42 DC rim question

Tonight I was removing a the rubber from a rear wheel on my 42 DC parts tractor. The rims did not appear to have been filled with calcium and looked pretty decent. When I tried to pry off the old 11-38 tire, I noticed that the rim bent very easily under the tire irons. After folding over the rim in several spots, I decided to cut the rubber off. With the rubber off, the rim felt a lot lighter than I would have expected.

Did the wartime tractors use lighter gauge steel than later models?

Thanks for looking.
 
I decided to weigh it, 55 lbs. Miller tire lists a new rim at 71 lbs. It may have lost some from rust, but not 16 lbs worth.
 
I doubt it is an original rim if it has tires on it. Our 42 came on steel because tires were not available. Wheels were changed after the war, and tires mounted then.
 
Interesting idea, I hadn't considered that idea. Unfortunately, I don't have the build card for that tractor. If the rims were bought aftermarket, it would be plausible that they would have been the cheapest replacements available. Thanks for the reply.
 
If the rim is in good shape what is the date stamped into it? Often near the valve stem hole along with the manufacture. Have used this info to determine if rims were original on several tractors, don't recall which was heavier but think I had decided once that the Goodyear rims were heavier than firestone, or maybe it was the other way around been to long and I was likely using what was best in my collection at the time.
 
I didn't see a date code on the rim. You can see from the picture that it doesn't look bad on the outside, but definitely bent easily by the valve stem.

I wonder if that rim was in a fire? That would make the metal soft, but doesn't account for the difference in weight.
