I have a Dixon ZTR 4515. The front right tire has a slow leak.
I sprayed it with soapy water, including the rims and valve stem, but
can't find the leak.

So I bought a new tire, and I'm wondering what the technique is for
replacing it. I've never worked with tubeless tires. Do I just
deflate it and pry it off with a screwdriver? I don't want to scratch
or gouge the rim so that it can't seal.
