The left tire on my Murray Model 624808x4C snow thrower has gone flat. I want to remove the wheel and tire but there is a small metal flange at the end of the shaft that makes this impossible. What is the best way to remove this tire and get it repaired?

Can't seem to look up the diagram from Ariens® >> Customer Service >> Parts Radar (http://www.ariens.com/customerservice/partsradar.aspx)

And searspartsdirect.

Split pins are sometimes used to attach wheels. The attachment is then on the inside of the rim and it has to be driven out.
