Grigg,

If you are reading this thread, what type of rim is the original poster describing?

I think my 54 GMC COE with 9.00x20" original rims has the AR-5 style rim. My Goodyear Truck Tire dealer had no concerns or problems mounting Samson tires (and tubes) on those rims.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
