Thanks Guys!
I think I'm gonna go with the 235/65 R-17s, just to be on the safe side. When I get the truck, I'll post some photos in the gallery. (I bought it on E-bay and am still waiting for it to show up.) I'm having a hell of a time not buying everything I want for it until AFTER it arrives. The new rims are already ordered, along with chrome bumpers, new grill, new mirror, other little stuff. Thanks again.
