NON-PNEUMATIC TIRE
In a non-pneumatic tire according to the present invention, a plurality of curved portions (21d to 21f and 22d to 22f) curved in a tire circumferential direction are formed on elastic coupling plates (21 and 22) in an extending direction in which the elastic coupling plates (21 and 22) extend in a tire side view when the non-pneumatic tire 1 is viewed from a tire width direction, curvature directions of the curved portions (21d to 21f and 22d to 22f) adjacent to each other in the extending direction are opposite to each other, the size or thickness in the tire width direction and a transverse section area of the elastic coupling plates (21 and 22) are the minimum at one of a plurality of inflection portions (21g, 21h, 22g, and 22h) positioned between curved portions adjacent to each other in the extending direction of the elastic coupling plates (21 and 22), and the size or thickness in the tire width direction and the transverse section area of the elastic coupling plates (21 and 22) gradually decrease in the extending direction from opposite sides toward one inflection portion (21h and 22h).
WHEEL AND TIRE ASSEMBLY
A wheel assembly includes a rigid wheel and an airless flexible tire with certain performance characteristics of a pneumatic tire. The rigid wheel includes a central portion and a plurality of circumferentially spaced mounting elements removably attached to a radially outer margin of the central portion. The tire is mounted on the wheel and engages the mounting elements such that portions of the tire not engaging the mounting elements are separated radially from the wheel by a space. The tire is configured such that portions of the tire not engaging the mounting elements flex inwardly toward the wheel when subject to ground engaging pressure, thereby minimizing ground penetration and soil disruption. The tire may include one or more tension elements embedded in the tire to increase the tire's strength and resilience.

SOLID TIRE PERFORMANCE SENSING SYSTEM AND METHOD
In accordance with presently disclosed embodiments, a tire monitoring system is provided. The tire monitoring system utilizes a heat sensor embedded in a solid rubber tire. The heat sensor detects a temperature of the solid tire, and a transmission system transmits signals indicative of the temperature from the heat sensor to a remote monitoring system. The remote monitoring system may monitor the temperature of the solid tire and output notifications to alert a user when preventive maintenance is needed. The heat sensor may be embedded in the solid rubber tire during the manufacture of the solid tire, or the heat sensor may be embedded into the solid tire after production of the tire is complete. The system may be used track cure time and temperature as the tire is being produced and/or to log tire performance information throughout the operation of the tire.

NON-PNEUMATIC TIRE
The present invention provides a non-pneumatic tire which is provided with an attachment body (11) attached to an axle, a ring-shaped body (13) which surrounds the attachment body (11) from the outside in a tire radial direction, and a coupling member (15) which displaceably couples the attachment body (11) and the ring-shaped body (13), wherein the coupling member (15) is formed of a synthetic resin material and a reinforcing member is embedded in the coupling member (15).
Non-pneumatic tire
A non-pneumatic tire (1) includes three or more tubular bodies (2) and a plurality of elastically deformable connecting members (3) interconnecting the tubular bodies (2) and disposed along a tire circumferential direction in each annular space (9) provided between the tubular bodies (2) adjacent to each other in a tire radial direction. The tubular bodies (2) are provided with an inner tube (6) positioned on an innermost side in the tire radial direction and attached to an axle, an outer tube (4) positioned on an outermost side in the tire radial direction, and an elastically deformable intermediate tube (8) positioned between the inner tube (6) and the outer tube (4). The connecting member (3) is provided with a pair of connecting plates (21 and 22) having both end portions in the tire radial direction directly connected to the tubular body (2) and extending in the tire radial direction and separated in the tire circumferential direction from an outside toward an inside in the tire radial direction. A position (P1) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the outside in the tire radial direction and a position (P2) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the inside in the tire radial direction are shifted in the tire circumferential direction in the intermediate tube (8).
Pneumatic tire
A pneumatic tire includes a tread portion provided with a pair of shoulder main grooves and at least one crown main groove between the shoulder main grooves to define a pair of middle portions between the adjacent shoulder main groove and crown main groove. The middle portions are provided with inner middle lug grooves and outer middle lug grooves. Each outer middle lug groove extends from the shoulder main groove to its axially inner end while decreasing its groove width. The outer middle lug groove are arranged with alternately arranged first pitches and second pitches, wherein the second pitches are larger than the first pitches. Each inner middle lug groove extends from the crown main groove to its axially outer end while decreasing its groove width. The inner middle lug grooves are arranged with substantially the same pitches.

SHEAR BAND CONSTRUCTION
A shear band for a tire includes an annular first, radially outer fabric layer extending circumferentially around the tire; and an annular second, radially inner fabric layer extending circumferentially around the tire. The shear band is formed from a single shear band strip helically wound circumferentially and axially with a first edge of the shear band strip. The first edge of the shear band strip has a first extension flap for engaging an opposite second edge of the shear band strip. The first extension flap is continuously secured to the opposite second edge linearly along the opposite second edge of the shear band strip.
