I currently have 18" rims on my truck which is a lot of weight to get rolling. I was wondering what the smallest diameter rim I can fit on there is?

 

Most people say not to go any lower in wheel size because your brakes well get in the way. but I know there are some earlier Ford super duties that had 16s I think. my friends 03 350 has 16s Im pretty sure. but I dont know how your brakes differ from his

 

I know on 05s the smallest wheel you can run are 17s. My friends 04 has 16s. I don't think dropping down an inch or two in wheel size is going to make that much of a difference to justify the cost of doing it.

Why not just get rid of the mud grapplers and run an all terrain? I would think that would be a better weight reduction and less rolling resistance.

 

I've just never been a big fan of large rims

 

I believe that year came with 18's, I dont think you can put any smaller of a rim than factory because the disc brakes will not allow it.

 

Well the '07s came factory with 20" alloys

 

17's, 18's and 20's are all factory sizes. My 06 came with 17's and I have 18" lariat rims on there now. You can not go smaller than 17" though because the brakes are large. They put much larger brakes on the 05+ trucks than the 03/04 trucks.
