I was able to put a Milestar MT and BFG KM3 MT in the spare tire mount with about the same clearance you have. Much better than keeping inside the bed.
I could not get a 37 1350 Maxis razor tire to fit, it was hitting the receiver and track bar I even let air pressure out to 7 pounds and still would not fit, I did get it to squeeze in but it was totally buried into the track bar.
