WTB: 265/70/18 Tires near South Dakota - Need Not be New - Or Off-Road 17" whls/Tires

[SVO4Turbo]

This is a product of my own stupidity. Didn't rotate my tires forever, so I've got two nearly used up ones. Two are still good. Managed to cut down one of the used up ones pretty bad, but I'm not ready to buy 4 new ones yet. I'd pick up 2 of somebody's used tires with 5/32 or so left. Or, I'd buy 4 if there's still quite a bit of tread left. Or, I'd buy 4 of the Off-Road Pkg wheels/tires if the tires are fairly new. I like the off-road look. Does anyone know if the 17" off-road set requires a different speedo gear or anything different?

Nissan so impressed me with the full size factory spare. It is nice to have.

Thanks All.
