摘要： A tread (1) for a heavy goods vehicle tyre, having a total width W and being provided with two main circumferential grooves (2) dividing the tread (1) into a middle region (M) and two side regions (B) axially to either side of the middle region, the middle region (M) having an axial width Lm of between 45% and 70% of total width W, the hollow rate by volume of the tread in new condition is less than 17%, said hollow rate being the ratio between the total hollow volume and a total volume including all hollow spaces and assessed between the rolling surface in new condition and an inner surface extending parallel to the rolling surface in contact with the bottoms of the main grooves (2), the middle portion comprising a plurality of transverse incisions (6), the depth of which is at least equal to the depth of the main grooves (2) and opening into these grooves, this tread (1) being such that the middle region has a hollow rate by volume that is less than half the total hollow rate by volume of the tread, and at least one continuous circumferential channel is formed under the rolling surface in new condition, in order to appear after partial wearing of the tread.

摘要： A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

摘要： A method and apparatus for shielding critical faster-moving upper wheel surfaces from headwinds reduces vehicle propulsive counterforces needed to countervail mechanically magnified upper wheel drag forces combined with drag forces on the apparatus itself. The apparatus includes various upper wheel fairings of FIGS. 1-6. Each fairing shields a critical primary vehicle-drag-inducing upper wheel surface from headwinds otherwise impinging thereon.

摘要： Tire treads, having one or more repeating pitches, each repeating pitch comprising individual pitches having tread blocks with sipes formed therein and each pitch having a pitch length of between 15 mm and 35 mm. Such treads may also have a weighted, average sipe density D
w of between 10 mm
-1 and 37 mm
-1 , which is determined through the disclosed Eq. 2 below. The tread blocks are also formed from a rubber composition based upon a diene elastomer, a plasticizing system and a cross-linking system, wherein the rubber composition has a glass transition temperature of between -40° C and -15° C and a shear modulus G* measured at 60 ° C of between 0,5 MPa and 1,1 MPa.-

摘要： A tire has a circumferential tread, the tread (10) including shoulder tread regions (16, 18) configured for off-road performance separated by and interlocking with a center tread region (14) configured for on-road performance. The shoulder tread regions are defined by a repeating pattern of two or more distinct shoulder tread elements (4, 5) and the center tread region is defined by a repeating pattern of two or more distinct center tread elements (1, 2, 3). The shoulder tread elements each have a ground contacting surface area greater than a ground contacting surface area of the center tread elements.
