PROBLEM TO BE SOLVED: To provide a tire structure allowing a driver to recognize that a tire air pressure is decreased.SOLUTION: This temporary tire is characterized in that a protrusion 23 extending to a tire radial direction outer side having a length grounding on a flat road surface when a tire air pressure is decreased below a normal tire air pressure during vehicle traveling is provided in a sidewall 16 at the outside of a tire maximum width position 21 in the tire radial direction. One to six protrusions are provided in a tire circumferential direction. A distance L between a distal end of the protrusion in the radial direction outer side and the flat road surface is 2 to 20 mm at the normal air pressure during vehicle traveling. The distances between the distal ends of the plurality of protrusions in the tire radial direction outer side and the flat road surface are different. The protrusion is detachable from the tire. The shape of the protrusion is concave or convex in a region where the protrusion is coupled to the sidewall, and the shape of the sidewall to which the protrusion is coupled is the shape for engagement corresponding to the shape of the protrusion. |
