Embodiment

[0068] manufacturing form figure 2 The basic structure shown and the tires with the main inclined grooves and auxiliary inclined grooves shown in Table 1, and their performances were 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.

Abstract

The invention discloses a motorcycle tire which has both an excellent control stability performance and a drainage performance. A motorcycle tire (1) is provided with main oblique grooves (11) and auxiliary oblique grooves (12) on a tread portion (1). The main oblique grooves (11) comprise first main oblique grooves (11A) extending from one side (E1) to the other side (E2) and second main oblique grooves (11B) extending from the other side (E2) to one side (E1). The auxiliary oblique grooves (12) comprise first auxiliary oblique grooves (12A) configured between the first main oblique grooves (11A) and second auxiliary oblique grooves (12) configured between the second main oblique grooves (11B). And moreover, the tread portion (2) is grooved so that ten narrow annular zones thereof each have a land ratio (L1-L10) of 70 to 90 %, wherein the ten narrow annular zones are defined by equally dividing tread portion (2) from a tire equator (C) to a tread end.

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: ...
