15x12 Rears on a 05 4x4?

I'm wondering if I can run 15x10/12 on the rear of a '05 4x4?

I have a set of paddle tires id like to run in the dunes but I don't know if I can get a wheel that would clear the rear brakes.

Thanks

 

I don't see why a 15 wouldn't fit on the rear. The rear drums aren't big at all, maybe 10 or 11 inches diameter at most.

 

How wide are the tires, to necessitate a 12" wide wheel?

 

Really freaking wide paddles. My buddy doesn't remember if they are 10" or 12". I'll check it put this weekend when we dig them out of storage.
