Re: 20 x 12 rear wheels

Here is a truck I found awhile back w/ 20x10's and it looks like a fairly tight fit.. 20x12's may need some tubbing done.

Re: 20 x 12 rear wheels

I have measured and a 12" wheel will fit between the outter wells and frame but the inner tubs will need worked.

Re: 20 x 12 rear wheels

Have taken measurements and they will fitt,

Will need to widen inner tubs and also cut out part of the outer part of the tub where it joins the fleetside, & relocate the outer arch supports.

Re: 20 x 12 rear wheels

Did you widen the rear tubs or the outer inner arch ?
