Small Engines (Lawn Mowers, etc.): wheel removal

Question
I have a Snapper Pro 36 with a bad valve stem in the wheel.  How do I remove the wheel so that I can take it to be replaced.?

Answer
In theory you just remove the C clip holding the rim (wheel) to the axle and slide off the tire assembly.

Have you removed the C clip and sprayed penetrating oil on the axle and rim?  Rust will cause the wheel to freeze to the axle shaft.

Are there 2 holes inside the rim?
