QUICK CHANGE-REPLACEABLE TREAD PNEUMATIC TIRE

摘要

A vehicular wheel and pneumatic tire assembly including a wheel portion, a tire-carcass portion and a separate tread band portion installed over the uninflated carcass-periphery, and in which the carcass portion is molded into a convoluted shape, when uninflated, that provides its easy stretching over the outside diameter of the wheel and, on application of an inflation pressure, simultaneously ensures both the outward expansion of the carcass-periphery and the inward contraction of the carcass-inside diameter for respective tight-fitting engagement with, and assembly to, the tread band and wheel portions.
