A tire having a circumferential tread, at least one belt, an inner liner, a pair of sidewalls, at least one carcass ply, and a pair of bead portions. The pair of bead portions each further includes a bead core, a bead filler having an upper end, a chaffer, and a gum strip. The chaffer extends axially outward from the inner liner towards the sidewall and curves radially upward along an axially outer portion of the bead core. The sidewall gum strip extends radially upward from a curved portion of the chaffer, wherein the sidewall gumstrip is located axially between the at least one carcass ply turn-up end and a sidewall.
