i finally mouted my 35x12R18 Wildpeak AT3W back to the stock location.
Few things needed to complete this:
-Trimming the back side of tow hitch.
-Removal of exhaust heat shield.
-Airing down spare. I am at 30PSI currently. May need to air down more.
-Use of a wheel spacer: since I have Method 305NV and the wheel bore size is way bigger than stock, the stock spare hanger is a bit too short for the Method bore. I bought a pair of 1.5" wheel spacers off Amazon to reduce the bore size to fit the hanger. I went with 1.5" because it is the thinnest I could find that came with studs to secure the spacer onto the wheel. I only used 3 lug nuts since there's no vehicular load on it.
But at least now I have usable space on top of my Decked.
But one down side is the tire is very close, if not touching, the panhard bar. I might drop the spare and adjust it closer to the tow hitch receiver but driving on the road so far is fine.
