Abstract

To improve biased abrasion or traction and brake performance of a pneumatic tire formed with a great number of blocks partitioned by the main circumferential grooves and transverse grooves on the tread thereof, each of the block is formed with at least three sipes arranged regular intervals along the tire circumferential direction and extending over an entire width of each block along the tire transverse direction in such a way that at least one end of each sipe is open to the main circumferential groove and a central sipe of each block is formed the deepest as compared with other side sipes.
