A vehicle tire has a radial carcass and a reinforced crown and the tire beads each comprise at least one beadwire surmounted by a filler strip whose cross-section is broadly tapered towards the side-wall and which is made of a rubbery mixture reinforced with short fibres. According to the invention, the fibres reinforcing the filler strip are, at least in part, orientated in the radial direction of the tire so that the mixture used for the strip has a ratio of anisotropy at least equal to 2:1. The filler strip may rise up the side wall to a height of between 0.2 and 0.5 times the cross-sectional height of the tire.
