Abstract
In a tire, when defining a point A1 on a side profile at the same position in a radial direction as an end portion on an outer side in the radial direction of bead cores, defining a distance H1 from a maximum width position to the point A1 in the radial direction, defining a point A1′ on the side profile at a radial position of 70% of the distance H1, and defining a point Am on the side profile at a radial position of 35% of the distance H1, a radius of curvature RO (mm) of an arc passing through the maximum width position, the point A1′, and the point Am when the tire is mounted on a specified rim, inflated to a specified internal pressure, and in an unloaded state is in a range 0.20≤RO/SH≤1.20 with respect to a cross-sectional height SH (mm).
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,
- the tire having a tire outer diameter OD (mm) in a range 200≤OD≤660 and a total tire width SW (mm) in a range 100≤SW≤400,
- a point A1 being defined on a side profile at a same position in a tire radial direction as an end portion on an outer side in the radial direction of the bead cores, a distance H1 being defined from a tire maximum width position Ac to the point A1 in the tire radial direction, a point A1′ being defined on the side profile at a radial position of 70% of the distance H1 from the tire maximum width position Ac, and a point Am being defined on the side profile at a radial position of 35% of the distance H1 from the tire maximum width position Ac, and
- a radius of curvature RO (mm) of an arc passing through the tire maximum width position Ac, the point A1′, and the point Am when the tire is mounted on a specified rim, inflated to a specified internal pressure, and in an unloaded state being in a range 0.20≤RO/SH≤1.20 with respect to a tire cross-sectional height SH (mm).
