2012 F350 wheels???

[bwoods001]

i have a 2012 f350 4x4 and am wanting to put 305/65/17 tires on it but i will have to run a wheel spacer on the rear and it will cause most of the outside tire to be out of the fender well. so question is is there a company that makes a extreme inset wheel for the inner wheel so you don't have to run a spacer

thanks
