Abstract: A tire includes a tread portion including a tread rubber including a cap tread and an undertread, a pair of bead cores, a carcass layer extended across 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 at break TB_cap (MPa) of the cap tread is in a range 12?TB_cap?35. A relationship between an amount of change between a ground contact area CA80 at 80% of a maximum load capacity and a ground contact area CA120 at 120% of the maximum load capacity and the tire outer diameter OD satisfies 0.0004×OD?{(CA120?CA80)/CA80}?0.0030×OD.

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. The belt layer includes a pair of cross belts formed of a wide cross belt and a narrow cross belt. A distance Tce (mm) from a tread profile to an outer circumferential surface of the wide cross belt in a tire equatorial plane CL has a relationship 0.008?Tce/OD?0.130 with respect to the tire outer diameter OD (mm).

Abstract: In a tire, a tire outer diameter OD is in a range 200 mm?OD?660 mm. A total tire width SW is in a range 100 mm?SW?400 mm. A carcass layer is formed by layering two layers of carcass plies formed by covering organic fiber cords with coating rubbers. The organic fiber cords of the two layers of the carcass plies have cord angles in a range of 80 degrees or more and 100 degrees or less with respect to a tire circumferential direction. A tensile strength Tcs per a width of 50 mm of each of the two layers of the carcass plies (13A, 13B) is in a range 17 N/mm?Tcs/OD?120 N/mm with respect to the tire outer diameter OD.
