I'll be the first "not so expert" to reply:
My understanding of the reason for "Double stuffing" is to get a bit more "gearing" (actually a bit more roll-out). Double stuffing gives you a slightly larger diameter tire, so the roll-out is slightly higher. I haven't done the math, and I doubt it makes this big of a difference, but it may be like running a 21 tooth pinion instead of a 20.
So... there would be no reason to double stuff the free-wheeling rear tires .
Does that make sense?
