Abstract

The object of the present invention is to improve the wear resistance of tires, especially in truck and bus tires (TBR tires), to improve the resistance to the heel and toe (Heel & Toe) of the tread block. Rules fray. For this reason, the present invention provides a kind of pneumatic tire, and it comprises tread (100), sidewall (sidewall) and tire bead, and pattern block (200) and groove (groove) are formed on the tread (100). ) (300), in the groove (300) connected to the pattern block (200), a ground contact pressure reducing pattern block (400) is arranged adjacent to the tail portion 210 in the forward direction.

Description

technical field [0001] The present invention relates to a pneumatic tire with improved wear resistance, and more particularly to a tire for trucks and buses (TBR (Truck Bus Rubber) tire) in which irregular wear of tire heels and tire toes (Heel & Toe) of tread blocks is obtained. Improved pneumatic tires. Background technique [0002] In pneumatic tires for vehicles, especially tires for trucks and buses (TBR), heel and toe wear often occurs as one of irregular wear of blocks on the tread. Tire heel and tire toe (Heel&Toe) wear means that in a truck and bus (TBR) tire with a block pattern (Block Type Pattern), in a block, the wear of the first contact with the ground is less than that of the later contact with the ground The part of the wear phenomenon, wherein the guide part of the block as the part with less wear is called the heel (Heel), and the tail part as the part with more wear is called the toe (Toe). [0003] In general, in order to reduce the wear of the above-m...
