CHOCOLATEART, and anyone else who read that Fleetwood Horror-story--I trust you've now got a grip on it, that a 10-hole 19.5x6 rim is *not* a custom or even terribly rare item. My project-vehicle wears 6 of them; my first experience with anything bigger than stamped-steel 16.5s. I learned to translate "That's a rare tire-size, you'll never find one around here," too. It's a tire-salesman-dialect expression, meaning: "I have none of those in stock."
For the rest--AAAAAARRRGHHH. (an expression of solicitude).
