I’ve acquired 6 Dodge Ram 4500 10 lug 19.5 wheels . Centers from original 18” dual wheels are a perfect fit. I’ve seen a truck already running wheels done this way I’ll try to post a pic when I can find it. 225/70r19.5 tires are common as dirt and very affordable, they’re within an inch of the height of the original 700-18 tires.
I've done the measurements and thought this was possible, glad to see someone finally make 19.5" wheels with original 8 hand hole centers.
You should be able to use many if not all 19.5" rims you may find, not just from a Dodge, measure the inside diameter of donor rim compared to the outside diameter of you original center. Some machine work may yet be necessary for a good fit.
Look at 8R19.5 tires, also very available and they're taller a little than the original 18" tires and still skinny, they look good and you go faster. They look best on a 6" wide rim, but also fit 6.75" rim if that's what you want to use.
Grigg, the dodges are the only one I know of that measure right but I’m sure there’s more. I know the 19.5 GM stepvan wheels I had on my old 1 ton and like I think you have on your GMC are too small. The 8r19.5 would be my first choice but they are just too expensive, not so much for steer tread but the only drive or mud treads available are from the top name brands and you’re talking $350 and up apiece. I know I could go with steer tread tires in the back but it’s just not the look I want. I like these: https://www.tirerecappers.com/tires/mud-terrain-tires/lt22570r19-5-retread-lug-mt/

A quick how to on this new idea would be nice. Looks like a very good option. Do you need to cut out the centres? Thanks
Yes the centers will need to be removed from the 19.5 Dodge wheels on a lathe. The original centers are removed by drilling out the rivets and slitting the rim with a torch or grinder. I’ll certainly write up a how too but it’ll be awhile as I’ve got several projects in front of it and money for machine shop work is non existent at the moment.
