The 12.5 inch tire will be an inch wider inside. crank your steering wheel to one side and see if you have an inch of room. You will need a second person to hold the steering wheel while cranked. You will also want to account for the loss of tread on the current tires.
You will be just fine. Just get 10.5s. It really is the most practical size for a ranger. a 12.5 is honestly only good for sand, and it sucks everywhere else. The 10.5 will do snow and other terrains much better since you can put more power on the ground. You will be happy, no doubt in my mind.
3.0 is gay i agree but how is a body lift gay? Why would i be an idiot and get superlift that doesn't get rid of IFS? Spending over 2k on a lift that still keeps the IFS and is barely taller than a body lift? F*ck that. Go deepthroat a superlift shock and make yourself feel better.
why would you raise your cg, then put offroad tires on a frame and suspension thats only stock height?
