Mostly about looks, but bigger rims can accommodate allot bigger tires and bigger brakes
All depends on brakes and gears and clearance you have, but I had 265/70/R16 at first on my truck, and I now have 35" tires on 17" rims, I notice a difference when accelerating or stopping but the stopping power is still good and my Edge tuner makes up for stock gears, 6" lift helps clear the tires.
For a stock Ranger I would probably go 16-17" rims on 31-33" tires I think you would be safe, but there is always offset and backspacing to consider, most dealer's know what will fit or not
I only drive in the city, to get out of it!!!
