A method of making a tire includes providing a first body ply having a first width and laying a second body ply above the first body ply. The second body ply has a second width less than the first width. The method also includes laying a third body ply above the second body ply. The third body ply has a third width greater than the first width. The method further includes laying a first bead at a first location above the third body ply, laying a second bead at a second location above the third body ply, laying a first stabilizer ply insert at a third location above the third body ply, and laying a second stabilizer ply insert at a fourth location above the third body ply. The third location is between the first location and the second location, and the fourth location is between the third location and the second location.

Method of making a tire with multiple body plies

A tire includes a pair of beads and a plurality of body plies extending between the pair of beads, including at least a first body ply and a second body ply. The first body ply wraps around each of the pair of beads, and has a first pair of turn up portions having a first height. The second body ply wraps around each of the pair of beads, and has a second pair of turn up portions having a second height greater than the first height. Each of the second pair of turn up portions is axially inside each of the first turn up portions. The tire also includes a circumferential belt disposed radially above the plurality of body plies, a circumferential tread disposed radially above the circumferential belt, and a pair of sidewalls extending between the pair of beads and the circumferential tread. The tire also has a pair of stabilizer ply inserts, including a first stabilizer ply insert and a second stabilizer ply insert.
