Problems solved by technology

[0003] However, after the tire 100 has been used for a long time, the outer surface 222 of its block 22 will gradually wear away, presenting an inwardly concave shape (see figure 2 ), when the outer surface 222 of the tire block 22 is sunken, the contact area between the outer surface 222 of the tire block 22 and the ground G becomes smaller, so that the grip of the tire 100 becomes worse
In addition, when the worn tire 100 rolls on the ground with water, the concave part of the outer surface 222 will confine the water therein, and the water cannot be smoothly discharged into the groove 24, causing the tire 100 to slip easily.
Therefore, the design of the commonly used tire 100 is still not perfect and needs to be improved

Embodiment Construction

[0035] In order to illustrate the present invention more clearly, a preferred embodiment is now given and described in detail with accompanying drawings as follows. See Figure 3 to Figure 4 As shown, it is a partial schematic diagram of a tire 200 according to the first preferred embodiment of the present invention. The tire 200 includes a carcass part 30 and a tread part 40 combined on the outside of the carcass part 30. The focus of the present invention lies in the Structure of the tread portion 40 .

[0036] The tread portion 40 includes a plurality of tire blocks arranged along the circumference of the tire 200 and at least two tire grooves arranged along the circumference of the tire 200, these tire blocks are located between the two tire grooves, and these tire blocks form at least one tire ring piece. More specifically, the number of the at least two grooves is at least four, including two first grooves 42 and two second grooves 44; the tread portion 40 includes a c...

Abstract

The invention relates to a tire, which comprises several tire blocks. Each tire block has an external surface with outward projection and two sidewalls, an extension line is defined at a surface of astraight segment of each sidewall, each extension line comprises a first boundary point on each straight segment, and a first transverse reference line is formed by two first junction point lines; a second transverse reference line is defined at the external surface, two second boundary points are formed by two ends of the second transverse reference line and the external surface, and the length of the second transverse reference line is 0.85 times of the length of the first transverse reference line. The distance between the center of the second transverse reference line along a vertical direction and the external surface is 0.2-0.8 mm. Thereby, even wearing of the external surface of the tire blocks, good water drainage and road holding with ground can be kept.

Description

technical field [0001] The present invention relates to tires, in particular to a tire with good drainage performance. Background technique [0002] Such as figure 1 Shown is a part of a commonly used tire 100, including a carcass portion 10 and a tread portion 20 coupled to the outside of the carcass portion 10. The tread portion 20 has a plurality of tire blocks 22 along the tire. 100 circles are arranged to form multiple circles of side-by-side tire blocks 22 , and two tire grooves 24 are formed on both sides of each circle of tire blocks 22 . Each block 22 has an outer surface 222 for contacting the ground, and the outer surface 222 is straight in the transverse direction (or width direction) of the tire 100 . When the tire 100 rolls on the ground, the outer surface 222 will stick to the ground; when the tire 100 rolls on the ground with water, the outer surface 222 of the block 22 will squeeze the water on the ground to the tire groove 24, thereby maintaining a certa...
