First off thanks man. I love this blue also. Ford has some great looking blue trucks
Yes I have full 35 on an oem rim in the stock spare location. Just cut 2 worthless brackets with the sawzall and it fits even with the hitch and axle compressed.
With my trans being manual and having a different od gear ratio than the auto gives me a higher crusie rpm. At 70 I'm about 2800. With your auto (if it is) and 35"s do 4.56 gears IMO.
