my f250 is an 07 model. it is the older body style. the wheel well openings are smaller than the new body style so you cant fit as big a tire on the truck with out a lift. I was able to fit 35 mud terrains on my stock 20 inch rims. that worked out great for me since i tow often. I had a bead pop off my tire once out at the beach so i decided to change to 17 rims with e rated toyo mud terrains. so far so good.
here is a picture of my truck at stock height with 35 tires on 20 stock rims
here is a more recent pic. sitting on 4.5 lift with 17 rims and 35s.
some of the things i have done to my truck are modifications that would improve the function of the truck.
1. I sound proofed my interior with sound deadening material. this quieted the interior from the diesel.
2. i added bigger pan on the auto trans in order to fit more oil capacity and therefor keep it running cooler which i hope will prolong the life of the trans.
3. added a pan to the rear diff. again did it to keep it cooler especially when i tow.
4. bead lock 17 inch hutchison wheels. the land cruisers and f350s i drive overseas for work have these and know they are reliable so ordered some for my truck.
5. e rated toyo mud terrains in a 35 inch tire. still want to be able to perform off road and tow at the same time.
6. ARB bumper. for protection. i crushed the stock bumper when i bumped into a pole so knew i had to change out the stock stuff.
7. i added the sylvania gold bulbs to replace the stock ones and to me they work great. slightly brighter.
8. ICON level 4 suspension system. i can hit 1 foot deep dips on the dirt roads around here at about 70 mph and just glide right over them.
near future plans are
replace stock fuel tank with titan fuel tank. stock location, stock sending unit and stock fuel gauge and the best part 20 additional gallons which equals to about 650 to 700 mile fuel range.
continue to improve lighting with LED technology.
rear bumper/ tire carrier
rack to carry the families paddle boards.
again, i love crew cab superduties because they are so versatile. my plan was just to improve the truck in order to suit my needs. i personally think that an 8 inch lift will take away from the functionality, and versatility
