Default Wheels and tires for a 1966 GMC 1-ton

Good afternoon,

I am looking for recommendations on replacement wheels for my 1966 1-ton. It is currently sitting on the original tires and Split Rim wheels. Understanding that most tire shops will not touch the split rims, what have others done. I have looked at some options, but thought I would ask around.

Thanks

GE

I have wheels off a GMT800 HD. That's what was on the truck when I bought it. I can mimic the size of the wheels that would have been on our truck, which keeps the speedometer fairly accurate. 235/75/R16. For tires I have Hercules TerraTrac CH4. I believe mine are 10-ply. Fairly inexpensive and so far very comfortable. If you don't plan to do any heavy towing and hauling you can use 6-ply tires instead.

Otherwise just about any 8 lug GM wheel should work up to about 2010. The lug pattern changed around then. The older, thinner wheels are better for reducing steering effort though.

Just be aware that 3/4 and 1 ton GM trucks used 1/2" wheel studs up until about 1970, and 9/16" wheel studs since then. Ideally, you'd want to use wheels with 1/2" holes for your 1966 truck.

That's a rather important detail that I completely forgot about...
