Will this work?

RE: Will this work?
Simple math: Stock offset is 56mm on a 7.5" rim. A 31mm offset pulls the wheel out 25mm (1 inch). Going to 9" wheels adds 1 1/2" in width, 3/4" inside and 3/4" outside. So your net is 1/4" more space inside, but 1 3/4" less clearance outside - more than enough to rub on the fender opening.
So it'll bolt up and work all the way to the 1st corner where you will rub and start cutting down the tire.
Rule of thumb: for 7.5" Rims 45-56MMoffset. For 8" rims, 45 - 50MM offset. For 8.5" Rims 40-43MM offset. For 9" rims 38-40MM offset and rolled or flared fenders. As you go wider you have to worry about both inside and outside clearances more, so the tolerances decrease.
My recommendation is to stick with 8" wide rims with 45-50MM offsets and 225 or 235 section tires. Anything beyond that will require lots of work to fit.
