PROBLEM TO BE SOLVED: To provide a pneumatic tire for heavy load holding high maneuvering stability and abrasion resistance and reducing the rolling resistance. SOLUTION: This tire is so constituted that a tread rubber has a three-layer or more laminated rubber constitution, the laminated rubber has a deformation suppressing rubber layer of high modulus and a body rubber layer sandwiching the deformation suppressing rubber layer in the tire radius direction between the outside and the inside, and the body rubber layer has a lower modulus physical property compared with that of the deformation suppression rubber layer.
