Crack in wheel

[EldIr]

So I noticed a slow leak had developed in one of my tires. Since the tires were new last year, I thought maybe a valve stem. I took it off and put it in the bathtub and found a small crack in the wheel. They are only 50psi tires, same as original so it's not too much pressure for the rim. Is this common? I've owned a lot of trailers over the years - many with rims much older than these - and I've never had this happen before.

The crack is about 3/8" long in the area circled. It's not where the center is welded or near an edge. Just right there in the middle.

Rim manufacture has gotten better, or so I think, in the States since then.
One or the primary reason they coat both inside and out or at least the inside is to seal any potential leaks in cast aluminum wheels.
Forged are denser and less prone.
If one of them is leaking in this manner the others may. They maybe the cheapest they could find from China.
Replace them with forged.

These are steel, not aluminum.

Good thing you caught it before a failure.

I plan on replacing it. At least the wheel is less than half the price of the tire. Of course much more than a valve stem would have been:(

Rare but not unheard of if you work around tires.
Get a new/used wheel and move on.
