Abstract: A wheel for mounting tubeless tires in which the bead of the tire is sealed and clamped on one or both sides of the wheel. The bead is sealed and clamped by a bead locking ring having a peripheral lip on an axially parallel surface of revolution, terminating in an annulus which mates with a similar surface of revolution formed on one or both ends of the wheel having a matching annulus to which the ring is securely bolted. The annulus on the wheel is provided with a plurality of blind threaded inserts for receiving bolts which pass through the ring, securely clamping the bead between a peripheral lip on the wheel and the lip on the bead locking ring. The locking ring is formed so that the mutual surfaces of revolution on the locking ring and the wheel respectively provide lightweight, reinforced stiffening of the locking ring (i.e. in-plane strength), preventing bending and warping when bolted to the wheel.
