Abstract:
A pneumatic tire comprising:a carcass layer provided between a pair of left and right bead sections;left and right side wall sections interpolated for connecting said pair of left and right bead sections with a tread section to be continuous; andat least two belt layers provided in an outer peripheral side of said carcass layer in said tread section, each of said belt layers being composed of a plurality of reinforcing cords coated with coating rubber,wherein storage elastic modulus E' of said coating rubber is set in a range of 15.0 to 40.0 MPa, its loss tangent tan .delta. is set in a range of 0.1 to 0.25, interlayer rubber is provided between end parts of said belt layers, said interlayer rubber being specifically set in each of both end parts thereof in a tire width direction, and elongation to break Eb of said interlayer rubber is set in a range of 400 to 700%, storage modulus E' and loss tangent tan .delta. being measured at a frequency of 20 Hz, an initial strain of 10%, a dynamic strain of .+-.2%, and a temperature of 60.degree.
