A pneumatic bicycle tire to be operated with an inner tube includes a tread and two sidewalls. A bead is connected to a free end of each one of the sidewalls for mounting the tire on a wheel rim with rim flanges having a maximum standard height limit. Each bead has a bead core. A carcass is embedded in the tire and extends between the beads, wherein free ends of the carcass are wound about the beads. The carcass includes at least one ply. A padding strip is embedded in each sidewall in the vicinity of the beads. The padding strip is positioned along a curved section of the sidewall. The curved section begins at a center of the bead core and has a length equal to 40% to 210% of the maximum standard height limit. The padding strip has a hardness of between 40 and 60 Shore A, a rebound resilience of below 80% measured at a frequency of 2,000 Hz, and a thickness of at least 0.6 mm.

A rubber article has a rubber base body and a non-black areal member attached to the surface of the rubber base body. The rubber base body is made of a rubber compound containing at least one a basic, amino-group containing, aromatic anti-oxidant. The non-black areal member contains inorganic acidic components.

A method and apparatus for bonding a carcass for a tubed tire with a belt band that protects the radially inner side of the tire. The bonding surface is coated with a rubber solution, the belt band is placed thereon, and the bonding zone of tire and belt band is vulcanized. To achieve an increased resistance to separation between a biased carcass and a belt band, the zenith portion of the tire is reinforced with additional or overlapping plies in such a way that the rigidity of the outer half in the circumferential direction is greater than that of the inner half. While avoiding high speed accelerators, the rubber solution is provided with such a quantity of polymerizing agent that at the selected vulcanization temperature a vulcanizing time of between a third of a minute and ten minutes results. The tire, which is provided with the belt band and is in a position of use, is disposed onto a ring that is provided with a circumferential trough and is heated. The tire is inflated to shrink its circumference and to compress the bond that is to be vulcanized with the belt band.
