くてはならないものである。2. Description of the Related Art A typical tire-rim assembly is a bead seat of a rim that includes an annular bead portion formed at radially inner ends of a pair of sidewalls extending radially from both ends of an annular tread portion of the tire. By fitting, by inflating the tire by inflating the tire and expanding the tire, the bead base of the bead portion, the bead toe and the bead heel are formed in close contact with the bead seat portion of the rim, and in particular, in a tubeless tire, In order to maintain the internal pressure of the tire, the adhesion between the bead portion and the bead seat portion of the rim must be increased.

傷につながる恐れがあった。However, in the conventional tire-rim assembly, the contact surface of the bead portion and the contact surface of the bead seat portion are formed smoothly, respectively.
Since it is only held by the contact friction due to the internal pressure of the tire, when the vehicle performs sudden acceleration or sudden deceleration,
The difference between the actual vehicle speed and the tire rotation speed increases,
The force exerted on the tire resulting from this speed difference (especially a large value during sudden deceleration) acts on the contact surface between the tire and the rim to generate a shear stress between the bead portion and the bead seat portion. Becomes larger than the coupling force between the bead portion and the bead seat portion, a deviation (rim deviation) occurs between the bead portion and the bead seat portion, and this rim deviation may cause a decrease in braking performance. Further, in the tube type tire, the air valve protruding from the tube may collide with the peripheral edge of the valve hole formed in the rim, resulting in damage.

である。Since the present invention is constructed as described above, it has the following effects. Since the bead portion of the tire and the bead seat portion of the rim are provided with irregularities that are engaged with each other at equal intervals, the actual vehicle speed of the vehicle and the rotation speed of the tire are significantly reduced when the vehicle performs sudden acceleration or sudden deceleration. When the difference becomes large and a displacement stress occurs between the bead portion and the bead seat portion, it is possible to prevent the rim displacement from occurring. Further, by forming the central axis of the intermeshing provided on the bead portion of the tire and the bead seat portion of the rim at a predetermined angle with respect to the traveling direction of the tire, between the bead portion and the bead seat portion. To further increase the coupling force against the generated shear stress, especially during sudden deceleration, when the rotation speed of the tire becomes faster than the rotation speed of the wheel, the bead part will be guided in the tire inward direction, and the coupling against the shear stress will be increased. The force is further increased, and the fitting between the tire and the rim is facilitated.
