Sorry, this is off topic from the 19.5s.
I've already taken the whole thread off-topic, seriously looking at 275s on 20s now. That would provide more capacity than the front wheel ratings, which are 3500lb/ea, for 7K front axle tire capacity (up from 6170).
I considered looking at staggering tire sizes but I think this provides all the additional capacity I'm looking for.
For the spare, looking at mounting a cheap 255/80r17 on the factory spare rim, because it's only 3% smaller in diameter than 275/65r20, so close enough to limp by on.
