Thanks for the reply, No though, I was discussing both Three and four (five even ) piece wheels in the post, The four (or 5)piece rims found on 1920s thru easy fifties on 1 ton and up trucks that are actually two half's ,cut across the entire rim, with a retention device and they fit on the SPOKES of the hub, Have a 36 COE with them . And in the second half I was referring to SPLIT RING RETENSION RINGS , commonly found on the M35A2 ect ,also commonly now refered to as "split Rims"as knowledge of the older rims fades. OSHA still prints regulation on safety procedures for both. The 1930 rims are still availible for restorations, I don't run any of my trucks commercially and don't fall under DOT regs for commercial trucks , IN NH "private" Antigue plated vehicles over fifty years of age arn't even subject to inspection , nor are vehicles in Alaska registered outside Anchorage city limits , I register in both states. I routine "summer drive" my trucks and have never been even "Cautioned" about them, Mind you I run serviceable tires and keep my rims clean and freshly painted. Sorry I seg-wayed with out being clear , hadn't noticed it until you pointed it out and I re read my post . I do know they are a NO NO in Cali,
