DO _NOT_ use this wheel without fixing it.
(sorry about the korny warning, but it is serious IMnotsohumbleO)
Any portion of the wheel is a stressed member.

It will crack further, for sure. That is thenature of cracks, they
propagate. The end of the crack is a stress-riser. The local stress at
the end of the crack can be many times higher than the normal stress in
that area of the wheel, so the crack grows. Eventually you will have a

Sure, this is a viable alternative. The Wheel Shoppe in Detroit would
prep and weld the crack, and refinish the wheel.

No, you need someone who knows how to weld aluminum.

I think you could find a decent used wheel on this list.

Maybe but it won't hold the aluminum together enough to stop the crack.

No, the worst you can expect is a broken wheel, and if it happens at
speed, you could have a serious accident when that happens. Definitely do
not drive with that wheel until it is fixed.
