Abstract
A pneumatic tirehaving a toroidal carcassextending from a tread portionthrough a sidewall portionto a bead corein a bead portion, is provided in the bead portionwith a bead reinforcing rubber layeralong an outer surface in the tire axial direction of the carcass. The bead reinforcing rubber layeris formed from a band-like rubber stripwound spirally circumferentially of the tire. In a tire meridian section including the tire rotational axis, each of the inner surface Si and the outer surface So in the tire axial direction of bead reinforcing rubber layerhas adjacent rubber strip's interfaces, and the number of the interfaceson the inner surface Si is smaller than the number of the interfacesin the outer surface So.
