outer diameter of 200 to 660 mm and a total width of 100 to 400 mm. Its carcass layer consists of two plies made with organic fiber cords covered by rubber. The cords are oriented at angles from 80 to 100 degrees relative to the tire’s circumferential direction, and the patent specifies a range for each ply’s tensile strength in relation to the tire’s outer diameter.

The second patent concerns tread-groove distribution. It describes a tire with an outer diameter of 200 to 660 mm and a total width of 100 to 400 mm, with limits on the tread’s overall groove area ratio. It also defines inner and outer tread regions and specifies that the groove area ratio in the inner region is lower than in the outer region.
