Demon tire/wheel decision??

I would really like to keep the height at about 28". If offset is a problem, I could downsize the rims to 17" if that would help, but I really want the 28" tire in about a 10" to 11" tire width.

His point being....

Tirerack.com shows one tire in a 285-45-18. It's cost is $612 EACH.
