If I really felt ambitious, I'd just put the motor back on the log splitter. That's the fastest way to remove a tire from a junk rim - just squish the rim. Tire falls off. Takes less than 10 seconds.
However, I don't mind actually working a bit.
When I'm really in a hurry, I can dismount, clean, re-mount, and air up a set of 4 tires in about 25-30 minutes. I've never done all 4 using that tool, the last time I did a set of 4 was in my driveway with the leaf springs and bumper jack.
