Also, if you have not done so, look through this thread. It describes all years of Rangers and how much lift needed for a specific tire size. (As well as pics)
Chart of maximum tire size
31 inch tires are usually plenty enough for any Ranger to do the basic things, and they will fit 100% stock on any Ranger from 1993-2011.
I don't have any experience with Rangers prior to 1998, but it's when you decide to get into the big boy tire size, you will need to move things around to get them to fit.
It's also not just the lift, you will also need the correct rim backspace so they don't rub the inside of the truck near the frame area.
