I'd challenge that gear swap is any more expensive than a tire size swap. 19.5" tires and wheels are NOT cheap. I'd have to say I spent about $3,000 for my 19.5 set up.
Toyo M608Z are $500 each plus.
Rickson steel wheels are about $300 each plus.
That's $3,200 plus any extra charges like tax, mounting, stems, etc.
