ABSTRACT:
Provided is an ultra-low profile pneumatic radial tire for SUV or the like having an aspect ration of 55% or less and a tire outer diameter of 720 mm or more, which has improved load durability while managing a weight reduction without deteriorating driveability. A carcass layer (4) thereof is configured as a single ply, and both ends thereof are folded back around left and right bead cores (7) so as to wrap bead fillers (8). A folded-back portion (4t) is wrapped on the inner side of an end of a belt layer (5) in a range not greater than 10% of the maximum width of the belt layer (5). The hardness of the bead fillers is 65 to 80 in terms of JIS durometer A hardness, and a height hb of the bead fillers (8) from a bead base is brought to 10 to 20% of the height H of a tire cross-section.
