Abstract
When a tire that is mounted on a specified rim, inflated to an internal pressure of 50 kPa, and placed in a no-load state is viewed as a cross-section from the tire meridian direction, a position of 1.30×Hf on an outer surface of a sidewall portion, taking a rim flange height (Hf) of the specified rim as a reference, is defined as a point (P), a foot of a normal line (L) drawn from the point (P) to a carcass line of a main body portion () of a carcass layer () is defined as a point (M), and a point of intersection of the normal line (L) and a carcass line of a folded back portion () of the carcass layer () is defined as a point (T). At this time, a distance (a) mm from the point (M) to the point (T), a distance (b) mm from the point (T) to the point (P), and a specified load (x) kN have relationships such that a=0.019×x+13.3 and b=0.052×x+21.6, with a tolerance of not less than 0% and not more than 20%.
