Tesla Semi tire inflation patent paves way for pickup truck, Model Y & X’s off-road abilities
During Tesla’s third-quarter earnings call, Elon Musk noted that the company continues to make headway on its future vehicles. Musk noted that he had already approved the production of the Model Y prototype, while pointing out that the company is making progress on the next-generation Roadster and the Tesla Semi. Musk reiterated his enthusiasm about the Tesla pickup truck as well, which he admits is a vehicle he is most excited about.
Some of the improvements to the Tesla Semi appear to have been teased in one of the company’s recently-published patent applications. The patent, which was published on October 18, 2018, and titled “Automatic Tire Inflation System with Thru-Hub Air Feed,” outlined a system enabling Tesla’s vehicles to inflate or deflate their tires as necessary. While several vehicles today already have Automatic Tire Inflation Systems, Tesla’s patent application notes that conventional ATIS have much room for improvement.
“These prior solutions had a number of shortcomings. With some prior art techniques, air was fed through hollow drive axles to a fitting located on the end thereof. The fitting was then coupled to the air inlets of the tires. To couple the air into the hollow drive axles, a rotatingly attached fitting coupled air from an air storage to the inside of the hollow axles. This fitting was subject to leakage of contaminants. These contaminants interfered with the operation of the ATIS and eventually caused the ATIS to fail.”

Tesla’s ATIS patent involves a system that features valves, a rotary air seal, and bearings, to avoid contamination. With such a system in place, Tesla notes that the wheels of its vehicles would likely last longer, and tires would require even less maintenance.
“In order to overcome the shortcomings described above among other shortcomings, an Automatic Tire Inflation System (ATIS) for use with a vehicle according to a first described embodiment includes a controller, valves controlled by the controller, the valves having an air supply inlet, and a plurality of air outlets. Further, the ATIS includes, for at least one drive axle having inner bearings and outer bearings, a channel formed in a spindle, first hosing coupling a valve of the valves controlled by the controller to the channel formed in the spindle, a channel formed in a hub, a rotary air seal residing between the inner bearings and the outer bearings and coupling the channel formed in the spindle to the channel formed in the hub, and second hosing coupling the channel formed in the hub to at least one wheel.
“Thus, as compared to the prior ATIS systems, the ATIS of the first embodiment, significantly reduces contamination in the ATIS air stream. Reduction in contamination extends the life of the ATIS, extends spindle life, extends hub life, and extends serviced wheel/tire lives and extends maintenance intervals.”
While the diagrams in the patent application suggest that Tesla’s upcoming ATIS would be used for the Semi, the applications for the automatic tire inflation system for the company’s other, upcoming vehicles are notable. Having the capability to automatically inflate tires depending on the terrain, after all, would allow Tesla to start giving its vehicles some form of off-road capability. Under-inflated tires are key to off-road driving, since they are capable of flexing more, allowing vehicles to “crawl” over rocks and other sharp, irregular terrain. Under-inflated tires also have a wider contact path, allowing vehicles to gain more traction in terrain like deep sand or soft snow.
For now, Tesla’s vehicles are optimized for city and interstate driving, and while there are accounts of the Model X being taken off-road (EV YouTuber Bjorn Nyland’s extreme driving test sessions come to mind), the company’s electric cars are yet to have features that are specifically geared towards off-road driving. With an ATIS system, Tesla’s upcoming vehicles such as the Tesla pickup truck, and even the company’s SUVs like the Model Y and a future iteration of the Model X, could have the ability to explore areas beyond paved roads. Such capabilities would likely be invaluable, considering that legendary vehicles like the Ford F-150 and the Chevy Blazer established their legacies by proving themselves capable in areas where neither asphalt nor concrete is present.

Tesla Cybercab launch catches NHTSA’s attention who wants to know more
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

Tesla Cybertruck targets job site crews with new Tailgate Utility Track and Bed Gear Box accessory
Tesla launched a $350 tailgate track and a $985 lockable Bed Gear Box for Cybertruck.
Tesla’s Cybertruck team added two more items to the Tesla Shop, targeting job site crews and owners who use the truck bed for actual work rather than just showing it off. The official Cybertruck X account posted the Tailgate Utility Track and the Bed Gear Box within minutes of each other, part of a five item batch that also included a reflective jacket, a spray paint hat and an updated reflective tee.
The Tailgate Utility Track runs $350 and turns the folded down tailgate into another mounting surface. It’s a single aluminum track with a T-slot for sliding accessories and two L-track attachment points, plus two load stops included in the box. The pitch is straightforward: strap down oversized cargo, like lumber or a cooler, that hangs off the back of the bed without it sliding out mid-drive. It bolts onto the existing tailgate and works on every Cybertruck trim.

The Bed Gear Box costs $985 and is a different kind of accessory. It’s a lockable aluminum storage box, 55.78 inches long, 19.8 inches wide and 7.79 inches tall, that mounts to the bed’s L-track rails and comes with two internal bins for smaller items. According to Tesla, at just over 57 pounds empty, it’s meant to stay in place rather than come in and out with each trip, giving owners a factory-fit alternative to loose totes for tools, recovery gear or emergency supplies. Tesla’s listing notes that Long Range and Dual Motor AWD Cybertrucks need the L-Tracks accessory installed separately before the Gear Box will mount, since L-tracks come standard only on certain configurations.
Both accessories lean on the idea Tesla has been building toward since Elon Musk first described the Cybertruck’s third-party attachment strategy at the 2023 shareholder meeting, when he said the truck would ship with mounting points so outside companies, and Tesla itself, could keep adding gear without redesigning the bed. That’s the same L-track backbone underneath the tailgate shield and jumpseats Tesla launched last year, and the off-road armor package that arrived through the same X account in 2025.
Owners looking to round out the rest of the L-track ecosystem, cargo dividers, MOLLE panels, bed racks and similar gear, can find a wider range of options through our Cybertruck accessories collection.
