All up to you, matter of personal preference. Personally, I wouldnt run 275mm wide tires on 9j since itll look like beach balls. The tires will roll over the side cuz its wider than the rim. 9" equates to roughly 230mm.

Personally, I'd go 225/45-17 or 235/40-17 up front and 255/40-17 in the rear max.
