Tesla Cybercab Patent Reveals Gold Hubcaps and a World-First FWD Staggered Wheel Setup

Tesla's purpose-built robotaxi is edging closer to its commercial debut, and a freshly published United States Patent and Trademark Office filing is giving the public its first official look at the Cybercab's distinctive wheel design. Patent number US-D1130251-S, published last week, protects the ornamental design of those eye-catching gold hubcaps — and a deeper dive into the hardware reveals an engineering layout that has never been seen on a production car before.

What happened

The USPTO formally published a design patent covering the Tesla Cybercab's wheel covers, locking in legal protection for their ornamental appearance. While design patents don't disclose technical specifications, this filing confirms the flat, gold hubcap arrangement that Tesla has shown off on production-bound Cybercab units. Photos shared on X by user @Tslachan offered a rare close-up of the covers being partially removed, revealing how they are actually constructed: the outer ring is made from a flexible rubber material that sits flush against the Continental tire's sidewall, while the center section over the rim appears to be a harder automotive-grade plastic — possibly ABS or polypropylene. The rubber edge prevents friction wear during tire flex, and you can even spot where a trace of black tire material has rubbed off onto the inside of the shield.

Why it matters

Beyond aesthetics, the gold disc covers serve a real aerodynamic function. By snapping over the rim and closing off air pockets, they are engineered to maximize aerodynamic efficiency — a priority that, according to technical analysis from longtime Tesla owner @AlexEdgerton, flows directly from the Cybercab's heavily tapered teardrop body shape, which is optimized to minimize drag. In a vehicle designed to log enormous mileage as a commercial robotaxi, every fraction of reduced drag translates into meaningful savings on energy cost per mile.

The wheel setup itself is arguably the more surprising story. The Cybercab runs 215/60 R18 tires up front and a substantially larger 225/60 R21 truck-sized tire on the rear — all on a front-wheel-drive platform. That combination, per Edgerton's analysis, makes the Cybercab the first production FWD vehicle in the world to run a staggered setup with larger wheels in the rear. Staggered rear-biased configurations are common on rear-wheel-drive performance cars, and some FWD track builds run a reverse stagger to fight understeer, but no production FWD car has ever shipped with bigger rears from the factory.

What this means for EV owners

If you're a current Tesla driver watching the Cybercab's development, this is a window into how dramatically Tesla is rethinking vehicle architecture when performance benchmarks take a back seat to efficiency and fleet economics. The smaller front tires give the steering geometry more freedom of movement, while those oversized 32-inch rear tires spin fewer revolutions per mile — theoretically extending tire life on a vehicle that will rack up commercial-level mileage. The ride comfort benefit is a bonus: a taller tire sidewall absorbs road imperfections better than a low-profile performance tire ever could.

For owners of today's Tesla lineup, the broader takeaway is that Tesla continues to engineer every component — right down to a hubcap — with aerodynamic efficiency and long-term operating cost in mind. That philosophy already shows up across the Model 3, Model Y, and Cybertruck.

The bottom line

A design patent might seem like a minor regulatory milestone, but the Cybercab's wheel filing is a useful reminder of how much unconventional thinking is packed into this vehicle. Gold aerodynamic hubcaps made from dual materials, a front-wheel-drive powertrain, and the world's first production FWD staggered wheel configuration — none of it follows the playbook Tesla has used before. With mass production already underway at Giga Texas and NHTSA recently clearing the way for brake-pedal-free autonomous operation, the Cybercab's commercial launch on Tesla's Robotaxi network is looking less like a concept and more like an imminent reality.
