How are people having a hard time finding tires for 15s?

I just googled BFG ATs and they come in 31x10.5r15 for less than $180 each.

Going from 15s to 20s seems like a giant leap for someone not motivated by looks, but by "tire availability". I would expect someone looking to save money to buy a 17.

Also, your bolt pattern is 6X5.5 which means pretty much any chevy truck wheel should bolt right up since AFAIK they haven't changed their bolt pattern, offsets vary though.
