Wow....that's scary. Were the known to be knock-offs or were the counterfeit with Porsche numbers?

Sounds about right for Chinese made stuff. I wouldn't buy replica downhill mountain bike forks either. This would make for an interesting time while barreling down a mountain:

Only a name brand aftermarket wheel. I have a set of BBS RSII on my Turbo and there are many reputable aftermarket brands. If you don't know the brand and can't be sure of the quality then don't touch them.

750KG = 1653 lbs.
Typical V8 955 Cayenne has a rear GAWR of 3748 lbs. /2 and you need a wheel rating of at least 1874 lbs.

I don't know what oem Porsche wheels are rated at, but I'm sure they'll be much higher than 1874. The recommended tire load index is 2271 lbs.

Good point on considering the tire ratings as a MINIMUM rating for the wheels.
750kg would be a tire load rating of 98
our Cayennes' tire specs are around 106 up to 108, which is 950 to 1000 kg.

So yes, rated at 750 kg and then cracking like that, it might not be as surprising as when first seeing the photo.

OP - thanks for the PSA, it might save someone some day.

Did you see the crack first or feel it in how the car drove?

That cracked wheel is made by USARim, in San Diego. They use a sand cast alloy that only looks identical to OEM.

No branding on the alloys, they came with the car when I bought it 5 years ago. I noticed a dark line when I walked up behind the car suspecting dirt-ran my finger along it and found the crack. Didn’t notice any handling impairment but I don’t drive the car hard. Alloy was rear kerbside wheel.

If your looking for some factory replacement options. Give us a call. Would be happy to help you get those aftermarket wheels off your car and into a factory wheel. Thanks

So true lol! Over the last 8 years I have seen several Cayennes with broken replicas. One case was disasterous.
