Considering PU has the aero of a brick, I don't think you will notice any change due to offset.
That being said - and considering you have a long commute - you will probably be way further ahead economically if you stick with the original P235/75R15's, and chose a good wearing tire in a LRR.
If you want to move up in rim diameter for other reasons, then there are a whole range of options. Directionally going up in rim diameter is going to help dry traction, handling, and RR, do nothing for wear, and hurt wet traction, snow traction, ride, and cost. But most of these are fairly minor, so it just becomes a matter of do you want to spend the extra money.
