<p>Provided is a studless tire capable of achieving both the traction performance and the steering stability at the time of traveling on the ice and snow at a high level. A tread surface 10 is disposed on the studless tire such that, among lateral grooves 3A, 3B, 3C, 3D, 5 extending in an axial direction within each block array 2A, 2B, 2C, 2D, an axial length of a lateral groove 3A, 3B, 3C, 3D opening to at least one straight circumferential groove 1, 1A, 1B adjacent to the block array provided with the lateral groove is referred to as a groove edge component, a proportion of the total length of the groove edge components on the inner tread surface IN to the total length of the groove edge components on the outer tread surface OUT is 1.03-1.3, and, a proportion of a negative ratio of the outer side surface OUT to a negative ratio of the inner side surface IN is 0.85-1.0.</p> |
