Welcome to the site Joe!

I assume you have tubs all the way to the frame. The frame is 41 1/8" wide nominally at the top of the humps, and about 42" in front of the humps. I usually use the 42" measurement for tire fitment but you might be able to use a little narrower of you measure your actual tub width at the very front of the tire.

Do you know how wide your fenderwell lips are? Most are 71 1/2" to 72". Let's use the 71.5" dimension.

So using 42" and 71.5" each tub is 14.75" wide. I would say you need 1/2" clearance at the fenderwell and 3/4" or so at the tub which leaves 13.5", or about a 345 tire. This tire is going to need a wheel around 11 1/2 to 12" wide depending on sidewall height.
