6 fender flares

What do you have to do with his Ford Ranger when you put 33 "rims on it?
I have a 2000 ford ranger 3.0L V6 (stock RightNow all) im getting a bit of money during the summer and put a 6 "Camburg lift suspension on it and the burning of the defenses and put 33" BFG in it. I was wondering if theres anything I have to do to support the truck 33 "tires. as regearing" I have no idea what it is. maybe someone who knows a little about this can help. Thank you.
1. 33s will fit without the 2 flares. Use the table to find what his new team should be with your current tire 33s and gear their baseline. It will be a real dog if you do not return to fishing gear. 3. Bad news, you need a ring and pinion for the front and back and you pay for two sets. Welcome to the world of four wheel drives.
