2. Description of the Related Art Generally, a flat pneumatic tire has a low section height. For this reason, when a flat pneumatic tire is assembled on a rim, the rim flange is in a state of protruding from the maximum tire width, and there is a drawback that the rim flange is liable to come into contact with a curbstone or the like during traveling.

Therefore, in order to protect the rim flange,
A flat pneumatic tire has been proposed in which a rubber volume portion that protrudes in the tire width direction beyond the rim flange in a state where the rim is assembled is integrally formed on the side portion.

However, when the flat pneumatic tire having the above-described conventional rubber volume portion is mounted on the rim having the maximum rim width within the allowable range of the tire size, the rubber is The amount of protrusion of the volume portion is very small, or the rim flange protrudes more than the rubber volume portion, so the protection effect of the rim flange cannot be sufficiently obtained. As described above, the conventional flat pneumatic tire having the rubber volume portion has a problem that it cannot cope with a change in the rim width. Also,
If the rubber volume is made thicker in order to obtain a sufficient protection effect for the rim flange, the fitting pressure during rim assembly rises,
The rim assembly performance will be reduced.

Further, the rim protector according to the present invention is
The pneumatic tire assembled on the rim is composed of an annular rubber protective material which is retrofitted to a side area from a contact portion with a rim flange to a tire maximum width portion and protrudes in the tire width direction from the rim flange. It is what In the present invention, the annular rubber protective material is retrofitted to the side region from the contact portion of the rim-assembled pneumatic tire with the rim flange to the tire maximum width portion, that is, the side portion of the pneumatic tire. Therefore, since it is not necessary to use a pneumatic tire in which a rubber volume portion is integrally formed on the side portion, the fitting pressure at the time of assembling the rim does not increase and the rim assembling property is not impaired. Further, the rubber protective material can be appropriately selected according to the relationship between the tire size and the rim width, and therefore can be made to protrude in the tire width direction from the rim flange when retrofitted. Therefore, regardless of the relationship between the tire size and the rim width, a sufficient protection effect for the rim flange can be obtained. Further, the rubber protection material has an advantage that it can be easily replaced when it is damaged.

As the material of the rubber protective material, it is preferable to use a material softer than the side compound of the pneumatic tire in order to sufficiently obtain the protective effect of the rim flange. The cross-sectional shape of the rubber protective material is not particularly limited, and may be triangular, trapezoidal, semicircular, semielliptic, or the like. The rubber protective material according to the present invention is particularly preferably applied to a flat pneumatic tire having a flatness of 60% or less. In this case, it is possible to prevent the rim flange from coming into contact with the curbstone or the like, and it is possible to reliably protect the rim flange.
