Thanks man!
I actually had a new mud rover as a spare and I'm running it now, the guy just doesn't want to trade for a mis-matched set, and I can't blame him.
I even have another mud rover spare that is mounted, that I had forgotten about, but still not interested in the trade without a matching set of 4.
Can't really say that I blame him. Gonna keep looking I suppose.....or break down and buy some 35's
