Abstract
A pneumatic tire has a bead filler, a carcass ply, a side wall rubber and a rim strip rubber. The rim strip rubber has a main portion arranged in an outer side in a tire width direction of the bead filler, and a thin portion arranged between the carcass ply and the side wall rubber. The main portion forms an outer surface of a bead portion. The thin portion extends in the tire diametrical direction at a substantially fixed thickness. An upper end of the thin portion is positioned in an outer side in the tire diametrical direction than an upper end of the bead filler and in an inner side in the tire diametrical direction than a roll-up end of the carcass ply.
