TIRE
DRIVE
September 21, 2023
A pneumatic tire includes a circumferential main groove extending in a tire circumferential direction, a land portion defined by the circumferential main grooves, and a sipe disposed in the land portion. The sipe is formed in a zigzag shape that has an amplitude in a width direction of the sipe while extending in a longitudinal direction of the sipe. A magnitude of the amplitude changes according to a position in a depth direction of the sipe. A depth of a maximum amplitude portion from an opening portion of the sipe in the depth direction of the sipe is located at a position 30% or more of a maximum depth of the sipe. The maximum amplitude portion is a portion where a magnitude of the amplitude is maximum.
