Description

1255240 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a "bicycle tire having a combined tread", and more particularly to a combined tread design for bicycle tires, which utilizes different hardnesses. The tread layer is composed of tire structures that can improve the structural strength, longevity and grip. Give it to you. The leisure group and the floor planners read the fun of the construction of the tires and the Lohas step in the face of the ride and the rider’s leisure and the rider’s leisure It is this shoulder wheel used by the people to make the base tires available to the public. Provided by the side, the civilian car can be promoted in one line, and the line is to be pushed, the automatic main layer is pushed down, the force of the surface is pushed, and the surface of the road is replaced by the tires of the tires. The car in the middle of the road is busy in the week, welcoming the pattern, driving, and arranging the skills of the day, and the layering of the layer is the first step. , solved the shoulder to ί 升 P, tire, [content] (the technical problem to be solved), but the inventor found that the aforementioned bicycle tire structure, when the vehicle is driving on a straight road, the tire tread layer Should have a hard tread, ^ can increase the guiding force of the tire, and its shoulder should have a soft tread, can be used to increase the grip, but the used tire structure is the same hardness of the rubber integrated molding Tread, can not provide the different hardness required for each tread layer, it is easy to cause uneven wear of the tire, and the inner layer of the tire is in the condition of no protection, and the valley easily causes the insertion of the puncture to cause the internal peripheral structure. damage
