See post #3, related threads. I added link to a thread that has a video that shows how you could diagnose a bent wheel. This is really eye opening, I could under stand an old 10 speed bike wheel bent after jumping a curb, but not an expensive car from driving on decent roads.
My wheels are pristine until spun.
GM tolerance for runout is 30 thousands.
Didn't Johnny cash have a song, “ I here that corvette comin, tire slappin round wheel bend ...”
If you have experienced a bent or cracked wheel on your C7 Corvette, please check the list (post #1). If your screen name is not on it, reply to this thread and I will add it.
State the following:
(please use example after #4 for formatting your info. This will make it easy for me to copy/paste rather than typing your info):
1. Approximate date that you became aware of the issue.
2. Your username
3. Details of your issue, i.e., 2 bent and 1 cracked wheels.
4. Year and Model of C7 (ZR1, Z06, GS, Stingray).

All 4 of my wheels on my 17 Z vert were found bent and out of round at 4600 miles and repaired by wheel repair shop on 5/25/19. After my trip to Carlisle on Interstate 81, the vibration returned and was even worse this time. At 6100 miles. And the driver side rear wheel is now slowly losing air. It’s a waste of time to bring it to the dealer, only to be told the wheels won’t be covered and furthermore they replacement wheels aren’t even available for purchase. I’m shopping for forged wheels now.
Kudos to Scudz for putting this list together. The ones that flame you haven’t experienced the problem yet. But they will...
As an aviation accident investigator, I can only say that each and every one of these owners with cracked or bent wheels should be filing with the NHTSA. Do not assume that they will file your reports in the circular file & shredder. The transportation safety arena is one of the few remaining areas in government where folks are well trained and highly professional. They take safety very seriously as each of us should.
I just purchased a 2017 Z06/Z07 this week and I have already filed my NHTSA Vehicle Safety Report. Why haven’t you? I included links to this thread and the Car & Driver article. This is a very serious safety issue, especially considering the performance parameters of the C7 GS and C7 Z06 vehicles. Tadge and GM are running a “cover our asses smoke blowing con game” and are endangering people’s safety and welfare and very lives.
I am am a long time big time supporter of Corvette and of Tadge and his team. But these behaviors are simply unconscionable. Yes, they screwed up on designing the Z06 engine cooling systems for track performance use which they promoted heavily. But, bad as those behaviors were, generally speaking, people’s lives were not put at risk.
But, this incompetent design and manufacture of high performance wheels does put people’s lives and health at risk and at the least requires horrendous expenditure of many thousands of dollars to correct, and in many cases continuously correct GM’s failures in attempts to keep both their vehicles and America’s highways safe.
Do not blow this off. Do not simply run out and buy some forged wheels and forget about it. Each of us has a responsibility to work to force the correction of any serious design flaws or safety issues that we encounter. Forget about your pocket book. That is not an issue that the NHTSA or anyone else will respond to adequately. But, they will respond to safety issues and such responses will likely alleviate the corresponding financial issues as well.
You must communicate your outrage over serious safety concerns. Again, forget about your wallet nobody cares about that. Fix the safety shortcomings and other issues will simply resolve themselves.
Tadge and Mary and the rest of GM execs are fervently praying that we will eventually get frustrated and go away and thereby prevent this from becoming a seriously expensive and embarrassing example of GMs ongoing habit of putting their profitability and executive bonuses ahead of consumers lives.
It is about safety. It must always be about safety. Please click the link above and file your NHTSA Vehicle Safety Complaint today.

I would like to thank the above poster for his thoughts. He speaks with knowledge and experience. This is most definitely a SAFETY issue. And, should be approached from that perspective.
I have been following these bent/broken wheel threads. That issue is the sole reason why I purchased a Z51 instead of a GS. I sincerely feel for my Corvette brothers who are going thru this BS with GM. Hopefully, there will be a satisfactory resolution for all of you.
Sorry, we can’t sell you a set at $3,900 bucks because we don’t even know why they are on back order.
GM pays about $150-200/wheel for those wheels, that is the level of mass produced product quality you would be getting for a $3900 counter/retail price.
9/20/2019 TexVette 2018 GS. 17,000 miles.
1 rear wheel, 3 cracks..1/2019. West side Chevy, Katy, TX replaced no charge. Yesterday, rear tire was losing air. Took it to Discount Tire. 3 cracks in the wheel.
Have not reported yet.
Ordered a new set of Signature forged wheels.
Hopefully this will solve my problem.

Did you have the extra wheel and tire insurance? If not, how did you get GM to cover the wheels?
This was presented to me when I bought my 17 GS as only needed for a fluke wheel/tire issue. Initially, I thought that this extra insurance was odd because I never heard of it before. I asked the salesman, “Why are the wheels weak and going to break?” Little did I know.

This is most definitely a SAFETY issue. And, should be approached from that perspective.
