Description

Technical Field

[0001] The invention relates to the technical field of tire patterns, in particular to a stone-proof clamping guide tugboat tire. Background Art

[0002] The tire tread pattern is also called the tread pattern. It is molded or engraved on the outer tread, and its main function is to improve the driving performance of the tire while also enhancing its appearance. The main types are: road patterns suitable for driving on paved roads, also known as ordinary patterns; off-road patterns suitable for driving under unpaved conditions, also known as off-road tread patterns, and their pattern block area accounts for a large proportion of the total crown area; the middle part of the tread driving surface is a road pattern, and the two sides are off-road patterns, which is called a mixed pattern, also known as a general pattern or a universal pattern, and its pattern contact area accounts for about 65% of the total driving surface area; the pattern with driving direction requirements is called a directional pattern, and its pattern is in the shape of a herringbone or a diagonal strip, suitable for Used in construction machinery and agricultural tractor tires, it can provide good traction and self-cleaning properties. When installing tires with this pattern, the apex of the herringbone or oblique strips must be consistent with the direction of travel, and the direction of travel must be marked with an arrow on the sidewall. If mud is used in the opposite direction, the grooves will be filled and traction will be lost. The snow and mud pattern suitable for driving on muddy and icy roads is also called winter tread pattern. This is a block pattern with sharp edges. This pattern has good anti-slip properties and can ensure the safe driving of the tire on icy and muddy roads.
