Abstract
A pneumatic tire comprises a plurality of main grooves in a tread of a tire. The main grooves substantially circumferentially extend and are spaced apart from each other in an axial direction of the tire. Each the main grooves is continuous. Intersection angles between an equatorial plane of the tire and tangents to each the main grooves are larger from a starting end to a terminal end of the main groove opening at a tread end of the tire. The pneumatic tire further comprises a plurality of sipes in a tread of the tire. The sipes extend substantially in axial directions of the tire but are inclined relative to the equatorial plane of the tire and spaced apart from each other in circumferential directions. Each the sipe is inclined with its opening directing forward in a rotating direction of the tire.
