Embodiment approach

[0021] Such as Figure 1 to Figure 5 As shown, the present invention discloses a tread pattern structure of a car spare tire. The tread pattern is divided into two central pattern blocks 2 and two shoulder pattern blocks 5 by three main grooves, and each pattern block is cut by an auxiliary groove. In block shape, the three main grooves are the first main groove 11 circumferentially arranged in the center of the tread and the second main groove 12 symmetrically circumferentially arranged on both sides of the first main groove 11; the tread also includes several circumferential grooves. The pattern groove units are distributed on the tread, and each pattern groove unit includes two central auxiliary grooves 4 that are laterally inclined and connected to the first main groove and the second main groove on one side, and the first extended shallow grooves of the two central auxiliary grooves. 8. The second extended shallow groove 7 of the two central auxiliary grooves, and the ext...

Abstract

The invention discloses a car spare tire tread groove structure. A pattern is divided by three main trenches to form two center pattern blocks and two tire tread groove blocks, and the three main grooves comprise a first main groove circumferentially arranged in the center of a tire tread and second main grooves symmetrically circumferentially arranged at two sides of the first main groove; the tire tread also comprises a plurality of tread groove units circumferentially distributed on the tire tread, and each of the tread groove units comprises two tire shoulder auxiliary grooves transversely tilting and arranged symmetrically to the normal of the first main groove and then symmetrically to a line vertical to the normal of the first main groove, two center auxiliary groove first extension shallow grooves, two center auxiliary groove second extension shallow grooves, two tire shoulder auxiliary groove extension shallow grooves and two center auxiliary grooves; and the two center auxiliary grooves have a tilting reverse-Z-shaped shape, and are connected with the first main groove and the second main grooves respectively. The car spare tire tread groove structure can guarantee the basic wetland performance of a tire, reinforces the whole rigidity of the tire tread, improves the sideslip resistance of the tire tread, and ensures the control stability during turning.

Description

technical field [0001] The invention relates to a tire tread pattern structure, in particular to a car spare tire tread pattern structure. Background technique [0002] Spare tires, as a spare product, are used less frequently and are only used for a short time in emergency situations. Their performance requirements are different from those of floor-standing tires, and they are not as wear-resistant, quiet, and high-speed as floor-standing tires. Generally harsh. It mainly focuses on the handling stability of the tires when driving, especially the turning characteristics when the front and rear wheels are matched and the anti-skid performance when cornering. In addition, considering the safety of use in rainy days, there are also more requirements for wetland performance. In order to take into account the maneuverability of dry and wetlands, the land-to-sea ratio must be limited within a certain reasonable range. [0003] In addition, because of its spare purpose, in order...
