Aftermarket wheels...how safe are they??

even steel wheels can crack, Mercedes Sprinter van wheels are actually known for this, we've had a bunch fail on our ambulances at work.







Funny you should mention those







I remember as a kid seeing the aluminum Mercedes wheels and wondering why there were little holes in there, in between the bolt pattern







Someone told me that's where they were prone to cracking, and the holes would stop the cracks from splitting the wheel







Not sure if it is true, but that's .what I was told
