TIRE WITH VARIABLE SHEAR ELEMENT
20220040943 · 2022-02-10 ·

A tire includes a central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.

PNEUMATIC TIRE

The present invention provides a pneumatic tire that can improve wet grip performance while maintaining a good TGC resistance, even when the tire is stored as having a thin thickness of a subtread at a bottom of a tread main groove, and rim-assembled and mounted on a vehicle to be left to stand. The present invention relates to a pneumatic tire comprising a tread part, the tread part comprising at least a cap tread and a jointless band, the cap tread being formed of a rubber composition for a cap tread, the jointless band comprising fiber cords coated with a rubber composition for fiber cord toppings, the rubber composition for a cap tread comprising 3.0 parts by mass or more of antioxidant based on 100 parts by mass of a rubber component comprising a diene-based rubber, and wherein a subtread thickness at the bottom of tread main grooves is 0.1 to 3.0 mm

Pneumatic tire

The pneumatic tire according to the disclosure includes a resin-coated belt comprising a wire coated with a coating resin. A base ring is formed at a tire radial inside of the resin-coated belt, while being in contact with a tire widthwise outer end of the resin-coated belt. A concavo-convex portion is formed on at least one of surfaces of the base ring.
