Patent ID: 6955203

Claim:
A device for breaking the bead of a tubeless tire installed on a wheel, comprising: a hand grip; a wedge member comprising a proximal end having a substantially rectangular cross-section and attached to said hand grip, opposing working surfaces tapered from said proximal end to a distal edge, and a plurality of runners formed in said working surfaces and extending between said distal and proximal ends, wherein said wedge member further comprises a plurality of alternating parallel runners and grooves extending along each of the working surfaces of said wedge member from the proximal end to the distal edge; said runners for reinforcement of said wedge member and for providing low-friction bearing surfaces, and said grooves for providing a channel-outlets for the free escape of air from the tire; whereby said wedge member may be inserted between a wheel rim and a tubeless tire, and said hand grip pushed towards the wheel to leverage the wedge against the wheel rim and laterally displace the bead of said tire.
