Abstract
A pneumatic tire maintaining excellent traction performance for the entire life of the tire. The tire () has blocks () each demarcated by both a circumferential groove formed in the tread and lateral grooves crossing the circumferential groove, and also has recessed parts (). Each recessed part () is formed in at least one of those both wall surfaces of each block () that are oriented to the lateral direction of the tire, and the circumferential width (C) of each recessed part () is increased from the tread side of the block () toward the radially inside of the tire. Because the edge effect of the blocks () at the portions between the lateral grooves and the recessed parts () can be maintained in an excellent state even if the wear of the tire () progresses, the edge effect of the entire blocks can be maintained in an excellent state, and excellent traction performance can be maintained for the entire life of the tire.
