To prevent air leakage caused by deformation of a tire if the tire comes into contact with stone, fallen tree, etc. when a vehicle travels on unpaved road (including a forestry etc.) and to reduce fall of the tire.SOLUTION: When assuming air leakage caused by deformation of the tire due to the tire 10 coming into contact with stones, fallen trees, etc. in traveling on an unpaved road (including a forestry etc.) and assuming that the tire 10 punctures, a tire 10 deforms. Therefore, a tip part of a bead part 20 attempts to come out of a bead seat 104, but the bead part 20 laps over ribs 106, 108 and thereby reduces the leakage of air in the tire, thus restraining further deformation of the tire 10. In addition, when the bead part 20 attempts to come out of a rim part 101, the bead part bumps into a side wall 112 of a hump 110 and is blocked, so that the bead part 20 stays in the bead seat 104 to reduce fall of the tire 10.SELECTED DRAWING: Figure 1
