Abstract: A tire comprising a tread portion for contacting the ground and a pair of opposing sidewall portions, the tread portion extending between a pair of shoulders and having an equatorial region in between, the sidewall portions extending essentially in a radial direction from the shoulders, wherein the tread portion comprises next to the shoulder at least one circumferential groove forming a recessed rib, the recessed rib located on the side of the circumferential groove farther away from the equatorial region, said groove has adjacent groove walls with a first groove wall facing away from the equatorial region and a second groove wall facing towards the equatorial region, the second groove wall comprises a protruding portion protruding outwardly away from the equatorial region comprising two diverging regions and in between the diverging regions a non-diverging region, the diverging region on the second groove wall is non-parallel to the first groove wall.

Abstract: The disclosure relates to a silica embedded carbon black composite aggregate prepared by a method comprising: a) feeding an oxidative gas, silica precursor and carbon black feedstock to a mixing chamber of a reactor assembly; b) mixing the oxidative gas, silica precursor and carbon black feedstock in the mixing chamber to obtain a pre-mixed blended feedstock; c) injecting the pre-mixed blended feedstock into a flame burner of the reactor assembly, the flame burner being operably connected to the mixing chamber; d) generating heat of combustion through partial oxidative burning of the pre-mixed blended feedstock to attain reactor thermal conditions; and e) cracking the pre-mixed blended feedstock to produce in-situ formed silica embedded carbon black composite aggregate, wherein weight percent of the embedded silica particle in the composite aggregate is in a range of from about 30% to about 60%.

Abstract: An assembly comprising a tyre valve (2) and an enclosure (3), wherein the enclosure (3) is adapted to receive a gas pressure monitoring unit, wherein the enclosure (3) comprises a hinge joint, the hinge joint having at least one stationary member connected to the enclosure (3), an axle (6) and a rotatable member (4) arranged to at least partially rotate around the axle (6) and wherein the tyre valve (2) is connected to the rotatable member (5) of the hinge joint. The tyre valve (2) is connected to the rotatable member (4) of the hinge joint by a form-fitting connection which secures the tyre valve (2) against movement in a direction towards the rotatable member (4) and in a direction away from the rotatable member (5).
