You should shop around if the FJ wheels are what you want. I've seen them for a lot less than $500. Keep an eye on
Toyota FJ Cruiser Community as there are some great deals there on stock parts. For instance:
$600 gets you wheels and BFG A/T's:
Wts:17" Oem Wheels + 265/70/17 Bfg At - Toyota FJ Cruiser Forum
$350 for wheels:
FS (Socal): 5 OEM Alloys. - Toyota FJ Cruiser Forum
$400 for wheels and stock tires:
FJ Cruiser 17" Alloy Wheels, Tires & Lug Nuts - SoCal - Toyota FJ Cruiser Forum
$300 for stock rims:
WTS:OEM 17in Rims,Rack,TireCover,RunningBoards,SkidPlate - Toyota FJ Cruiser Forum
All you gotta do is wait for a set that's near you, shipping I'm sure would be high. Those links are just from the first page or two in the classified section, so I'm sure with some digging you could do better.

As soon as I can get my lift installed, I'm going in for 4 255/75/17 Hankook Dynapro ATMs. I started to get the Goodyears, but I can get these at a local shop for less than $100 more, so I think I'm gonna give them a try. Should I go ahead and move the fender liner before taking it in for the tires to be put on (will have ~1.5" lift in the front)?
