Abstract
In a tire including a block having an edge along a main groove closer to an equatorial plane and a block having an edge along a main groove farther from the equatorial plane, the angles between an imaginary line extending a ridge line formed by a bend point of a groove wall on the edge side of the main groove and imaginary lines extending each of edges adjacent in a circumferential direction with the edge interposed therebetween are an acute angle (θa) and an obtuse angle (θb), and the angles between an imaginary line extending a ridge line formed by a bend point of a groove wall on the edge side of the main groove and imaginary lines extending each of edges adjacent in the circumferential direction with the edge interposed therebetween are an acute angle (θc) and an obtuse angle (θd), with a relationship (θd−θc)<(θb−θa).
