I have just been notified that my rear wheel is yet again cracked.

Car has been sitting since January while we wait for parts, all of the air in the back right wheel was gone my mechanic noticed that it was sitting funny and went to check it.

This is my 3rd wheel cracked (2 rear and 1 front) all on the same side. Is this a suspension issue? I have been spending just under $1200 each for new wheels and I’m contemplating just buying aftermarket wheels. My local MB dealer said that it would be 2 months before I could get another wheel in.

Any suggestions?

 

What wheels do you have, have had 2 C63 never cracked a wheel, first one had split spoke 18's second one is a 507 so has the forged 19's, but I also don't drive in the winter when the holes are at the worst.

Aftermarket and less you spend a lot are going to be weaker overall and more prone to cracking especially the cheaper ones, but might be worth running something cheaper in the winter if you are cracking the wheels typically in the winter when all the potholes occur.

 

The multi spoke 19's are prone to cracking.
IMHO its because of small aspect (height) tires (30 series on rear) and running higher than normal pressures (std MB for W204 C63)
When I bought my car a few years back it had Multi spokes on and 2 had cracks so I bought a set set off ebay noting that one had a crack.
Put the 4 best wheels on my car and luckily sold the 3 cracked wheels with the worst rash wheel for nearly same money.
But that didn't change anything as cracked both kerb side wheels after hitting a pothole in the rain.
Changed to 18's with 245/275 tires.
Have gone back to 19's again, this time with fully forged W205 cross spoke wheels 245/265 both with 35 series tires.

 

18s I have Conti DWS in back. I was looking at 18in Koning Flow Forged wheels. I might buy the Koning and then some Uber cheapo XXRs or Niche for the winter.

 

Don’t ever buy xxrs. That’s damn near a death sentence.
