wheel back spacing

[yorkgulch2]

I just bought a set of 395/85r20 goodyear mvt tires and am going to order wheels next. I know there was a thread that addressed minimum backspacing on 10 and 11 ich wide wheels but I can't seem to find it with a search. What is the minimum backspacing for the front wheels with 10 inch rims with the above tire that gives chain clearance and still keeps the track as narrow as possible? Also I only plan on chaining one rear axle since clearance is minimal between axles. Thanks

Thanks I have been told 6 inches of back spacing is safe and will probably go with 6 or 6 1/2 inches. If you don't do a hub flip on the back axles, would the back wheels track the same as the front if you mount the wheels reversed (4 inches of back spacing)?
