Embodiment Construction

[0018] refer to figure 1 and 2 A pneumatic tire 10 according to the present invention includes a tread strip 19 and a pair of sidewalls 20 connected to the tread strip 19 . The carcass 11 is associated with two bead cores 15 arranged in the bead portion of the tire 10 . as available from figure 2 As seen, the carcass 11 is rolled up around the bead rings 15 . The carcass 11 thus comprises two parts, namely a part 11 a in the bead part and a part 11 b in the area of ​​the sidewall 20 . In the bead portion of the tire 10 , the inner carcass portion 11 a and the outer carcass portion 11 b are separated by a bead core 15 and a bead filler 14 . The carcass portions 11 a and 11 b are joined together at a ply joint 12 . In the region of the side walls 20, the carcass parts 11a and 11b are directly connected to each other. The outer carcass portion 11 b extends to a belt structure 18 arranged between the carcass 11 and the tread strip 19 . Typically, the belt structure 18 comp...

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).

Description

technical field [0001] The present invention relates to a runflat pneumatic vehicle tire comprising a carcass in conjunction with two bead cores in respective bead portions of the tire, a belt structure disposed between the carcass and the tread strip, a pair of sidewalls located at an intermediate portion of the tire disposed between each bead portion and the tread strip, a pair of sidewalls disposed on each sidewall A runflat reinforcement at the inner side, a reinforcement arranged in each bead portion of the tire and a bead filler extending from each bead core along the respective reinforcement are associated. [0002] Such run-flat tires feature a stiffer interior that is capable of temporarily carrying the weight of the vehicle even after the tire has lost all air pressure. To provide self-supporting capability, runflat reinforcements are provided at the inner side of each side wall. Background technique [0003] EP-B-1 013 482 discloses a vehicle tire comprising a c...
