PNEUMATIC RADIAL TIRE

摘要

Land rows (2) are formed on the tread of a tire by main grooves extending in the circumferential direction of the tire. A thin groove (3) is formed in at least one shoulder land row (2A) of the land rows which is located on the side of a tread end. A land (5) located between the thin groove (3) and the tread end (4) is divided into blocks (5a) by lug grooves (6) extending in the lateral direction of the tire and whose maximum depth is set deeper than the depth of the thin groove (3). The depth of the lug grooves is continuously varied so as to be maximum at an intermediate position between the thin groove and the tread end. The pneumatic radial tire has improved water discharge performance.
