Abstract: The invention relates to a two-wheeled vehicle pneumatic tire (1), preferably bicycle tire, particularly preferably racing bike tire (1), having a tread (2), a tire carcass, tire side walls (3) and two bead regions (4), each with a tire bead with a core (5), wherein the tire carcass comprises two carcass inlays (6,6′) wherein the two carcass inlays (6, 6′) extend from a zenith region (17) of the two-wheeled vehicle pneumatic tire (1) over the tire side walls (3) as far as the two bead regions (4) and are looped there around the respective core (5) from axially on the inside axially outward and end with carcass inlay ends (7,7′) and wherein the two bead regions (4) each have a bead protective strip (8) arranged on the carcass from the outside as protection against chafing.
The problem addressed is that of improving the rolling resistance.
The problem is solved in that the carcass inlay ends (7′) of the inner carcass inlay (6′) are covered from the outside by the respective bead protective strip (8), wherein the inner carcass inlay (6′) is formed by that carcass inlay of the two carcass inlays (6, 6′) which is the radially inner carcass inlay in the zenith region (17). The invention furthermore relates to a two-wheeled vehicle having a tire of said type.

Abstract: A recessed portion is formed in each tire side portion of an agricultural machinery pneumatic tire. Rigidity at the part of each tire side portion where the recessed portion is formed is reduced. This enables each tire radial direction outside portion to be made to tilt over toward tire width direction outside with the recessed portion as a point of origin without reducing the internal pressure, enabling the ground contact width of a tread portion to be enlarged. Since there is no need to intentionally reduce the internal pressure in order to reduce the ground contact pressure, bead portions do not tilt over more than necessary, and there is no reduction in the durability of the bead portions.

Abstract translation: 在农业机械充气轮胎的各轮胎侧部形成有凹部。 形成有凹部的轮胎侧部的部分处的刚性降低。 由此，能够使轮胎径向外侧部分的轮胎宽度方向外侧以凹部为原点倾斜，而不会降低内压，能够扩大胎面部的接地宽度。 由于不需要有意地降低内部压力以降低接地压力，胎圈部分不会超过必要倾斜，并且胎圈部分的耐久性不会降低。
