I need some help with identification of the wheels in the following pics:

This one is on a 56 F350 cab-chassis dually. Not much pic of wheel, but the tire size can be seen as 7.00-17. Could this be an original wheel? The 17" wheel size tells me it's not a 1 pc drop center. Any definition in the pic to tell if it's 2-piece side ring or "widowmaker" design? If not, if it's stock original, does that define the wheel type?



The next pic are of spare wheel/tires bought for the same F350 cab-chassis. Tire size not visible ... but hopefully pic of wheel should provide definition of wheel type??



Thanks, Jim

 

The bottom picture looks to me like a lock ring. Top picture does not appear to be a "widowmaker" to me. '56 F350 DRW should have drop center 17.5s so far as I know.
Neither picture is very good for id. The resident wheel expert will be along shortly.

 

The top is not a 17.5" tubeless, but I can't tell if its a widow maker. Maybe post a better pic of the area where the center meets the rim. As said, the second one is a side ring/lock ring style. Stu

 

These are pics I requested from the owner (300 mi. away) to determine the wheel type on the truck before purchase decision. After much conversation, he still doesn't seem to understand what I need in terms of pics. I was hoping the tire size would be 17.5 which would indicate the desirable 1 pc tubeless wheels, but the 7.00-17 is clearly there, so it's 2 pc of some type. All 1pc tubeless were half sizes 17.5, 19.5, 22.5 etc. as far as I know. I may not be able to get better pics from him, so I may make the trip to see for myself.
The spares (2nd pic) looked like side lock ring to me but I couldn't find the split in the ring to confirm (probably located where pic is cut off - my luck). If these are side lock ring 17's, they should not be dangerous like "widowmakers", yes/no??
If I try for more pics or make the trip myself, any tips on what to look for to determine which style they are.
I know the front & back appearance of the tubeless 17.5's #73230 (6 hole) & #79120 (3 hole) when I see them, and there is also a 2pc side lock ring 16" - 6 on 7.25" wheel that is ok to use (used on 60's Ford, IH & Dodge), but I know nothing about any 17" - 6 on 7.25" wheels.
Any further education would be appreciated.
Thanks Ray & Stu for your help on this request.

I try to never say never, but I don't know of any 6 x 7.25" pattern 17" wheels that are not widow makers. Strong chance they are. Stu

 

So if the spares (2nd pic) are 2 pc side lock ring, they are probably 16", not 17"? Jim

 

Right. Stu
