That's standard procedure in any tire shop that mounts truck or implement tires.
Yep.
That's not redneck. That's been the way you inflate stubborn tires since they came out with tubeless tires. I took a job in a shop mounting tires in 1986 and that's one of the first things the old timers taught me. Squirt ether in it then stand back a few feet and toss a lit match at it.
