Abstract: A high aspect ratio agricultural pneumatic tire has a carcass including a pair of bead portions each having a bead core and two pair of first and second carcass plies of synthetic cords oriented radially and wrapped from the inside of each bead core around to an axially outer turnup end. The first pair of plies is radially inward and adjacent the second pair of plies between the bead cores and having the turnup ends T1, T1? wrapped about the bead cores and the turnup ends T2, T2? of the second pair of plies. The turnup end of the first pair of plies extends outwardly and radially along the bead filler wherein T1, T1? are located between 60% and 80% of the radial location Y of maximum section width (SW) of the tire and T2, T2? are located between 30% and 50% of Y.
