If you are in need of either front or rear 26" mountain bike tire/tube/rim assemblies...I have six (4 front and 2 rear). Both quick release and standard hubs available. The rear assemblies have a 6 or 5 sprocket. Also worth mentioning, one of the front and rear assemblies is tubeless (solid foam), so no air required. Each assembly is $15, and have very good tread (see photos).
