Tire with concave sidewalls

A tire comprising:

• a convex circumferential tread having a convex cross-section, wherein the convex cross-section is defined by a radius that is less than a maximum radius of the tire;
• a first concave sidewall extending from the convex circumferential tread at a first hinge,
• wherein the first concave sidewall includes a first concave exterior surface and a first concave interior surface, the first concave exterior surface and the first concave interior surface being concave from an exterior perspective of the tire, and
• wherein the first concave exterior surface is defined by a single radius that is greater than a maximum radius of the convex cross-section of the circumferential tread;
• and
• a second concave sidewall extending from the convex circumferential tread at a second hinge opposite the first hinge,
• wherein the second concave sidewall includes a second concave exterior surface and a second concave interior surface, the second concave exterior surface and the second concave interior surface being concave from the exterior perspective of the tire,
• wherein the second concave exterior surface is defined by a single radius that is greater than the maximum radius of the convex cross-section of the circumferential tread,
• wherein a line tangent to an interior surface of the convex circumferential tread at the first hinge, and a line tangent to an interior surface of the first concave sidewall at the first hinge form a first interior angle greater than 90-degrees when the tire is not placed under radial compression, and
• wherein a line tangent to the interior surface of the convex circumferential tread at the second hinge, and a line tangent to an interior surface of the second concave sidewall at the second hinge form a second interior angle greater than 90-degrees when the tire is not placed under radial compression.
