<p>A pneumatic tire (100) is provided having a carcass with at least one carcass ply, optionally an innerliner (124), a sidewall (106), a bead (108) comprising a bead core (110) and a bead apex (48), and a tread (102) disposed radially outward of the carcass. The sidewall (106) has preferably only a single crescent-shaped rubber insert (42) located between the innerliner (124) and the at least one carcass ply (114, 116). The rubber of the at least one crescent-shaped rubber insert has a hardness (Shore A, 100°C) in a range of 68 to 90, and the maximum thickness of the at least one crescent-shaped rubber insert (42), as measured parallel to the axis of rotation of the tire, is less than 30% of the thickness of the tire sidewall (106) as measured parallel to the axis of rotation of the tire from the axially inner surface of the sidewall (106) to the axially outer surface of the sidewall (106) at the location of the maximum thickness of the at least one rubber insert (42).</p> |
