Abstract:
A pneumatic tire comprisinga tread portion, a pair of sidewall portions, a pair of bead portions, a carcass extending between the bead portions, a wheelrim protector provided in at least one of said sidewall portions, said wheelrim protector protruding from a circular arc C1 so as to overhang a flange of a wheelrim when the tire is mounted thereon and to protrude axially outwardly from an axially outer end of the flange, wherein said circular arc C1 is defined as having the center on an axial line N passing maximum section width points of the carcass, and passing through a point M on the outer surface of the tire at the same radial height as the maximum section width points of the carcass, and circumscribing the flange of the wheelrim, said wheelrim protector having a vertex which defines a maximum thickness Tmax of 3 to 20 mm, the thickness being measured from the surface to said circular arc in the normal direction thereto, the difference (Hfâˆ’Hr) of the radial height Hf of the vertex from the radial height Hr of the rim flange being not less than 0.5 mm and not more than 0.45 times the radial height Hw of the maximum width point of the carcass, each radial height measured from a bead base line BL, and said wheelrim protector provided with at least one circumferential slit around the axis of the tire.
