Abstract
In a tire, a point (Au) on a side profile at the same position in a radial direction as an end portion of an innermost layer of a belt layer is defined in a cross-sectional view in a meridian direction. A distance (Hu) from a maximum width position (Ac) to the point (Au) in the radial direction is defined. A point (Au′) on the side profile at the radial position of 70% of the distance (Hu) from the maximum width position is defined. A point (An) on the side profile at the radial position of 35% of the distance (Hu) from the maximum width position is defined. A radius of curvature (RP) (mm) of an arc passing through the maximum width position, the point (Au′), and the point (An) with respect to a cross-sectional height (SH) (mm) is in a range 0.20≤RP/SH≤1.80.
Claims12
A tire, comprising:
- a pair of bead cores:
- a carcass layer extending between the bead cores;
- and
- a belt layer disposed on an outer side of the carcass layer in a radial direction:
- a tire outer diameter OD (mm) being in a range 200≤OD≤660,
- a total tire width SW (mm) being in a range 100≤SW≤400,
- in a cross-sectional view in a tire meridian direction,
- a point Au on a side profile at a position in a tire radial direction identical to an end portion of an innermost layer of the belt layer being defined, a distance Hu from a tire maximum width position Ac to the point Au in the tire radial direction being defined, a point Au′ on the side profile at a radial position of 70% of the distance Hu from the tire maximum width position Ac being defined, a point An on the side profile at a radial position of 35% of the distance Hu from the tire maximum width position Ac being defined, and
- a radius of curvature RP (mm) of an arc passing through the tire maximum width position Ac, the point Au′, and the point An when the tire is mounted on a specified rim, inflated to a specified internal pressure, and in an unloaded state with respect to a tire cross-sectional height SH (mm) being in a range 0.20≤RP/SH≤1.80.
