Good morning,
Thanks for the reply.
The truck is actually a 1990 f350, when I built it I never changed the fender decals.
The tires I'm running are 235/85R16 rated at 3042lbs each.
I spent a considerable amount of time last night looking up wheels and tires. Only way to get a heavier weight capacity rim is to get a trailer rim it appears. I also have read its not a good idea to use one on a driven axle. I started pricing out 19.5 rims, they sure are proud of them.
Has anyone heard of Arrowhead dually adapters? I have a lead on a set, with duallys it would definitely put me in a safe wheel load range.
