Problems solved by technology

However, these measures may lead to a reduction in the tire's ability to absorb impacts and gaps on the road surface, so that the stiffness of the blocks on the tread surface must be lower than that of bias cord tires, which also Reduced grip performance
Therefore, for uneven road radial tires, it is extremely difficult to secure the sidewall stiffness and improve the cornering characteristics without reducing the tire's ability to absorb impacts and the like on the road surface.

Embodiment 1

[0063] Example 1 is a motorcycle bias cord tire having the tread pattern shown in FIG. 1 and the parameters shown in Table 1. For convenience of comparison, a motorcycle bias cord tire having a tread pattern as shown in FIG. 8 and parameters as shown in Table 1 (Comparative Example 1) was also prepared. Both Example 1 and Comparative Example 1 had a carcass consisting of two bias plies formed of rubberized nylon cords extending at an angle of ±30 degrees with respect to the radial direction.

Embodiment 2

[0065] Example 2 is a motorcycle radial tire having a tread pattern as shown in FIG. 1 and parameters as shown in Table 2. For convenience of comparison, a motorcycle radial tire having a tread pattern as shown in FIG. 8 and parameters as shown in Table 2 (Comparative Example 2) was also prepared. Both Example 2 and Comparative Example 2 had two belt layers made of rubberized aramid cords and one belt reinforcement layer made of rubberized nylon cords.

Abstract

The present invention is to provide a motorcycle tire capable of remarkably improving a traction characteristic and an anti-sideslip characteristic for cornering without deteriorating the mud expulsion characteristic especially on a dirt road. <??>A motorcycle tire has a plurality of main blocks 2 scattered on a tread 1. Sub blocks 3 are provided between the main blocks 2. The sub block 3 is made of rubber and has block height H2 lower than that the height H1 of the main block 2. A part of the rubber constituting a top portion 9 of the sub block 3 has been removed to reduce the area of a upper face 5 of the sub block 3.

Description

technical field [0001] The present invention relates to a motorcycle tire, in particular to a motorcycle tire on uneven roads, such as off-road racing motorcycle tires suitable for use on uneven roads such as muddy roads. Background technique [0002] Motorcycle tires used on uneven road surfaces such as muddy roads generally have a tread pattern provided with several lugs. Such motorcycle tires are particularly required to have a higher level of turning characteristics when running on a muddy road because, among various necessary characteristics, turning characteristics and traction and braking characteristics are considerably important. In particular, with sports tires used in competitions such as motocross, the motorcycle turns at such a high speed that the lateral grip of the tire becomes an extremely important factor in determining how good the cornering characteristics are. [0003] However, conventional motorcycle tires for use in muddy road conditions have a basic p...
