I found my 15x10 steelies on eBay as well, and it was dirty cheap...actually, the 5 + tires were probably lb/lb chepaer than dirt.
Anyways, they are durable as ****. This past weekend, I somehow managed to bent the hell out of the rim, enough to completely deflate my tire within 3 minutes and skip the bead. Went hoke, got a block of wood and a BFH and bent it back. It's still noticable as the spare, but you can bang em back into place. They ARE quite heavy though, as opposed to your pretty street-driven aluminum alloy composite wheels.
