Abstract
A tire includes bead cores, a carcass layer extended across the bead cores, a belt layer on a radially outer side of the carcass layer, and a tread portion. The tire outer diameter OD (mm) satisfies 200≤OD≤660. The total tire width SW (mm) satisfies 100≤SW≤400. A groove area ratio Aa (%) of the tread portion satisfies 0.008≤Aa/OD≤0.150. When a region of 48×(OD/SW){circumflex over ( )}(1/5) (%) from a maximum ground contact width end portion on a tire inner side when the tire is mounted on a vehicle is defined as a tire inner region of the tread portion, a groove area ratio Ai (%) of the tire inner region and a groove area ratio Ao (%) of a tire outer region as a region other than the tire inner region have a relationship Ai>Ao.
