Crack On Rim

Hello Fellow BMW owners,
I have a 07 3 series coupe and just found a small crack on driver side front rim, these are the original bmw stock rims that came with car.

Question is:

a.) should I and can I find the same exact rim to replace the cracked rim?
b.) is it worth welding it?
c.) can I keep driving on it for a while, the crack is not that big and my tire shop put some glue on it but air is still going out.

thank you,

Don't wait to get it fixed. A wheel disintegrating (even after it had structural damage) is a rare event, but you really don't want it to happen.

It can be fixed at a specialty shop. Should be around $200 to get it in good shape.

Depending on model, you can find used rims, should be around the same price, but it may be difficult to find a single wheel instead of a set.

Typical AM wheels are $800+ a set. Cheaper options exist, but they are often not trusted. This is a better option than buying a single wheel for over $1k from BMW oO

I would not recommend getting a wheel welded, I have seen several wheels, especially 19" wheels on 5 and 7 series BMWs that were welded and the crack continued through the weld and progressed deeper into the wheel. Some of these welds were even done through a dealership or "specialty shop".

Aluminum is known for its malleability, but at the thicknesses required for wheels, it becomes very rigid and strong, a crack completely compromises the integrity of the wheel structure and cannot simply be repaired unless you melt down, harden, and recast the material returning its natural crystalline structure.
