Heavy Duty Tyre Abstract A pneumatic tyre (10) includes a bead portion having an apex (24) which extends 5 radially outward of a bead core (16), a first turn-up pad (30) located adjacent a chafer (28), and a second turn-up pad (40) located adjacent the first turn-up pad (30). The first turn-up pad (30) has a G' less than the G' of the second turn-up pad (40). Alternatively, the first turn-up pad (50) may be located adjacent to a rim flange and the second turn-up pad (60) may be located axially inward of the first turn-up pad (50). The second turn-up pad (60) is 1o preferably thicker and longer than the first turn-up pad (50). -20 40, FIG-1I |
