There seems to be a wide spread issue with the foam on the interior of Ionic 5 tires, Michelin 235/55/R 19. The foam dislodges from the interior of the tire and causes severe vibrations when driving at over 60 mph. The issue causes the tires to be unbalanced and can cause damage to the car. Wondering why Michelin doesn't address this issue and issue a fix other than stripping the tires of foam. My Hyundai dealer told me this is an on going issue and they have received no guidance from Michelin or Hyundai.

On [XXX], while driving north on [XXX] to Michigan, I stopped in Carmel, IN to charge my 2023 Hyundai Ioniq 5 SE RWD vehicle. After charging, I reached 45mph and immediately experienced violent shaking of the steering wheel and seats. The vehicle was immediately driven to Hyundai of Carmel for inspection and possible maintenance. A service technician drove the vehicle and experienced the issue, but could not recommend a solution. The vehicle was driven back to Louisville, KY (home location) and taken to a Tire Discounters the following morning. At Tire Discounters, a technician drove the vehicle and experienced the same behavior, but could not provide a solution. Numerous trips to multiple Hyundai dealership service departments and tire service centers (Big-O-Tires and Tire Discounters) resulted in no solutions. After extensive research, a potential solution was identified by the vehicle owner relating to the noise-isolating foam located on the inside wall of the tires. There are numerous reviews on Michelin's website documenting this specific issue with the tires. A call to Michelin costumer service successfully concluded with a warranty claims number. However, none of the previously mentioned tire service locations would investigate because the vehicle only had 6,400 miles and the Hyundai dealership service departments refused to address the problem. Ultimately, Pep Boys accepted the Michelin warranty claim and found that three of four tires (Michelin Primacy 235/55R19 101H) that came as part of the original vehicle purchase had the internal isolation foam disconnect from the tire belt and gather in a central location inside the tire. There has been no evidence of notices or information from Michelin to dealerships or service departments regarding this issue and the potential for dangerous driving conditions or damage.

Michelin Primacy AS 235/55 R19 - OEM tires on Hyundai Ioniq5 acquired new in September 2023 - mileage at the time of incident 10,800 miles Front tire started went off balance causing steering wheel vibrations and shaking that increased with speed - car was not drivable above 55MPH due to excessive shaking and vibrations of steering wheel - this presents safety concern as it may lead to loss of control and excessive wear and tear on other suspension / wheel components. I took the vehicle to a local tire shop (Town Fair Tire in Norwalk CT - authorized dealer of Michelin tires) - got wheels rotated, balances and alignment adjusted. The issue persisted - on the second visit tire shop dismounted one of the tires and discovered internal foam band unglued and clumped on one side of the tire causing off-balance. The shop recommended removal of the foam material and rebalancing of the tire to correct the manufacturing error.

My car has 16000 miles and originally came with this exact tire brand. Apparently, because I drive an electric vehicle the tires have sound dampening foam on the inside of them. They are supposed to break down slowly with time however the last four months I have had two incidents where the foam became unglued from the rest of the tire, balled up, and caused a huge amount of shake in the car as I drove at speed 60 mph or higher. It did not affect low speeds. This is a safety hazard. The first time it occurred, I considered an outlier and Michigan did replace the tire. The second time it happened, only a few thousand miles later I asked that the foam be removed from the tire as I am concerned that this is a safety hazard moving forward. Michelin needs to have this tire recalled. I asked the Hyundai dealership if other ionic five drivers with the same tires had come in with the same issues. They said absolutely we see it every day. Why is this tire still on the road. I reached out to Michelin and they Refused to refer me onto anybody to discuss this further. They also refused to pay for the foam removal process. That is why I-??ve decided to involve you. Please feel free to contact me at [XXX] to discuss further.

Sound deadening foam inside the tire delaminates and causes SEVERE wheel imbalance. This is a widespread issue on all the Hyundai Ioniq 5 forums with this tire. Mine cost me $300 and countless hours to diagnose. IT also severely impacted the cars handling and prevented the car from driving over 46mph (in my case), which is extremely dangerous on interstates. My local tire shop balanced the tires with the maximum allowed amount of weights, but then the vibration was still there at 59mph. The Hyundai dealer then diagnosed it and they charged me $180 to do a dynamic balance. According to their results, the tires were "bad" and needed to be replaced. I went to Costco to replace the tires at a cost
