Latest Patents

**Studless tire with shaped tread blocks.** This design gives each tread block a narrow center portion and wider portions toward the heel and toe edges. The center’s minimum width is specified relative to the maximum widths of the two outer portions. Under braking or driving forces, the geometry is intended to increase apparent block rigidity, limit edge lifting, and reduce uneven wear.

**Studless tire with peripheral sub-blocks.** This tread pattern uses blocks defined by longitudinal and transverse grooves, including rows extending around the tire. Within a tread-pattern pitch, a sub-block sits outside an adjacent block along the tire’s rotating axle. A shallower sub-groove separates the sub-block from the main block, and the sub-block’s longer side runs in the tire’s peripheral direction.

Career Highlights

Mineta’s listed inventions focus on studless tire tread structures. The designs address how block shape, groove depth, and sub-block placement can influence tread behavior under driving forces.

Collaborations

Mineta is associated with Sumitomo Rubber Industries Limited. The supplied information also names Akihiro Miyoshi and Kenji Hatakenaka as coworkers.

Conclusion

Kenichi Mineta’s listed patent work centers on studless tire designs that use tread geometry to support block rigidity and manage wear.
