I'm sure this topic has a long history, but got lost in weeding through to find my answer....I have a 70, C30 dual rear wheels that have split rims on the inside & later model on the outside...The front have 16.5 wheels mounted to the brake drum without the hub spacers....Its a total disaster..Oh not my doing I bought it this way...Anyhow I located the hubs for the front and now I'm ready to buy 6 new tires but want to avoid using the split rims....What are my options?
