PNEUMATIC TIRE

The present invention relates to a pneumatic tire. A rim diameter RD is 10 to 18 inches. A ratio SH/SW of a cross-sectional height SH to a cross-sectional width SW is 0.30 to 0.45. A ratio RW/SW of a rim width RW to the cross-sectional width SW is 0.78 to 0.99. A width W1 (mm) of a tread surface of a first shoulder land portion 11 satisfies expression (1) described below. The width W1 (mm), a thickness T1 (mm) of a first rubber layer 21, a thickness T2 (mm) of a second rubber layer 22, a loss tangent tanδ1 at 30°C of the first rubber layer 21, and a loss tangent tan62 at 70°C of the second rubber layer 22 satisfy expression (2) described below.
