Question Help With Tire Fitment on 2012 F350 Lifted

Bought a 2012 F350 Lariat 4x4 with the FX4 package and had an 8" ProComp Stage 2 lift installed, Toyo Open Country 38x15.5r20 tires and a set of Fuel Throttle 20x12 -44 4.75"bs rims. The tire on the passenger side just barely clears the fender when turned but the driver side catches the fender on the very corner of the tire. If I ever hit a bump while in turn I can expect to be buying a new fender. I really don't want to give up on my set-up I have, but I know something has to change, just not sure what.. I do know I am not putting fender flares on. What would happen if I went from a 12" rim to a 10" rim and went from 4.75" backspacing to 5"? Think that will get me the clearance I need? And would that narrow of a rim wear my tire quicker?

Any Suggestions are welcomed, please.
Thanks in advance for any advice.

(I apologize if I put this in the wrong location)

Question Do I have the answer?

Been doing some research and have come across some interesting information regarding possibly needing an adjustable track bar. As I had stated previously that the tire clears on the passenger side but hits on the drivers side is telling me the axle isn't centered now. The lift kit came with a drop down bracket for the track bar, but no track bar. Correct me if I am wrong but if I am using the stock track bar now and its off just a tad, I would need a stock length adjustable track bar to remedy my issue.? What do you think?

(thinks to himself: sure hope that's it)

A 10" wide wheel with a -25 offset will fix the problem but might be a little small for the 15.50 tire. Your problem is the wheels not the trackbar.

^^What he said. A wheel that is 2" narrower that loses most if not all that width from the outside of the wheel would give you plenty of clearance.

Track bar drop brackets are used instead of an adjustable bar. An adjustable bar may be ideal for extra adjustability if needed but a drop bracket (if the correct one is being used) should suffice.

Take some measurements and see where your axle is at.

You got any pictures of the setup?

Seems like you wouldn't have this issue on an 8" kit with 38's. Especially for the newer trucks, the fender opening is just so much larger. How centered is the front wheel in the wheel opening?

I see quite a few running 37's and 4" of lift, seems like with 8" it shouldn't be a problem at all.

Wow, that looks awesome! Im about to go with a '12 F250 exactly like that, probably gonna stick with a 7 inch and 37s tho.

^^ probably most of the 4 inchers with 37s are only a 37x13.5....hes running a 15.5 wide, could be some of your rubbing issue as well..?
