My guess is that you MIGHT have a 8 lug 6.5" diameter bolt pattern, same as used on the 1985 - 97 F-250/350.
This is one place that lists the bolt pattern size and center hole diameter. It is lug centered bolts, meaning that the lug nuts keep the rim centered on the drum. Hub centered rims require the center of the hub fit exactly on the center hub, while the lug nuts do not keep the tire from moving around.

The chart at the bottom of the page shows that 6" wide rims should be used with 225 to 235 mm wide tires and 6.75" wide rims for the 245 mm wide tires.
If you have single rear wheels, I still would recommend the 3,042 pound rated 235/85R16E tire such as my motorhome has or a 245/75R16E such as the E-350 van uses, also rated at 3,042 pounds. If you have dual rear wheels, then you will need to find tires from a dually van or truck with your bolt pattern. Probably a F-350 from 85 - 97 or E-350 of about those same years. The F-450 and F-Super Duty (yes that was the F-450 before it became it's own number in 94 or so) have 10 lug rims, and rims are only rated at 3050 pounds at 90 PSI. While the 8 lug rims can be rated at anything from 2,200 to 3050 pounds, but will fit all the different models of trucks and vans.
