After 4,000 miles behind the wheel of his Tesla Cybertruck, Arizona resident Randy Dunton still loves his futuristic truck. But there’s one problem that has him — and now a growing number of other owners — seriously concerned.
At speeds over 70 miles per hour, Randy says his Cybertruck begins to wobble. And by the time he hits 80 or 90 mph, the shake becomes so intense, it feels like something’s seriously wrong.
And he’s not alone.
Randy shared his experience in the Tesla Cybertruck Owners group on Facebook, and what happened next turned a personal complaint into a much larger conversation.
“The Truck Starts to Shake”
In his post, Randy wrote:
“4,000 miles so far. I love the Cybertruck, no doubt about it, but I’m noticing a strong wobble that seems to originate from the tires or suspension starting at 70 miles per hour, and it becomes quite intense at 80 and 90 mph.”
What makes the issue even more strange? It doesn’t happen every time.
“Strangely, this phenomenon comes and goes,” Randy explained. After visiting a Tesla service center, he was advised to schedule a service appointment. That’s when a theory emerged: the problem might be foam inside the tires.
Foam Inside the Tires? Yes, Really.
To reduce road noise, Cybertruck tires come fitted with foam inserts. But it seems that in some cases, this foam is coming loose, rolling around inside the tire, and throwing off the vehicle’s balance at high speeds.
“The only speculation so far is that there may be a foam insert that is coming loose inside the tire,” Randy wrote.
So, he turned to the community: “Has anyone else encountered this issue?”
Turns out — many have.
Other Owners Speak Out
Rick Sams responded:
“I had the exact problem. The foam in one of the tires came completely loose. Tesla gave me a new tire and installed it for free.”
Maher Sabalbal added:
“I’m having the same issue… vibration at high speeds. It’s subtle but definitely noticeable.”
And then Doron Sam Benarroch dropped the receipts — literally.
He shared a Tesla service report showing that the foam separation in his front tire caused the shake. Tesla diagnosed the issue, removed the tire, rebalanced the wheel, and fixed it under warranty.
The official repair notes read:
“Foam separation was found in the front left tire and has been removed and rebalanced. Verified proper operation.”
Jared McDaniel chimed in too:
“Guaranteed it’s the foam insert. I had the same thing. New tire fixed everything.”
But Is It All Cybertrucks?
Not exactly. Some owners think it might be linked to a specific wheel and tire combo.
Cybertrucks currently ship with two tire types:
- Cyberwheels with Goodyear Wrangler Territory RT all-terrain tires (the cool-looking, off-road-ready ones)
- Core Wheels with Pirelli Scorpion ATR all-season tires (range-focused, quieter, and standard)
Freddy Santiago, a Cybertruck owner who has driven both, says he’s noticed a clear difference.
“I have a Cybertruck with Core wheels… never had a problem. But when Tesla gave me a loaner with Cyberwheels, I noticed the vibration at high speeds.”
His theory? It’s the Cyberwheels + Goodyear tires that are causing the foam separation and the wobble.
A 9th Recall on the Horizon?
With dozens of owners now reporting this same high-speed wobble — all seemingly tied to the same tire setup — people are starting to worry.
“I hope this doesn’t turn into another recall,” wrote owner Sergio F Pereira.
If it does, this would be the 9th physical recall for the Cybertruck — a vehicle that’s already making headlines for early production issues like detaching body panels, which we reported before Tesla officially acknowledged them.
Given the number of reports, the matching symptoms, and Tesla’s service centers already replacing tires under warranty for this very problem… it’s starting to feel like a recall is only a matter of time.
So the question is: Will Tesla issue an official recall, or just keep handling these cases one-by-one behind the scenes?
