Im gonna go on a limb and say no. From what I have read, 35s barely clear.
I have an 04 F250 Harley Davidson with the stock 18s I will be attempting to put a 2.5 leveling kit and 35x12.5x18 Cooper STTs or Toyo MTs.
I have done much research and it seems that Its a 50/50 whether or not 35s will work, so like I said, Im pretty sure 37s are a no-go. Maybe someone else can chime in with the 05+ coil spring front end, I believe they will rub the fenders and radius arms tho.
That wasn't really the question. The question was UNTIL you get it leveled, I'm gonna say the answer is no. I bought my 2005 F250 already leveled, my most recent set of tires were 37x12.5x20 Yokohama Geolandar ATS on factory Harley 20" wheels. When the tires were new they just barely rubbed the lower rear wheelwell on both sides at full lock. After a few thousand miles that disappeared. A wider 37" would most definitely have radius arm contact. Mine have polished vertical stripes on the arms but I have never heard or felt it. Keep in mind that tire sizing can vary from one brand to another and even between different tire models in the same brand. My tires work with a leveling kit but it is certainly crowding the limits in all directions. They might also be a tad shorter than other 37s which could be the reason I was able to get away with it. I don't believe that 37s would work on a stock truck under any circumstance and any wider, taller, or more aggressive than mine and they don't make sense for a leveled truck either.
I have a 4" lift with 35s and 37s wouldn't fit without sheetmetal contact. Sheetmetal, not inner fender or leafs, sheetmetal. If you don't mind using a BFH or a sawzall on the trailing edge of your wheel openings, then 37s are going to need a 6" lift. A simple square tube spacer between the frame and bumper works wonders too.
The OP'er has a 2006 truck. The suspension is completely different. Still doesn’t change the fact that the 37's would not fit without a lift, but I have seen TONS of trucks run 37's with 3" leveling kits on the 2005-up trucks.

I appreciate the advise guys. This is all new territory for me. I went and got me some black dropstar 645 wheels and Im just going to go with some 35's and a leveling kit. Hell its only 20-80 bucks depending on which one you get. Im thinking that a 2 1/2 inch leveling kit will work just fine. May have to shave a little off the bottom front farring and pull back the rear inside fender a little but that should work.
It was worse with trail grapplers. Just changed wheels and tires and went with the dune grapplers. Rarely rubs now. If I'm turning and not on level surface.
How much clearance do you have from ur front bumper with the 6" lift? I have 4.5" on mine and wanna put 37x12.5 and maybe have to trim the bumper a little
I have a similar issue. I am currently running 35/12.5/18 Toyo M/T with a zero offset and 3 inch lift (no rubbing). I want to go up to the 37/13.5/18 tire, but a tad nervous. Anyone have ideas or some pictures?
