78 Dodge chassis Wheel change (its another one)

I posted before about changing tires, but never figured out the exact answer about if keeping the 16.5s and going from 8.00 to 8.75 would work.

Now I am talking about changing wheels, I just found a set wheels on another camper (same chassis) in the 16 inch. They only have 6 and want 50 each.

I am considering it (they are holding them for me) but what tires would work to replace my 8.00 X16.5 in a metric tire for a 16 wheel.

I need to find out what would be a good no rubbing tire for my 78 dodge class c dually.

A tire store should be able to help , perhaps better than anyone here at the forums , they will also need the load rating ( E or G ) or the load capacity ,
3,000 pounds at 90 psi , for example, from your current tires, and the installed height . You should also check the rims your considering purchasing, to make sure the maximum inflation allowed is equal to the tires your considering, that info should be stamped into the rim , near the valve stem.
Also some of the older 16.5" Dodge wheels used a special lug nut , with a different taper angle than the older 16"wheels and the newer rims went to a flanged lug nut, that may not fit your wheel studs, so very important to get all the info you can before shelling out $$$.

16.5 is becoming an obsolete size, and going with 16 inch would be advised. $50 for 6 wheels is a good price, make sure the center hole over hub is the right size and lug pattern. Just use the right lug nuts to fit the wheels as suggested.

A tire shop can verify the metric replacement, but I guess a 225/75R16 would be close and is a popular size used on new dually trucks. Alternative sizes are 235/85R16 and 245/75R16, again the tire shop can help you out. If in doubt, get higher load range.
