Basically, I want to run the biggest tire possible for a budget lift. Before I order tires and wheels. Can I run 33 x 12.5's with a 2" Rubicon Express coil spacer kit (already installed) and a 3" body lift (not yet installed)? Is it as simple as going high enough or is there more to it, like backspacing, rim width, etc.? If not, with that senario, what is the biggest tire I can run for roads and light off road use?
