31 inch MT tires

Looking for a set of used 31 inch MTs....anybody?

I know you said MT's but I have a really nice set of Goodyear 245/75/16 RTS mounted on 16x8 soft 8's with a new spare wheel still in the box for $300 near the Poconos. Two are around 75% and 2 are around 90% and the wheels are only a couple of months old, never off road.
