Has anyone here suggested a bad weld job yet

No.
Consensus is that it's a bad rim job.

Probably best to read the thread

Or better yet explain to us how its welded there?

[bjstare]

I'll certainly be checking the welds when I see it in person this weekend.

There are no welds in that area. The only area that is welded is where the center is to the barrel.

IF for some stupid reason there are welds there then those rims are really fucking dumb and dangerous.

Its the welds.

Too much torque on the launch

The tire wear is going to tell you a lot. If something didn't cut the wheel apart, it would make sense that horizontal loading of the wheel caused the metal to work harden and tear. If toe is out of spec, it is going to push the wheel/tire down the road at an angle putting more load on the face of the rim. This will cause a saw tooth wear pattern on the tire.
From the picture, I see that these wheels are not hub centric. That means that the wheel is going to be centered on the hub by the studs and nuts. Sometimes when you bolt on steel wheels, the taper on the nuts don't engage the taper in the wheel and it takes some finagling to get it to seat properly. Look closely at how the nuts are seated in the broken off part of the wheel on the vehicle. This will cause the wheel to be off-center on the hub. It will put diagonal wear blocks across the tread, just like a worn out shock.

I'm really curious on what caused this. I have seen alloy wheels break out the center from a impact, but steel wheels just bend like a mf.

That all makes sense - but wouldn't that result in some type of shimmy through the steering wheel (or a pull to one side if toe was that far off)? It previously had neither of those symptoms.

typically if the lugs arent seated properly they'll back off and oval out the holes and break studs or the studs will rip through, i've seen it plenty of times (also caused by over torqueing cheap wheels which crushes the seat), i cant imagine this clean break far from the studs is due to improper wheel installation.

Most of the time you will get a vibration with the nuts not seated properly. When toe is out far enough to cause wear, the vehicle will be really squirrely, it will be all over the road.
It's some things to look out for.

I will get a few every year that are tight but not seated. The amount of vehicles I have repaired with loose or fallen off wheels is probably in the hundreds.

Edit, I'm not saying the nuts are loose. The nuts may be torque onto the edge of the wheel taper and not into the taper it's self.

If you are still at work, fire up the Google machine and look up Rusty Trombone.
You might be wrong.

OP did a rim job trying to end his MIL.

That's advanced art room stuff right there.

Yes. That's perhaps more Art Foyer or perhaps even Art Parlour activity.
