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

Might have answered my own ? with this interesting article.

Although, I wonder why Subaru recommended increasing tire pressure in with some Forester models...anything to due with the AWD system and tire DIA???
