Problems solved by technology

[0009] However, in the above-mentioned patent application, simply making the height of the outermost rib lower than that of the adjacent ribs cannot completely prevent abnormal wear of the outermost rib (including the decoupling groove)
[0010] In addition, it can be known that since the outermost rib has a simple structure, there is a problem that the abnormal wear phenomenon occurs rapidly after the tire has been used for a certain period of time.

Embodiment Construction

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] figure 1 Shown is a partial perspective view of the tire of the present invention, figure 2 Shown is a partial enlarged sectional view of the main part of the present invention.

[0017] Such as figure 1 and figure 2 As shown, the pneumatic tire for load bearing of the present invention includes a tread portion 1, a sidewall portion 2 and a bead portion 3, and a decoupling groove 4 is formed on the shoulder portion 10 of the tread portion 1, wherein, in the decoupling A sacrificial rib 5 is formed at the center inside the groove 4 .

[0018] The height h1 of the sacrificial rib 5 is lower than the height h of the rib 12 formed at the outermost end, and the height h1 of the sacrificial rib 5 is 30-90% of the height h of the rib 12 formed at the outermost end.

[0019] In addition, a plurality of grooves 51 at equal intervals...

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...
