Abstract:
A pneumatic vehicle tire comprises a carcass (11) extending between two bead cores (15). A belt structure (18) is provided between the carcass (11) and a tread strip (19) which is connected with a pair of sidewalls (20). A runflat reinforcement (17) is arranged at the inner side of each sidewall (20). A reinforcer (13) is arranged within each bead portion of the tire. A bead filler (14) extends from the bead ring (15) along the reinforcer (13). To improve the runflat performance, handling and comfort properties of such a runflat tire the reinforcer (13) is arranged at the inner side of the bead filler (14). The reinforcer (13) comprises metal cords. The bead filler (14) which extends beyond an end (13a) of the reinforcer (13) is made of a soft rubber compound with an IHRD hardness lower than (80), e.g. between (75) and (79).
