Welcome< Bulldog99, to Bronco Zone!!! You want the least amount of backspacing to limit the amount of tire rub on your radius arms when turning. In general, 3.5"-4" is the backspacing you want, so the 3-5/8" Mickey's would be better than the 4-1/8" bs. I had 35x125.50R15 Mud kings on Mickey Classic 15x9" rims with 3-1/2" bs, and the tires only rubbed on the radius arms at full steering lock. I did have the Skyjacker extended radius arms that are bent inward to help with tire rub, so if you have the stock radius arms and drop brackets, you will get tire rub before full lock. Either move the steering locks in, or just don't turn all the way to one side or the other. You'll get the feel of it after a short time, and still be able to turn 80-90% of stock. JSM84

go with the shallower (numerically lower) backspacing. to give you an idea of what that really is, thats how far the actual mounting pad of the wheel (where the lugs slide through) is from the inner lip of the rim. it kinda determines how far the tire actually sticks out
