Abstract

The present invention provides a pneumatic tire for heavy vehicle comprising a tread part(1), a tire sidewall part(2), a bead part(3), a decoupling slot(4)formed between the tread part(1)and the tire shoulder part(10), wherein a sacrificial rib is formed at the interior center of the decoupling slot(4). Thus, the abnormal wear of the tire shoulder rib part can be prevented from generating, the reducing of road behavior of the tire after the wear metaphase can be prevented, the life of tire can be greatly prolonged.

Description

technical field

[0001] The present invention relates to a pneumatic tire for heavy loads, and more specifically, to a pneumatic tire for heavy loads capable of preventing abnormal wear of shoulder ribs. Background technique

[0002] In general, in pneumatic radial tires for trucks and buses, the wear performance and abnormal wear performance of the tire can be said to be the most important issues.

[0003] Radial tires for trucks can be roughly classified into a rib pattern and a block pattern according to the pattern shape of the tread portion.

[0004] Block tires have the advantage of making the braking performance of the vehicle better. The strip pattern tires make the handling performance and stability of the vehicle good, without the inherent front and rear edge wear (Heel & Toe Wear) of block pattern tires, and the resistance to wear is better than that of block pattern tires.

[0005] However, since the rib tire is mainly used for the front axle, when the direction...
