Abstract
A pneumatic safety tire in which each sidewall portion is provided with a minimum thickness at a position E between an outer edge point A and a 65% height point B both located on each side of the tire equator, where the outer edge points A are defined as the axially outer edges of a ground contacting region on the tread surface in a standard loaded state in which the tire mounted on a regular rim and inflated to a regular pressure is loaded with a regular load, and the 65% height points B are defined as the positions at 65% height of the tire section height H from the bead base in a standard unloaded state in which the tire mounted on the regular rim and inflated to the regular pressure is kept free of load, and further the thickness of each sidewall portion is gradually increased from the minimum thickness position E toward the 65% height point B.
