A radial tire having a carcass ply (17) with an inside-to-outside turn-up portion (19) around each bead (13). In each bead portion (11) there is included a reinforcing ply 22 having portions (22A,22B) on each axial side of the bead (13). The axially outer portion (22A) adjacent each turn-up portion (19), and optionally the turn-up itself, extends radially outwardly of the bead (13), and the axially inner portion (22B) extends radially outwardly to terminate at a point (S) located on a line (Q-Q) which is substantially perpendicular to the carcass ply (17) and passing through the radially outermost end (R) of axially outer portion (22A), or the radially outermost end (U) of the carcass ply turn-up (19). |
