Abstract
A tire includes 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) is in a range 200≤OD≤660. A total tire width SW (mm) is in a range 100≤SW≤400. A strength Tcs (N/50 mm) per a width of 50 mm of a carcass ply constituting the carcass layer is in a range 17≤Tcs/OD≤120 with respect to the tire outer diameter OD (mm).
Claims19
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;
- and
- a strength Tcs (N/50 mm) per a width of 50 mm of a carcass ply constituting the carcass layer being in a range 17≤Tcs/OD≤120 with respect to the tire outer diameter OD (mm);
- wherein
- in a cross-sectional view in a tire meridian direction, a tire maximum width position Ac, a point Al on a side profile of the tire at a same position as an end portion on an outer side in a radial direction of the bead core in a tire radial direction, a distance Hl radially inward from the tire maximum width position Ac to the point Al in the tire radial direction, and a point Al′ on the side profile at a radial position of 70% of the distance Hl radially inward from the tire maximum width position Ac are defined, and
- a distance ΔBl′ (mm) from a point Bc to a point Bl′ in a tire width direction is in a range 1.80≤ΔBl/ΔAl′≤11.0 with respect to a distance ΔAl′ (mm) from the tire maximum width position Ac to the point Al′ in the tire width direction, the point Bc being a point on the body portion of the carcass layer at a same position as the tire maximum width position Ac in the tire radial direction and the point Bl′ being a point on the body portion of the carcass layer at a radial position of 70% of the distance Hu radially inward from the tire maximum width position Ac.
