I'm hoping one of you guys has a truck like mine and can help me out. Whats the largest tire I can fit on my '05 F350 SD DRW 4x4 CC ? Tallest, widest...etc ? I heard something about making sure they dont rub together on the backs ? The truck now has LT 245/75 R 17 121/118 R Load range E. Thanks again for all your help.

you'll need the spacer plates to keep them from rubbing

I sorta figured that sir. Still need to know the tallest tire that wont rub, or one that will just miss when turning full lock. Thanks for the info tho.

Cant help ya with the tire sizes ours are all lifted even the F-250 & the Excursion wont fit in the house garage

Know anybody that has a stock F350 DRW that might know ?
