A tire includes a reinforcing rib formed on a groove to prevent irregular wear of a tread and including an auxiliary hidden groove formed in the groove to enhance capabilities of water absorption and drainage of the tire even when the reinforcing rib is formed on the groove. The tire can include a reinforcing rib coupled to a first sidewall, which is one of both sidewalls forming the groove, and protruding toward the groove from the first sidewall, a hidden groove formed in one portion of a second sidewall which is the other of the sidewalls forming the groove, and a remaining tread part protruding toward the groove from a side surface of the hidden groove, the remaining tread part being the other portion of the second sidewall.

Tire for preventing irregular tread wear

A tire that can attach and detach and that can prevent splash when running a wet road and cool discharging a heat is provided. The tire having a tread and a shoulder portion connected to the tread includes a protector portion provided in a circumferential direction at a side surface of the shoulder portion and in which a plurality of penetration portions are formed at a predetermined gap in a length direction; a plurality of protruding portions provided in the protector portion and formed at a predetermined gap in a length direction of the protector portion; and a plurality of installation grooves formed at a side surface of the shoulder portion such that the protruding portion attaches or detaches when the protruding portion enters or discharges.

Tire

Provided is a pneumatic tire which can fundamentally prevent the phenomenon in which cracks are generated in the bottoms of grooves and the areas where the side walls of blocks meet the bottoms of grooves, can suppress irregular abrasion of the tread, can enhance the overall rigidity of the tread, and can also enhance the drainage performance. The pneumatic tire of the invention includes a tread, side walls and bead sections, with a large number of blocks compartmentalized by grooves being formed on the surface of the tread, and also includes reinforcing ribs that are positioned inside a groove and have their lower parts joined with the bottom of the groove, with one lateral surface of a reinforcing rib and one side wall of the groove being in contact.
