I know tires again.... Ive read the sticky posts etc etc. I just have one question that I didnt really see answered there. How wide of a tire can you put on the stock Ford 7" wide rim?? I have a 04 Heritage with 16x7s and may just stay w the stock wheels but wanna go w the biggest tire I can. Tb turned and 2" blocks so i have plenty of room. Thanks

 

I had 315's on factory 7.5's on my F350. These are 285's on 7.5" fx4's

 

A guy at discount said they don't like doing but they put up to +5" on tire to rim size. So in other words 8,9,10,11,12 tire width can go on there if you have clearance.

 

Tlongest...are those 285x 70s???

 

Im running 285s and will be running 315s on the stock 7" wide

 

are you leveled with 285s or are you stock with 285s in this pic?

 

LT285 70R17. I cranked the T-Bars about an inch. Not quite level, but I pull a trailer pretty often so I like having it level when pulling. Plus my ball joint angles are still good.

 

ok thanks, u notice any difference in mpg with the 285s? btw thats a real good looking set up u got there

and to the op, i dont know the width but i believe one member on here is running 37's on the stock fx4 rims-its a green stepside, very nice truck too

 

I have 285/70/17 as well and no rub and havent cranked the tbars at all either. they fill out well and give it a better look than my 265/70/17s
285/70/17 BFGs

First pic is how my truck currently sits with tbar crank with 285/75r16 on stock rims, second 315/75r16 and they rubbed on the lower valence and frame at full crank and inside of box when fully flexed, but that's because of the stock offset
