My driver's side rear tire had a slow leak, and I took it to the local tire shop for a quick repair and side to side tire rotation. Come to find out both rear wheels are cracked and cannot be repaired. I searched the GM Corvette owner's forum, and it's a common problem. This isn't covered by warranty either despite this being the second set of wheels for my vette. The first were bent out of round.
My 2016 Chevrolet Corvette Z06 convertible just passed 18000 miles. I took my car into the dealership to get the faulty brake wear sensors replaced. I also had a 4 wheel alignment done as the inside of my tires were wearing. When they got the car up they showed me cords on my right front tire were showing on the inside wear area. So I had to replace all 4 tires, dealership said 18000 miles from factory tires was great. I think that is an indication of how I drive the vehicle, meaning I don't beat it up nor track it. On my way home I noticed a very strong shaking/vibration in the car. I took the car back and the dealer said my right front rim was dented. I've owned the car since 1825 miles and have been the only person to drive it. I have never hit a pot hole or anything to cause this. So I was shocked when they said my wheel was dented. They then said that this is extremely common on the C7 Corvette. The dealer said they've had customers that have replaced 3-4 wheels. They recommended buying after market forged wheels as replacing them with new factory wheels won't guarantee that they won't bend or crack. A set of forged wheels runs $8000 or better for the car. This is a huge safety issue on a very expensive car that was designed to run on a race track. This could easily cause an accident if the wheel fails why driving. Online you can see this isn't just a minor problem, but one that seems to be plaguing may of the C7 Z06 and grand sport owners. I'm not sure about the ZR1 owners, maybe GM got their wheels right. GM should be replacing all Z06 and grand sport owners wheels and not with the current factory wheels as they are clearly defective. Anyway I just wanted to post my complaint as I think its important for your Agency to see how many people are actually affected. I'm sure there are many that haven't that have had this problem.
Z06 model, black wheels with machined groove, 12K miles, March 2016 build. Hairline crack found on left rear wheel, on the inside lip. Appears identical to problems reported by others here and on Corvette related web sites. First noted as slow loss of air in September 2019. The air loss worsened and was brought in for repair in June 2020. The local shop discovered the crack as the cause of the leak. The wheel was fixed (welded) and is back on the road. I am concerned about the rims safety given the (apparent) original manufacturing deficiency, and also that one has now needed to be welded. The problem appears to have happened on its own. There are no known contributing factors such as accidents, underinflation, racing, potholes or such.
I purchased a used 2016 Chevy Corvette ZO6 & after driving it less than 3,000 miles have had 4 different cracks in the wheels that needed repair. This issue totally blindsided me & had I known the extent of it, I would never have purchased this vehicle. I now do not feel safe driving it & will be attempting to trade in or sell. It is mind boggling to me how this issue has been allowed to go unresolved with no ownership from GM. To say I am very disappointed would be a gross understatement.

Wheel, made of aluminum, developed a crack on the inside of the right rear tire, without my noticing any reason. One day I just noticed that there was a slow lead in the right rear. America's tire wouldn't repair the leak and said I had to buy new tires. I did and the next day the right rear was flat again. I took it back to America's tire and they found the crack in the rim. The car had less than 26,500 miles on it at the time. The Chevy dealer took pictures to verify for GM that there were no signs of the car being raced or abused, but GM declined to replace the rim saying it wasn't defective. The Chevy dealer ultimately sold me a new rim ($1,000 on my car) and charged me $50 extra for a core charge as I wanted to keep the cracked rim so I can show anyone who wants to see it that there isn't any impact marks on the medal in the area of the crack, I.e., the rim just cracked. My car is a very expensive limited edition car with very big rims. I am attaching pictures of the crack, one with the tire mounted and leaking air and two with views of the crack once the tire was removed.
I noticed a vibration that would start at about 55 mph. I took the car in to America's tire to have the wheels balanced and found out that all four wheels were bent. The car has never been raced and has been driven in a normal matter. I have hit some minor potholes but nothing of any consequence.
Had low tire on 11/22/2018. Went to tire shop. Fixed the flat on right rear wheel. They informed me the wheel was bent but would hold air. Took to the dealer. GM would not repair under warranty. I had to pay for repair. The car never hit a pothole, curb, or any road debris. It apparently occurred while car was in motion on city streets.
As has been cited by many owners of the 7th generation Corvette, I experienced 2 bent wheels in February of 2018 when car was noticed to have harsh vibration while driving. In October 2019 tire pressure would not hold and wheel was found to be cracked. This car is driven occasionally and is not autocrossed or driven on a track. Car has only 15,600 miles.
At 26000 miles, left rear tire was losing air. No damage or any impacts at all. Found inner lip of wheel had a hairline fracture. Very concerned about the materials or process used to manufacture the wheels.
Over about 3000 miles this im on my second cracked rim. Dealer keeps telling me I hit a pothole. Definitely did not hit any thing. I baby the car. GM needs to be responsible for this at $1000/rim not to mention the safety implications.
Right rear tire began loosing air. Upon inspection, found that the inside of the wheel had a crack. Replaced all four wheels at my own expense. The vehicle could not hold air for more than a few hours.
Inside right rear wheel cracked, causing air leakage from tire. Cause unknown, not aware of any road hazard or pot hole incident. Noticed crack after wheel dump in water bath to locate slow leak. Have GM extended warranty, dealer would not honor.
Veh purchased 9/2015 and so far I have replace four rear rims and one front. All have hair line cracks on the inside of rim causing radical air loss, vibration and tire wear. Navigation screen flickers and goes on and off at least two times a week and I have to open and close to restart screen. Blower motor went out at 37K miles and the transmission is bucking, vibrating, shuddering and going into 5th gear at 31mph and feels like it is hanging up in 5th gear the clunks down to first at 10mph. Went to dealer, they claimed they did a software up date and things are fine. Left the dealership and came back 5 min later with same issue. Took service manager for a ride and he confirmed the horrible ride. Have to take back on Tuesday 5/28 and it feels like the drive shaft or rear end will fall out. They said it was fine. I hope nothing happens to me or the car.
Both rear wheels on my Z06 cracked on the inside no warping no dings or hits happened took to dealer to replace tires and was showed that both wheels cracked and need to be replaced too dangerous to use have pictures in phone and dealers report and I will hold on to the wheels
Right rear wheel cracked. Less than 17K miles. GM says not covered under B2B warranty. Discovered when tire loss air while driving. Did not hit any pot holes when event occurred/discovered. Model is Corvette Z06, which is not a choice above.
I own a 2016 Chevrolet Corvette Z06. I noticed a wobbling sensation on the highway only to find that my rear wheels are bent and cracked! the car has less than 13K miles on it and is now unsafe to drive unless I spend thousands on new wheels.
