Latest Patents

One of Matsui's latest patents is for a run-flat tire. This tire is designed to reduce weight while enhancing uniformity. It features a toroidal carcass that extends from the tread portion to the bead core of each bead portion through the sidewall portions. Additionally, it includes a pair of side reinforcing rubbers arranged inside the carcass, extending along the sidewall portions in both the inward and outward radial directions. The tread portion's outer surface is equipped with pattern elements that form a pitch pattern. Each side reinforcing rubber has circumferentially spaced recesses on its inner surface, with the total number of recesses being 0.70 to 1.30 times the total number of pattern elements.

Another significant patent is for a pneumatic tire. This tire includes a wheel rim protector in at least one of its sidewall portions. The protector overhangs the flange of a wheel rim and protrudes axially outwardly from the axially outer end of the flange. It is designed with at least one circumferential slit around the tire's axis. If the slit extends continuously in the circumferential direction, it can be formed in a wedge-shaped cross-section. For discontinuous slits, they are arranged around the tire axis and inclined at angles of 45 to 80 degrees with respect to the adjacent carcass cords.
