Porsche Taycan wheel and tire size revealed in pre-production prototype sighting
Porsche has stated that one of the Taycan’s primary characteristics will be its capability to be driven hard on the track. In order to do this, the upcoming all-electric four-door would have to be equipped with powerful motors, a well-balanced, hefty battery, and capable, high-performance wheels. It takes some serious rubber, after all, to ensure that the Taycan stays planted on the road when it’s ripping through a closed circuit.
So far, Porsche has kept the Taycan’s tire size secret. Even the camouflaged prototypes of the vehicle that have been deployed across the globe and spotted in numerous countries have mostly been equipped with unmarked tires. Fortunately, St00k, a moderator at TaycanEVForum.com, was recently able to capture a rare image one of the Taycan’s wheels that just happens to be marked.
What the TaycanEVForum.com moderator found was quite surprising. Looking at the Taycan prototypes that are being tested across the globe, it is easy to see that the all-electric vehicle is equipped with massive, wide tires.
As could be seen in the recently-shared photo, the Taycan prototype was equipped with 305/30/ZR21 Goodyear Eagle tires. That’s incredibly wide for a four-door sedan that’s the size of the Taycan, especially considering that the larger Tesla Model S P100D (now dubbed as the Model S Performance), only comes with 265/35/21 rear tires.
These large, wide tires hint at serious track performance for the Taycan. Large wheels such as 305/30/ZR21s, after all, provide exceptional handling for the upcoming all-electric car. This is particularly important for the Taycan, considering that one of its key selling points is its capability to be driven hard for extended periods of time without losing power.
So far, the Tesla Model 3 Performance is the benchmark when it comes to electric four-door sedans that can handle track driving, thanks to its dedicated Track Mode. With this in mind, Porsche would have to dig deep to make sure that the Taycan, which is significantly more expensive than the Model 3 Performance, will feature closed circuit driving capabilities that justify its Model S-level price.
While the Taycan’s 305/30/ZR21 tires confirm that the vehicle will be a monster around the track, the large tires also bring up some concerns about the vehicle’s range and efficiency. Larger, wider tires usually give optimum performance at the cost of range. This could be seen in the Model S, as a pre-“Raven” 100D equipped with 245/45/19 tires was listed with more range than a P100D fitted with 265/35/21 tires.
Hopefully, Porsche could balance the Taycan’s performance with its range well. This would allow the highly-anticipated vehicle to avoid the pitfalls of other premium EVs from European automakers such as Audi and Jaguar, both of whom have released otherwise great electric cars that are, unfortunately, the zero-emissions equivalent of gas-guzzlers.

The Boring Company’s latest Tesla tunnel truck mod “fits like a glove”
The Boring Company has modified a Tesla powered tunnel truck to carry freight containers underground.
The Boring Company has found a second job for the Tesla hardware it already runs underground. In a post on X, Elon Musk’s tunneling company showed its latest Prufrock Liner Truck modified to carry a standard 20 foot shipping container. “Using TBC tunnels to transport freight,” the company wrote. “The latest Prufrock Liner Truck (using Tesla Model 3 batteries and drive units) has been modified to carry a standard 20′ shipping container. Fits like a glove!”
The photo shows a red container sitting on a long, low white chassis parked outside, with drive hardware visible at one end. The Boring Company did not say where or when freight hauling would start, which customers it has in mind, or how many trucks it is converting.

Until now, the liner trucks have hauled concrete. Teslarati reported in August on Liner Truck 3, which uses Model 3 battery packs and drive units to move more than 22,000 pounds of precast tunnel segments to the boring machine. It has 28 miles of range, tops out at 12 mph, and is piloted remotely from the company’s operations center in Texas. The freight version appears to be the same platform with a different bed, and The Boring Company has not said whether it will also be remotely piloted.
Freight has been on the company’s menu for years. When TBC updated its product lineup in 2021, its freight tunnel was described as sized to fit a standard shipping container, “barely.” The company later used the idea at Tesla’s own factory, where Prufrock 3 dug a tunnel to Giga Texas that now moves finished Cybertrucks away from the production line.
The Boring Company closed a $3 billion Series D in September at a $23 billion valuation, and Teslarati has covered how that money is tied to a UAE tunneling push and a faster Nashville build. In Nashville, Prufrock MB1 and MB2 are mining at the same time, and a third machine is expected to launch in late October. Each machine needs a steady supply of liner trucks, so any design that works for segments and containers alike gives the company more use out of the same Tesla parts.
The Vegas Loop remains the only Boring Company system open to the public, and it moves passengers in Tesla vehicles. A freight service would be a separate product, and the post gave no indication that one is close to launch. For now, it is a truck, a container and a short caption saying they fit together.
Elon Musk said he is planning to give “every one of his SpaceX shares to every kid in America” in 2027, stating that “this will be the first of many.”
SpaceX went public earlier this year, and its stock price has been relatively stable since leveling off shortly after its IPO. Based on its current price, it’s a gift of just over $10 billion to children across the United States.
It appears to be closely related to President Donald Trump’s bank accounts for children, which were set up earlier this year as Trump Accounts.
Just hours earlier, Anthropic had announced the establishment of its Anthropic Public Benefit Fund, “a new wholly-owned entity dedicated entirely to public benefit.” Musk responded by stating he recommended “giving the shares directly to the public,” and that he would be doing it that way.
Just a little bit later, Musk said children across the U.S. would be getting a share from him:
Next year, I will give one of my SpaceX shares to every kid in America.
This will be the first of many.

There are roughly 70 million children, meaning someone under the age of 18, in the United States, according to the Federal Interagency Forum on Child and Family Statistics. Musk’s ownership of SpaceX stock shows he has around 849 million Class A shares of SpaceX stock, according to filings with the SEC.
Elon Musk revealed in a post on X that “Permits were impossible to get,” explaining the fate of The Boring Company’s most ambitious East Coast proposal.
The comment responded to a query about what became of his July 20, 2017 announcement that he had “just received verbal govt approval” for an underground Hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, D.C., capable of carrying passengers from the Big Apple to the Nation’s Capital in just 29 minutes.

The 2017 post, which envisioned city-center stations and multiple elevators in each city, sparked immediate scrutiny. Local and state officials in New York, Philadelphia, Baltimore, and D.C. said they had no knowledge of any approval. A White House spokesperson confirmed only “promising conversations” about the transformative infrastructure.
Musk clarified shortly after that there was “still a lot of work” to do for formal approvals.

Limited progress followed, as Maryland Governor Larry Hogan’s administration issued a conditional utility permit and supported work near Fort Meade. In 2018, Washington, D.C., granted a preliminary permit for site preparation and excavation on a vacant lot at 53 New York Ave. NE in the NoMa neighborhood, which The Boring Company said could become a station.
A draft environmental assessment for a D.C.-Baltimore segment was released in 2019. Yet, by April 2021, the company had removed the project from its website, and the Federal Highway Administration reported receiving no indication of further interest. Communication with Maryland officials had ceased.
The full corridor would have required coordination among the District of Columbia, Maryland, Pennsylvania, New York, the Federal Highway Administration, the Army Corps of Engineers, the National Park Service, and other agencies.
Environmental reviews under the National Environmental Policy Act, utility clearances, and approvals for novel infrastructure added to the overall complexity of the project and its approval.
Speculation on the permitting barriers centers around a few factors, but a multi-state, multi-level route involving unproven high-speed vacuum-tube technology inherently triggers exhaustive safety, environmental, and engineering reviews that can stretch for years, even for conventional projects.
There are also other elements, of course, like officials who may face political exposure if a privately funded, untested system encountered anything such as cost overruns, delays, or safety issues. On the outset of this project, there were limited things such as engineering plans or demonstrated technology maturity, which also added to the potential skepticism.
The East Coast vision for Boring Co., once framed as a privately funded revolution that could reshape Northeast travel, quietly ended without construction of the promised network. Musk’s recent statement frames the outcome as a regulatory impasse, unfortunate but not unexpected.
