Ease of replacement depends on the caster used.
If you're in USA, I suggest a "flat proof" wheel from Tractor supply. Easiest to see what will work if you take your tail dolly into the store.
TSC carry a few. The tire of the one I used JUST fits inside the yoke but may not fit every caster. In my case the axle diameter of the caster was smaller than the wheel required, so I added brass bushings from True Value Hardware to enlarge the axle plus another bushing to give the correct offest.
TSC Part number 3553230
Lasted 3+ years so far. Has a little shock absorption, not as much as a pneumatic but way more than a solid caster wheel.
