Description of the Related Art Conventionally, a tire of a two-wheeled vehicle is intended to reduce the weight of each wheel as a general rule by adopting the same structure for the front and rear wheels. It is possible.). Further, for the purpose of improving the steering stability of a two-wheeled vehicle, improving the tire balance in cornering, improving the elastic recovery of the tire, and the like, a structure in which a steel cord is arranged in the carcass portion is adopted. However, with this steel cord-containing tire, we intend to reduce the weight in the same way as in the past and aim to improve various performances based on this, and in recent years, we have decided to deploy ultra-fine steel cords in a net shape. By adopting and by adopting this, for example, as described above, the weight of the tire is reduced.

The rear tire of the present invention is a rear tire of a two-wheeled vehicle, and the test vehicle of the applicant of the present invention was tested under the following conditions. Experimental vehicle and contents Suzuki Sx200R (off-road type) Maximum speed 110Km / h (normal tire) Maximum output 20PS / 8500rpm Maximum torque 1.7kgm / 7000rpm Tire size (rear) 110 / 80-18.58P Weight 500g The divided plate rounds are fixed to the carcass portion of the tire with an adhesive, and the plate rounds are arranged almost uniformly over the entire tire interior. And it is the result of the running test based on the principle of the flywheel. In the above experimental vehicle, no problems occurred in the turning performance, braking stop distance, etc. due to the increase in the weight of the rear tires. On the other hand,
The following features were revealed. That is, (1) the acceleration force was increased. (2) Improvement of fuel efficiency was achieved.
(3) There was a large reduction in shocks when shifting up. (4) The maximum speed was secured, albeit slightly. The experimental results such as are found.

Includes motocross type, off-road type, on-road type, road racer type, turnip, moped motorcycle, other types, etc. ), A weight 3 is provided on the inner circumference of the carcass 2 of the rear wheel tire 1, and the weight 2 is, as a general rule, provided substantially evenly in the inner surface circumferential direction. . That is, the weight of the entire rear tire 1 is increased in a balanced manner. It is to be noted that it is ideal that the weights 3 are embedded in the entire circumferential direction of the carcass 2 in consideration of the occurrence of puncture and other rear wheel cutting damage, as shown in FIGS. The inner surface of the weight 3 is preferably flush with the inner surface of the carcass 2 in the circumferential direction (indicated by the arrow in FIG. 3). The weight 3 may be mixed as the weight particles 31 into the carcass 2. As an example, as shown in FIG. 5, the weight particles 31 are added to the rubber material 21 that constitutes the carcass 2.
In addition, as shown in FIG. 3, the weight material 31 is mixed in the rubber material 21a recessed in the carcass 2 and, for example, a structure in which the carcass 2 is recessed at eight positions is adopted. .
