Embodiment

[0068] manufacturing form figure 2 The basic construction of tires is indicated and their performance is tested.

[0069] And, as a comparison, the same test was also carried out on the following motorcycle tires, namely: Figure 5 The shown main slant groove and auxiliary slant groove are terminated in the eighth region (comparative examples 1, 2, 5), Figure 6 A tire in which the inner ends of the main inclined main groove and the auxiliary inclined groove are located in the third region is shown (Comparative Example 6). Furthermore, the same evaluation was performed on a tire (Comparative Example 1) in which a belt layer of two cut cords was arranged. Among them, the common specifications are as follows.

[0070] Tire size:

[0071] Front wheel: 120 / 70ZR17

[0072] Rear wheel: 190 / 50ZR17

[0073] Rim size:

[0074] Front wheel: MT3.50×17

[0075] Rear wheel: MT6.00×17

[0076] Tread width TW: 120mm

[0077] Tread expansion width TWe: 168mm

[0078] Carcass cord:...

Abstract

The invention discloses a tire for a motorcycle. The tire can have both handling stability and drainage performance at a high level. Main inclined grooves (11) and auxiliary inclined grooves (12) areformed in a tread portion (2) of the tire (1) for the motorcycles. The main inclined grooves (11) include first main inclined grooves (11A) extending from one side (E1) to the other side (E2), and second main inclined grooves (11B) extending from the other side (E2) to one side (E1). The auxiliary inclined grooves (12) include first auxiliary inclined grooves (12A) arranged between the first maininclined grooves (11A), and second auxiliary inclined grooves (12B) arranged between the second main inclined grooves (11B). Moreover, the tread portion (2) is equally divided into ten small tread regions (T1 to T10) from a tire equator (C) to the tread end, and the land ratio (L1 to L10) of each small tread region is 70-90%.

Description

technical field [0001] The present invention relates to a tire for motorcycles capable of achieving both steering stability performance and drainage performance at a high level. Background technique [0002] In recent years, along with the construction of the highway network and the increase in the output of motorcycles, motorcycle tires are strongly required to improve steering stability. In such tires, in order to improve the steering stability performance, it is very important to increase the land ratio of the tread portion and to improve the limit performance of gripping as much as possible. [0003] However, when the land ratio of the tread portion is excessively increased, the area of ​​the grooves provided in the tread portion is reduced, resulting in a problem that drainage performance is reduced. Conventionally, in motorcycle tires, the following Patent Document 1 has been proposed in order to achieve both such antinomial performances. [0004] Patent Document 1: ...
