Tesla in Talks With Michelin To Test New Airless Tires (Michelin Says No)

Update: While our original story sources mentioned that Florent Menegaux had begun talks with Tesla to test its Uptis airless tires, Michelin has since reached out to us and denied this. We are leaving the story up with this update at the top, and providing various sources for our readers. The original article is intact below:

Michelin, one of the world’s largest tire manufacturers, recently confirmed in an interview with its CEO Florent Menegaux that it has begun talks about testing its Uptis airless tire technology on Tesla vehicles.

Michelin has so far been testing the Uptis tires on the Chevy Bolt and has also opened talks with GM for use on their EVs. So far, these tires are still all prototypes, so nothing for consumers just yet, but they could hit the market as early as the end of this year. Tesla has previously tested Goodyear’s airless tires in 2021.

Advantages of Uptis Tires

The Uptis (Unique Puncture-Proof Tire System) is a rather unique design that is airless, puncture-proof, and based on an open cell design.

Uptis essentially uses the strength of a unique composite, which has a rubber tread bonded to it. On the inner side of the tire is a network of flexible spokes that bend, and flex as required by road conditions and car weight.

When the tire rolls forward, it naturally flexes down and around small obstacles, providing far more flexibility than standard tires with air inside them. On top of that, they are uniquely puncture-proof, as there is no air to be lost if the tire rolls over a sharp object.

Michelin expects Uptis tires to last roughly 3 times longer than conventional tires, reducing tire waste and lowering emissions from tread wear. This will also help reduce the number of tires sent to scrapyards, contributing towards sustainable practices.

Advantages for Tesla

Uptis tires are also lighter and more aerodynamically efficient than regular tires – the open-cell design notwithstanding. Interestingly enough, many would think that the open cells would cause additional drag, but initial testing on EVs from Michelin has been “described as positive”.

If the tires truly do reduce drag, or at least cause similar amounts of drag to conventional tires, the reduced weight of airless tires could improve efficiency for EVs even further. This is a tire to watch if you’re interested in increasing your own Tesla’s range.

Menegaux also mentioned that these airless tires would likely be limited to “certain types of applications”, though he didn’t mention which application or why they’d be limited. It’s possible it could be limited to certain weather conditions or types of roads. They could possibly be a good fit for autonomous vehicles, like Tesla’s upcoming Robotaxi, which is set to be revealed on 8/8.

Tesla Increases Price of Model S; Starts Offering Free Lifetime Supercharging

Not a Tesla App

For the first time in quite a while, Tesla has increased the price of one of its vehicle offerings. The Model S Long Range and the Model S Plaid have both received a hefty price increase. However, not all is bad - as Tesla also added a new benefit for buyers.

Price Increase

The price increase for the Model S is $5,000 - currently only in the United States. This price increase will likely impact other markets, including Canada, in the coming days.

The Model S Long Range now starts at $79,990, while the Model S Plaid now starts at $94,990. The Model S and Model X now have the same starting price. Interestingly, that’s also the same pricing point for the Cybertruck AWD and Cyberbeast Trimotor non-Foundation Series. 

The vehicle configuration does not appear to have changed, so the new pricing is simply an increase rather than the addition or removal of features. Tesla previously cut the price of the Model S and Model X by 15% in 2023, so this could simply be an adjustment to ensure that the vehicle pricing stays in line with inflation and other factors.

Free Lifetime Supercharging

For those on the fence about ordering a Model S, Tesla has brought back Free Lifetime Supercharging when you order a new Model S on or after December 13, 2024. As always, Free Lifetime Supercharging is restricted to the buyer’s Tesla account and to that specific vehicle. It cannot be transferred to another vehicle or another owner after ownership transfer. It’s worth noting, that it also doesn’t exclude the owner from receiving Supercharger idle fees or congestion fees. There is currently no end date for this promotion.

There are currently no changes to the Model X, neither a price increase nor the addition of Lifetime Superchargering. However, when Tesla makes changes to one of their premium vehicles, it usually affects the other one as well. So be on the lookout for potential changes to the Model X offering in the coming days.

We’ve seen Tesla value Lifetime Supercharging at $5,000, so this falls in line with the price increase we’re seeing. It’s possible that Tesla will begin to bring back Lifetime Supercharging as a perk for buying into their more premium Model S and Model X cars, or this could be another temporary promotion to get buyers who are on the fence to go ahead and make their purchase while this promotion lasts.

Tesla’s Optimus Robot Learns to Walk Without Vision [VIDEO]

Optimus Falls - but catches itself!

Not a Tesla App

Tesla recently showed off a demo of Optimus, its humanoid robot, walking around in moderately challenging terrain—not on a flat surface but on dirt and slopes. These things can be difficult for a humanoid robot, especially during the training cycle.

A Look Behind the Curtain

Most interestingly, Milan Kovac, VP of Engineering for Optimus, clarified what it takes to get Optimus to this stage. Let’s break down what he said.

Optimus is Blind

Optimus is getting seriously good at walking now - it can keep its balance over uneven ground - even while walking blind. Tesla is currently using just the sensors, all powered by a neural net running on the embedded computer. 

Essentially, Tesla is building Optimus from the ground up, relying on as much additional data as possible while it trains vision. This is similar to how they train FSD on vehicles, using LiDAR rigs to validate the vision system’s accuracy. While Optimus doesn’t have LiDAR, it relies on all those other sensors on board, many of which will likely become simplified as vision takes over as the primary sensor.

Today, Optimus is walking blind, but it’s able to react almost instantly to changes in the terrain underneath it, even if it falls or slips. 

What’s Next?

Next up, Tesla AI will be adding vision to Optimus - helping complete the neural net. Remember, Optimus runs on the same overall AI stack as FSD - in fact, Optimus uses an FSD computer and an offshoot of the FSD stack for vision-based tasks.

Milan mentions they’re planning on adding vision to help the robot plan ahead and improve its walking gait. While the zombie shuffle is iconic and a little bit amusing, getting humanoid robots to walk like humans is actually difficult.

There’s plenty more, too - including better responsiveness to velocity and direction commands and learning to fall and stand back up. Falling while protecting yourself to minimize damage is something natural to humans - but not exactly natural to something like a robot. Training it to do so is essential in keeping the robot, the environment around it, and the people it is interacting with safe.

We’re excited to see what’s coming with Optimus next because it is already getting started in some fashion in Tesla’s factories.
