Abstract:
In a cross section view in a tire meridian direction of a tire which is mounted on a regulation rim, filled with an internal pressure of 50[kPa], and placed in no-load state, a point (P) is taken at a position of 1.30 × Hf on an outer surface of a sidewall portion with reference to a rim flange height (Hf) of the regulation rim, a leg of a normal (L) drawn from the point (P) to a carcass line of a body portion (131) of a carcass layer (13) is defined as a point (M), and a point of intersection of the normal (L) and a carcass line of a roll-back portion (132) of the carcass layer (13) is defined as a point (T). 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 regulation load (x) [kN] have the relationships a = 0.019 × x + 13.3 and b = 0.052 × x + 21.6, with a tolerance of 0[%] or more and 20[%] or less.
