Abstract
The tire comprises a pair of bead regions having an annular reinforcing structure and at least one carcass reinforcement which is anchored in the pair of bead regions. A protector portion is positioned axially outward and radially inward from the annular reinforcing structure. The protector portion includes a protector surface intended to come into contact with a rim flange and/or a rim sheet of a wheel rim and is provided with at least 2 recessed portions recessed from the protector surface toward an interior of the tire with a depth D. The at least 2 recessed portions have a minimum distance T between one another, and a Young's modulus E of a rubber composition constituting the protector portion is in a range from 1.5 to 6.0 MPa.
