I don't think so. 325/25/20 is for 20X12 wheels. I think it will be too wide for the 20X11. I think 315 is the widest you can go for a 20X11 size wheel.

But you don't want to run 315's with the (known) available sectional widths or you'll destroy your differential.

You are correct, but It's not the width 315 that messes with the differentials. It's the fact that there is no tire size for the front that can keep the diameter within a certain spec of the rear tires that will screw with the diffs. Kind of goofy...
