Looks like a tube type? Maybe just filling with air? If it is a tube and has a hole...you can just google replacing a tire tube.

If not, just lift the mower, take a rope or something and make a tourniquet around the center of the tire, that should flex the sidewalls out enough that they will seal and pop back on when you put air pressure to the valve. You need a good air flow..those little cheapy cig lighter compressors won't cut it.

Sometimes a really good compressor will take care of this for you - it's all about having enough air flow to push the sidewalls out to the rim rather than the air sneaking past.

The tourniquet is a standard method I've used successfully.

compressor

My FIL has an awesome tire shop grade compressor, but I just need to get the wheel over there somehow. How do I take this kind of wheel off? It has some type of curved linch pin.

Cotter pin. Might be tubeless; if so you can do the tourniquet or remove the stem from the rim and install a tube.

To remove the cotter pin you will need to straighten out the end or ends which have been bent over. Then the pin can be pushed or pulled out from the hole in the axle. You'll need a pair of pliers, maybe a hammer and small chisel.

Don't forget to inspect the insides carefully for a nail or the like.

If it's tubeless, and it looks to have that sort of valve stem, remove the valve core before " seating " the tire on the rim with a decent airline, and use plenty of warm, sudsy water if possible.

Knuckles is right in that removing the valve stem core allows a LOT of air to blast inside, hopefully seating the beads of the tire. Once the beads are sealed, let out the air slowly an being carefull to not bump the tire loose, reinstall the valve core and inflate to the desired pressure. Good luck!

but remember you need an air blower gun and not a tire fixture on the compressor

Also very little volume in a tire that size so very easy to overpressurize. Safety first.
