A tire-wheel assembly comprises a wheel coupled to a rotating shaft; an elastic tube disposed on an outer side of the wheel with respect to a radial direction, the interior of the tube being filled with air; a rigid protective ring disposed on an outer side of the tube with respect to the radial direction separated from the wheel; and a tread ring disposed on an outer side of the protective ring with respect to the radial direction, an inner circumferential surface of the tread ring contacting an outer circumferential surface of the protective ring.

Tire/wheel assembly and tread ring

A pneumatic tire including a first row of blocks arranged in a substantially central region of a tread of the pneumatic tire, wherein the first row of blocks includes a plurality of first blocks; a plurality of first grooves, each arranged between two adjacent first blocks; a plurality of second rows of blocks each including a plurality of second blocks, each arranged on either side of the first row of blocks; a plurality of second grooves, each arranged between the first row of blocks and each of the second rows of blocks; and a plurality of third grooves, wherein each third groove is arranged between two adjacent second blocks, the third grooves including a plurality of fourth grooves and a plurality of fifth grooves, with each fourth groove being narrower than each fifth groove, and the fourth groove and fifth groove being arranged alternately.

Pneumatic tire and mold

Provided is a non-pneumatic tire in which buckling can be prevented without a weight increase, the non-pneumatic tire including a spoke structure. The spoke structure is obtained by circumferentially arranging spokes intermittently at intervals and coupling together annular cylindrical outer member and cylindrical inner. The spoke structure is joined to an inner peripheral side of a tread ring. At least some of a plurality of spaces formed between two spokes adjacent to each other in the tire circumferential direction have an air-containing structure.

Non-pneumatic tire

Automobile tire tread

Automobile tire

A non-pneumatic tire includes a spoke structure that can be easily mounted on a rim of a wheel. Durability is improved by suppressing the buckling of a spoke structure. A non-pneumatic tire includes a spoke structure () and a tread ring (). The spoke structure () includes a cylindrical outer member () and a cylindrical inner member () which are concentrically arranged, and which are connected to each other with a plurality of fins (') arranged at intervals in the circumferential direction. The tread ring () fits onto the outer periphery of the spoke structure (). The spoke structure () is divided in the tire circumferential direction into at least two circumferential-direction separate structures ().
