Abstract
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.
