DRIVE
September 18, 2024
A tire comprises a tread portion provided with circumferential grooves and including a circumferential first land portion and a circumferential second land portion on the tire equator side of the first land portion. Each of the first land portion and the second land portion comprises a cap tread rubber layer and an intermediate tread rubber layer. The loss tangent δ2 of the intermediate tread rubber layer is larger than the loss tangent δ1 of the cap tread rubber layer. The shortest distance L2 from the ground contacting surface of the second land portion to the radially outer surface of the intermediate tread rubber layer of the second land portion is smaller than the shortest distance L1 from the ground contacting surface of the first land portion to the radially outer surface of the intermediate tread rubber layer of the first land portion.
