To provide a pneumatic tire solving such a problem held by a prior art and superior in anti-hydroplaning property and operation stability performance on a dry road in addition to performance on snow and ice.
In the pneumatic tire having a wide circumferential main groove extending in a circumferential direction of a tread on a tread stepping surface of the tire, in a cross section in a width direction of the tire, length SWHout of a perpendicular taken down from the maximum width position to a tire rotation axis of an area becoming a vehicle outside at attachment of the vehicle making an equator surface of the tire as a border is made longer than length SWHin of a perpendicular taken down from the maximum width position to the tire rotation axis, and further, the circumferential main groove is arranged such that a width center of the groove is positioned at an inner side of the vehicle at attachment of the vehicle than an equator of the tire.
