Abstract
A tire can include a pair of beads, a carcass, a pair of protective rubber layers, and a pair of reinforcing rubber layers. A carcass ply of the carcass can include a ply body and a pair of turned-up portions. Each reinforcing rubber layer can be between the turned-up portion and the protective rubber layer. An outer end of an apex of each bead can be between an outer end and an inner end of the reinforcing rubber layer in a radial direction. A thickness of the protective rubber layer in a zone from a rim contact end to the outer end of the reinforcing rubber layer can be small at a center portion in the radial direction of the reinforcing rubber layer and can be large at another portion.
