An arrangement relating to pneumatic tubeless tires which are fitted with a tire bead (12) in sealing abutment with a rim seat (13) inwardly from a rim edge (14) on each side of an undivided rim (11). The tire is provided with an internal seal (16) which is made of rubber or some like elastic material and which extends inwardly from the tire bead (12) along the rim seat (13). The outer part of the internal lip seal (16) that lies proximal to the rim edge (14) is fastened to the tire bead (12) at a distance from its end. The inner part of the internal seal (16) that lies proximal to the centre of the rim (11) has a circumference that is slightly smaller than the circumference of the rim (11) at this location. The seal (16) is adapted to seal at least around the region in which the tire bead (12) is in abutment with the rim seat (13) through the influence of the pneumatic pressure in the tire (10). |
