A bead seating system which comprises a wheel and tire support having a small diameter central hub, a plurality of widely spaced radial clamp carrying support arms, a single, elongated air nozzle located below and in proximity to the support and a noise reduction housing enclosing the nozzle. The orifice of the nozzle is elongate in the horizontal direction and directs a flat, trapezoidal stream of air through an opening in the noise reduction housing and the space between two of the radial support arms into the area between the bead of the tire and the rim of a wheel resting on the support. The nozzle is angularly oriented relative to the horizontal so that for all rim sizes the air stream is directed either into the space between the rim and the bead or in a direction nearly tangential to the outer wall of the tire. Accordingly, the air flows along the side wall of the tire in a laminar manner into the tire.
