摘要: A pneumatic vehicle tire includes a carcass extending between two bead cores. A belt structure is provided between the carcass and a tread strip which is connected with a pair of sidewalls. A runflat reinforcement is arranged at the inner side of each sidewall. A reinforcer is arranged within each bead portion of the tire. A bead filler extends from the bead ring along the reinforcer. To improve the runflat performance, handling and comfort properties of such a runflat tire, the reinforcer is arranged at the inner side of the bead filler. The reinforcer includes metal cords. The bead filler which extends beyond an end of the reinforcer, is made of a soft rubber compound with an IHRD harness lower than 80.
