Tesla owner cuts open Model X tire to reveal acoustic foam used for noise reduction
A video uploaded on YouTube showcases Tesla’s use foam-lined tires to ensure that its vehicles are as silent as they can be on the road. As it turns out, however, inexperienced tire centers can find it quite difficult to repair Tesla’s tires of choice due to their noise-reducing components.
Acoustically insulated tires were introduced as a result of vehicles generally getting quieter. With the advent of electric cars thanks to trendsetters like Tesla, something as neglected as the noise produced by non-insulated tires become points for improvement. Thus, sound insulating tires started getting more popular. Continental’s ContiSilent tires, which are used in some of Tesla’s electric cars, for one, features insulation that reduces cabin noise by up to 9 dB(A), depending on the type of vehicle and road surface.
The video, uploaded by popular YouTube channel What’s Inside, featured a collaboration with the streaming service’s tech teardown specialist, JerryRigEverything. Dan, the host of What’s Inside, noted that he recently attempted to have his Tesla Model X’s tire repaired in a Discount Tire Center after it got punctured by a nail. To his surprise, the tire center informed him that they do not fix Model X tires, since Tesla uses proprietary components that could be damaged.
Thus, the collaboration with JerryRigEverything. Zack, the host of the YouTube tech channel has made a name for himself from his teardowns of popular tech products (he also tore down a Tesla Powerbank before). The two YouTubers opted to pierce the sidewall of the Model X at first, before opening it up fully with an angle grinder. As could be seen in the video, the insides of the Model X’s Pirelli tires featured a thick strip of foam running around the tire. This strip of foam, as noted by Elon Musk in a tweet last year, could be described as an “internal acoustic foam,” which is designed to minimize road noise.

Tesla’s vehicles are fully-electric, which means that they are incredibly silent on the road. This also means that every sound in any of the car’s components, including its tires, could be heard audibly inside the cabin. This was recently mentioned by Elon Musk in a conversation with Consumer Reports about the Model 3, with the CEO stating that Tesla opted to change some of the vehicle’s interior materials after they were found to cause extra noise. Tesla’s 2012 Model S initially came equipped with Continental’s ExtremeContact DW tires, which are pretty silent on their own. As noted in anecdotes from the Tesla community, later tires, which included the sound-reducing technology, were far more silent and provided more comfort.
As noted by the What’s Inside host, however, Tesla’s noise-canceling tires could ultimately be viewed as difficulties by some tire repair centers. Nevertheless, patching up a Tesla’s tire is actually quite simple, as all that needs to be done is to peel off the acoustic foam before covering up any punctures or holes. Once the tire’s puncture is fixed, a simple layer of adhesive to the peeled off parts of the foam should set it back in place.

Back in 2019, YouTuber Simone Giertz, the self-proclaimed “Queen of Sh*tty Robots,” created a one-off Tesla Model 3 build that took the automotive world by storm. Fondly dubbed as “Truckla,” Giertz noted that the vehicle was actually her dream car — as crazy as that may sound.
Now almost four years later, the YouTuber posted an update on Truckla. And just like every other big project that one probably started, Giertz stated that she actually stopped working on Truckla when the vehicle was about 80% complete. The car is driving though, but a lot of stuff was not really working very well.
Thus, for her Truckla update, Giertz shared how most of her Model 3 pickup truck conversion was essentially completed. Truckla got a lot of detailing done, she got a slight lift, and she now has a functional tailgate. One has to admit, Truckla’s tailgate is pretty darn cool.
The “Queen of Sh*tty Robots” also opted to give Truckla a friend in the form of an automatic robot charger. Unlike Tesla’s rather interesting snake charger from years past, Truckla’s charger would come in the form of a rover, thanks to her friends at robotics platform Viam. Giertz aptly named Truckla’s robot charger friend “Chargela,” which is an appropriate name for such an invention.
Also true to form for Giertz, Chargela’s first encounter with Truckla was just a tiny bit awkward. One could say that Chargela may have just been a little bit nervous on his first try without human hands helping him. Most importantly, the system did work, so Giertz would likely keep using Chargela for her Model 3 pickup.
Teslas are very tech-heavy vehicles, so projects like Giertz’s Truckla are always remarkable. The fact that the Model 3 works perfectly fine despite having a good chunk of it cut off and turned into a pickup truck bed is mighty impressive any way one looks at it. Overall, Truckla will always be one of the coolest Tesla DIY projects to date, so any updates about the vehicle are always appreciated.
Truckla’s nearly four-year update can be viewed below.

A Tesla owner is taking his hobby and love for electric vehicles to new levels by creating what could only be described as one of the coolest EV-related DIY projects to date. The idea for the project is simple: what happens when you cross a supercar with the Cybertruck? You end up with a two-seater CyberRoadster.
Tesla owner David Andreyev, who goes by the username @Cyber_Hooligan_ on Twitter, has spent the last few months creating a Cybertruck-inspired version of the next-generation Roadster made from a salvaged Model 3 Performance. Starting with a Model 3 Performance is an inspired choice, considering that it is Tesla’s first vehicle that has a dedicated Track Mode.
A look at Andreyev’s YouTube channel, which can be accessed here, shows the meticulous build that the Tesla owner has implemented on the project car. What’s particularly cool about the CyberRoadster is the fact that it’s being built with parts that are also from other Tesla vehicles, like its front bumper that came from a new Model S. Recent videos suggest that the project car’s rear bumper will be from a new Model S as well.
The journey is long for Andreyev, so the completion of the CyberRoadster will likely take some more time. Despite this, seeing the Tesla owner’s DIY journey on such an epic build is more than satisfying. And considering that the CyberRoadster is evidently a labor of love from the Tesla owner, the final results would likely be extremely worth it.
There’s a lot of crazy Tesla modifications that have been done as of late. But some, as it is with a lot of things on the internet these days, have become more silly gimmicks than serious automotive projects. Fortunately, car enthusiasts like Andreyev, who just happen to also love electric vehicles, are taking it upon themselves to create one-of-a-kind EVs that would surely capture the attention of anyone on the road.
Check out the latest video in the CyberRoadster’s creation below.

A Tesla owner has demonstrated a rather novel way to charge his Model 3. In a recent video, Sean Callaghan of the ItsYeBoi YouTube channel opted to use a series of off-the-shelf solar panel sheets onto a towable trailer to create a mobile charging unit for his all-electric sedan.
Callaghan planned to use only the sun and the solar sheets purchased from e-commerce platform Wish to charge his Model 3. The solar panel sheets would collect energy from the sun and transfer it to a control panel. The control panels were connected to batteries that would hold the energy—the batteries connected to an inverter, which would then charge the Tesla Model 3.
The entire assembly would provide the Model 3 with about 800 watts of energy on a completely sunny day. However, Callaghan shot the video when weather was overcast, so the entire solar panel trailer build only managed to provide around 300 watts throughout the YouTube host’s test.
To put this into perspective, a 100 volt home wall outlet provides 1.4 kilowatts of power, or 1,400 watts. Therefore, the 300-watt solar panel assembly built by Callaghan was producing less than 25% of the energy of a typical wall outlet. This is pretty marginal compared to Tesla’s 250-kilowatt V3 Superchargers, which provides 250,000 watts, or about 833 times as much power as the makeshift solar panel build.
However, Callaghan’s goal was not to charge the vehicle quickly. He explained the idea came from a previous video where he used a $5,000 Wish-purchased wind turbine to charge his Model 3. He wanted to test the effectiveness and efficiency of the system, which was questionable due to the time it would take to charge the battery fully.
The Model 3 battery pack is 78 kWh, and with Callaghan’s 300-watt system charging his electric vehicle, it would take 260 hours to supply the Tesla’s battery to full capacity.
In the past, electric vehicle enthusiasts have asked Tesla CEO Elon Musk why the company’s vehicles do not contain solar glass roofing, which would charge the car while the owner is driving. Musk has explained that the efficiency of this idea is challenging and likely would not provide an ample amount of range.
When asked about the idea of putting solar panels on the top of Tesla’s vehicles in 2017, Musk responded that the idea was “Not that helpful, because the actual surface of the car is not that much, and cars are often inside. The least efficient place to put solar is on the car.” It also would not be cost-effective for Tesla because “the cost of the panels and electronics, R&D and assembly would never pay for itself in the life of the vehicle, compared to charging from the wall in your garage,” Quartz noted.
That being said, Tesla plans to implement solar panels onto the motorized tonneau of the upcoming Cybertruck. The idea was discussed on Twitter when Musk stated that the optional feature would add “15 miles per day, possibly more” when parked in the sunlight. Also, fold-out solar wings could help capture enough solar energy for 30 to 40 miles a day.
