Summary:PROBLEM TO BE SOLVED: To enhance side-cut resistance of a pneumatic radial tire for a heavy load.SOLUTION: In a pneumatic radial tire 10 for a heavy load, a thickness AW1 on the tire mounting outside is set 1.2-3.0 times greater than a thickness AW2 on the tire mounting inside, in a side line part 14A in a position of a side part 14 corresponding to a point D1 on the outermost side in a tire width direction of a carcass body part 18A in the unloaded condition of being assembled to a normal rim and filled with normal internal pressure. 【課題】重荷重用空気入りラジアルタイヤにおける耐サイドカット性を高める。【解決手段】重荷重用空気入りラジアルタイヤ１０は、正規リムに組み付け正規内圧を充填した無負荷状態におけるカーカス本体部１８Ａのタイヤ幅方向の最外側のＤ１点に対応するサイド部１４の位置であるサイドライン部１４Ａにおいて、タイヤ装着外側の厚みＡＷ１をタイヤ装着内側の厚みＡＷ２の１．２倍〜３．０倍としている。【選択図】図１
