Pneumatic tire
Provided is a pneumatic tire. In a tire meridian cross-sectional view of an unloaded state in which regular internal pressure is applied, a tire profile between two ground contact edges is constituted by two tire outer side profiles each having a dimension along the tire profile of 20% or more and 35% or less with respect to a dimension between the ground contact edges along the tire profile, and a tire inner side profile other than the two tire outer side profiles, the tire outer side profiles being constituted by at least four curved lines having different shapes.
1. A pneumatic tire comprising, in a tire meridian cross-sectional view of an unloaded state in which regular internal pressure is applied, a tire profile between two ground contact edges consisting of two tire outer side profiles each having a dimension along the tire profile of 20% or more and 35% or less with respect to a dimension between the ground contact edges along the tire profile, and a tire inner side profile other than the two tire outer side profiles, the tire outer side profiles comprising at least four curved lines having different shapes and the tire inner side profile consisting of one curve having a same curvature.
2. The pneumatic tire according to claim 1 , wherein a radius of curvature of a curved line on the innermost side in a tire width direction among the curved lines comprising the tire outer side profiles is 0.40 times or more and 0.60 times or less of a radius of the one curve of the tire inner side profile.
3. The pneumatic tire according to claim 2 , wherein a radius of curvature of a second curved line from an inner side in the tire width direction among the curved lines comprising the tire outer side profiles is 0.70 times or more and 0.90 times or less of a radius of curvature of a curved line on an innermost side in the tire width direction of the curved lines comprising the tire outer side profiles.
4. The pneumatic tire according to claim 3 , wherein a dimension along the tire profile of each curved line comprising the tire outer side profiles is 2.0% or more and 5.0% or less of a tread development width.
5. The pneumatic tire according to claim 1 , wherein a radius of curvature of a second curved line from an inner side in the tire width direction among the curved lines comprising the tire outer side profiles is 0.70 times or more and 0.90 times or less of a radius of curvature of a curved line on an innermost side in the tire width direction of the curved lines comprising the tire outer side profiles.
6. The pneumatic tire according to claim 1 , wherein a dimension along the tire profile of each curved line comprising the tire outer side profiles is 2.0% or more and 5.0% or less of a tread development width.
