Does anyone increase the tire pressure in rear when towing a heavy load? In addition to better MPG i'm thinking it might also relieve some stress on diffs as i know with AWD you want to keep tire DIA. the same???
I know some Subaru manuals suggested increasing from 28 to 41PSI with Foresters and in other years with the same car they omitted it....so much for constancy
