Sudden extreme vibration and shaking

[mongo]

So in this case they are Goodyear. So do you figure Goodyear would cover it without issue?

Yeah, it seems like there should be a warranty from Goodyear that Tesla should be able to point you towards.
I found the policy, I think. Warranty terms changed August 1, 2024:

Though not pertaining to the CT tire warranty……..I have had Zero luck in the past with Goodyear honoring their warranty. They always find some reason to basically tell you to take a walk. The tire was disintegrating with steel belts showing on parts of the tire. Showed 2 invoices for warranty alignments from dealer, with tire rotation. All this occurred with under 10,000 miles. It wasn’t just one Goodyear dealer that this happened might I add. Went for a second opinion from another Goodyear dealer and unfortunately I was blackballed because they knew about me going to another dealer. Thank god the original car dealer stepped up and replaced the tires for free “ AS LONG AS BOUGHT THE EXTENDED TIRE WARRANTY”. So I did, then cancelled it the next day.

On my way home from Cape May, NJ. to Pa. I experienced a sudden vibration and shaking at 65+ MPH. Thought a tire was down so I pulled over and checked even though the screen read that all tires were at 50psi. Nothing wrong, started on my way again and sure enough it happened again. Any thoughts?

Just came from 3rd appointment at Discount Tire to try to get tires balanced after continuing problem with extreme vibration at interstate speeds. They discovered that the foam insert was not attached and had bunched up inside the my Cyberbeast's AT tire. It looked like there was never any adhesive applied.

Did removing the foam solve the problem??

I had the same issue and had the foam removed from all four tires. I’ve driven several hundred miles since then and it’s perfect. The bad design is that they put a very narrow stripper glue to attach it versus 100% coverage. So the issue is with the tire manufacturer

Looking at the number of instances with the same issue, looks like this should be a NHTSA worthy problem to be addressed ?

Does it impact safety though, or just comfort?
FMVSS 109 doesn't appear to set requirements on acoustic foam performance.

Based on my research and the tire experts, and even a Tesla mechanic, there’s no safety issues. It’s all about sound deadening, which I noticed a very little difference.

Yes Art138, removing the foam solved the problem. I feel that this is definitely a safety issue when it occurs. The bouncing vibration was so very extreme that I felt unsafe at interstate speeds between 65-80 miles and had to slow down to an unsafe speed for going with the flow of traffic. The vibration was so bad that I was concerned the tire might fail due to overheating.

Found some good info using AI on this subject:

Yes, foam inserts used for sound deadening in tires can sometimes detach, causing tire balance problems and vibrations. This is a known issue, particularly with tires on electric vehicles (EVs) and luxury cars, where reducing road noise is a priority.




Here's why it happens and what the consequences are:

• Purpose of Foam Inserts: Tire manufacturers like Michelin (Acoustic Technology), Continental (ContiSilent), and Pirelli (Noise Cancelling System) use foam inside tires to absorb vibrations and reduce "cavity noise" – the resonance of air inside the tire as it rolls. This helps create a quieter cabin, especially noticeable in EVs that lack engine noise.
  
  
  
• Detachment and its Effects: Over time, the adhesive holding the foam to the inner lining of the tire can fail. When the foam detaches, it can clump up inside the tire, creating an uneven weight distribution. This effectively throws the tire out of balance, leading to:
  • Vibrations: You'll typically feel vibrations, especially at highway speeds, which can be mild to severe.
  • Shaking: The steering wheel or even the entire vehicle might shake.
  • Difficulty Balancing: Tire shops may struggle to properly balance the tire, as the foam can shift even after balancing.
• Common Occurrences:
  • Many Tesla and Hyundai Ioniq 5 owners, among others, have reported this issue.
    
    
    
  • It's not necessarily a defect of a specific brand, but rather a known challenge with this technology.
  • Some reports indicate that certain production batches of tires might have weaker adhesive, leading to premature detachment.
• Solutions:
  • Warranty Replacement: If the tires are relatively new and within the warranty period, the manufacturer or tire retailer might replace them.
  • Foam Removal: A common solution, especially if the tire itself is otherwise in good condition, is to have the foam removed by a tire professional. Many owners report that removing the foam does not significantly increase road noise, and it resolves the balancing issues. The tire can then be rebalanced.
  • New Tires (without foam): Some owners opt to replace the foam-filled tires with standard tires when it's time for replacement, as they don't find the noise reduction benefit substantial enough to outweigh the potential balancing problems.

If you experience vibrations or difficulty balancing tires that have sound-deadening foam, it's worth having a tire professional inspect the foam inside the tire.

No issue for me at 130.
