Abstract
To improve durability performance and rolling resistance performance in a well-balanced manner. It is a tire for heavy loads including a carcass ply (A). A sidewall rubber (G) includes an inside rubber part () on the carcass () side, and an outside rubber part () disposed on the outside thereof and forming a tire outer surface. The inside rubber part () has a loss tangent tan δ1 less than the outside rubber part (), and their difference is 0.010 to 0.035. The inside rubber part () has a complex elastic modulus less than the outside rubber part (), their difference is 0.5 to 1.4 (MPa). The outer end () in the tire radial direction of the inside rubber part () contacts with the outer surface () in the tire axial direction of the tread rubber (G), and the inner end () in the tire radial direction is disposed radially inside the outer end () in the tire radial direction of the turned up portion () of the carcass ply (A).
