PROBLEM TO BE SOLVED: To provide a tire for further improving steering stability without increasing the weight of the tire. SOLUTION: The pneumatic tire 1 includes a pair of bead parts 10 including at least a bead core 10a and a bead filler 10b, a carcass layer 20 provided from one bead part 10 to the other bead part 10, and a reinforcement layer 30 extending outward in a tire diametrical direction along the bead filler 10b. An end part 32 that is an end part on the inner side in the tire diametrical direction of the reinforcement layer 30 is positioned at the outer side in the tire diametrical direction than a rim base line BL that is a reference line indicating the end part on the outer side in the tire diametrical direction of the rim to which the pneumatic tire 1 is mounted. The end part 34 that is an end part on the outer side in the tire diametrical direction of the reinforcement layer 30 is positioned in the range of 55% or less to the cross section height H1 of the tire.
