A tread surface 20 of the tire 2 includes a center portion C and a pair of shoulder portions S. A contour line of the tread surface 20 is divided into ten parts. Among the ten parts, two parts including an equator PC are represented by arcs, and two parts including ends PE of the tread surface 20, respectively, are represented by arcs. A bank angle θb is larger than a camber angle θc. A ratio of a degree of curvature Bs of the shoulder portion S to a width TW of the tread surface 20 is not less than 50%. A ratio of a camber height d to a tire cross-sectional height H is not less than 50%.

Provided is a tire including a tread portion. The tread portion includes two circumferential grooves and three land portions. The three land portions include a crown land portion disposed on a tire equator, and two shoulder land portions including tread contact ends. At least one of the shoulder land portions includes a plurality of main inclined grooves and a plurality of subsidiary inclined grooves. The main inclined grooves have tire-axially inner ends ending in the shoulder land portions and tire-axially outer ends disposed outwardly of the tread contact ends Te in the tire axial direction. The subsidiary inclined grooves have tire-axially inner ends ending in the shoulder land portions and tire-axially outer ends ending in the shoulder land portions.

Systems for detection of tire strain in a vehicle are disclosed. In some implementations, the system may include an antennae disposed on one or more of the vehicle or a vehicle component and may output an electromagnetic ping. The system may include a tire with a body formed of one or more tire plies. Any one or more of the tire plies may include split-ring resonators (SRRs). Each SRR may have a natural resonance frequency that may proportionately shift in response to a change in an elastomeric property of a respective one or more tire plies, the elastomeric property including one or more of a reversible deformation, stress, or strain. The SRRs may include split-ring resonator (SRR) with carbon particles that may uniquely resonate in response to an electromagnetic ping based at least in part on a concentration level of the carbon particles within the SRR.

The present invention aims to provide tire rubber composition with significantly improved overall performance in terms of wet grip performance and fuel economy, and pneumatic tires including the rubber compositions. The tire rubber compositions of the present invention have a tan δ versus temperature curve whose peak tan δ and half width satisfy the following relationship (1): Peak tan δ/Half width ≥ 0.025 (1).

There is provided a non-pneumatic tire (1), which includes an attachment body (11) that is attached to an axle, a ring-shaped body (13) that surrounds the attachment body (11) from an outside in a tire radial direction, a connection member (15) that displaceably connects the attachment body (11) and the ring-shaped body (13) to each other, and a cylindrical tread member (16) that is externally mounted on the ring-shaped body (13), in which the tread member (16) includes a base rubber portion (41) that is positioned at an inside in the tire radial direction, and a cap rubber portion (42) that is positioned at an outside of the base rubber portion (41) in the tire radial direction, and in which the rigidity of the base rubber portion (41) is lower than the rigidity of the cap rubber portion (42).

A tire includes a tread, a crown with a crown reinforcement, first and second sidewalls, two beads, and a carcass reinforcement anchored to the two beads and extending from the first sidewall to the second sidewall. The tread includes a thermoplastic elastomer that is a block copolymer, which includes at least one elastomer block and at least one thermoplastic block. A total content of the thermoplastic elastomer in the tread is within a range varying from 65 to 100 phr (parts by weight per hundred parts of elastomer).

Heavy load pneumatic radial tire according to the present invention includes: tread rubber 6 having laminated structure of cap rubber 5 and base rubber 4; and four or more belt layers 3a-3e disposed radially inward of tread rubber 6. A radially outer side of a width direction side edge of at least one of radially outermost belt layer 3e and widest-width belt layer 3c is covered by reinforcing rubber layer 7 that terminates on a radially inner side of tread rubber 6 without reaching tire equatorial plane E. Relative relation between reinforcing rubber constituting reinforcing rubber layer 7 and base rubber 4 in terms of modulus of rebound elasticity satisfies the condition: reinforcing rubber<base rubber 4.

Provided are a sliding elastic body capable of imparting excellent sliding properties and resistance to protein adsorption and, at the same time, maintaining sealing properties; and a syringe gasket, a catheter, and a tire which include the sliding elastic body. The present invention relates to a sliding elastic body including an elastic body whose surface is fully or partially laminated with a fluororesin film, the laminated elastic body being treated with a fluorinated oil.
