Safety pneumatic tire with tire maximum width to rim width ratio from 1.0 to 1.3

A safety pneumatic tire comprising at least one toroidal-shaped carcass ply composed of a rubberized cord layer, a pair of bead portions each including a bead wire, each having an end of said carcass ply wound around from the inside toward the outside thereof to form a turn-up portion;

• a pair of sidewall portions each connected to each bead portion;
• a tread portion extending across both said sidewall portions;
• an annular resilient reinforcing body extending along a total curved region from a position where the thickness of said bead portion becomes thin toward said sidewall portion to a hump position where the thickness at the shoulder of said tread portion is the largest, said annular resilient reinforcing body having a maximum thickness corresponding to 4 to 9% of the tire maximum width, said annular resilient reinforcing body gradually decreasing in thickness toward both said bead portion and said hump position, the total thickness of said annular resilient reinforcing body and said sidewall portion being substantially equal and continuous in the radial direction of the tire, said annular resilient reinforcing body having a JIS hardness of at least 60.degree.;
• and a ratio of the tire maximum width TW of said safety pneumatic tire mounted on a wheel rim and inflated under a given internal pressure applied in the tire to the rim width RW within a range given by 1.0.ltoreq.TW/RW.ltoreq.1.3.
