Michelin's new Unique Puncture-Proof Tire System (Uptis) does away with one of the defining aspects of tires as we've known them for more than 100 years: the air inside. Unlike past attempts at airless tires, Uptis functions the way other modern tires do and, Michelin claims, will provide a similar driving experience.
Unveiled at the company's sustainable-mobility-focused Movin'On Summit in Montreal today, Uptis is a tire without a traditional sidewall that carries its load by the top thanks to a new resin-embedded fiberglass material that Michelin was granted over 50 patents for. "The idea was to develop a technology that was strong enough to carry the load but light enough to replace the air," Cyrille Roget, technical and scientific communication director for the Michelin Group, told Car and Driver. "If you have a load on the tire and you cut all the spokes at the bottom, you will see that nothing will change, demonstrating that the load is carried by the top of it, not by the under parts." Other airless tires, he said, often carry the load at the bottom of the tire, which is very inefficient and causes extra heating due to compression.
Uptis is not Michelin's first airless concept tire. It builds on the Vision concept that was introduced at the 2017 summit meeting. That concept had four main components: it was airless, connected, could be 3D printed (or have a rechargeable tread pattern), and was 100 percent sustainable. Uptis tackles the first of those problems as part of what Roget called a "step by step" process to the tire of the future. Michelin will test Uptis in the real world with General Motors. GM will outfit a fleet of its Chevrolet Bolt EV hatchbacks with the concept tires for

Was one of them named Clark Gable?
The sidewalls have been removed for demonstration. The thing that pops in my head is the “unsprung” weight of the tires. Tires that weigh 2 or 3 times more than conventional tires could really put a dent in fuel mileage.
“The couple spent an unplanned week in a remote area waiting for a new rim.”
That sounds like the beginning summary of a horror movie.
“World war 1 solid tires ?”
Nope.
Ugh!!!! Even if a few scenarios don’t work out for the tires, this is awesome!!!!!! You are the type that says, yes the economy and unemployment numbers are great, but what about that guy who is on life support? He can’t get a job.

Read the post.
My Big Wheel had airless tires...
Lol.
Those were the days...
Looks like they’d tbe great mud
and rock slingers.

Windshield replacement is the New “Plastics” (if these puppies catch on)

Sometimes it pays to read the article before posting.
“What happens if a medium sized rock gets wedged in the middle?”
First poster but doesn’t read the post he is posting to.
“Maybe they plan to cover the sidewalls on the final product and this is just to show how they work?”
No maybe.
“That makes it sound like it’s a wheel and tire in one assembly. Weird and sounds expensive as hell.”
Watch the first 10 seconds of the video.
“What happens if slush gets in there and freezes solid? Massive imbalance? “
They have an automated washer installed for slush.
Guess we’re gonna need new spike strips. How are the cops going to stop cars?
I did. I see no reference to tire weight. It did say lighter than the air it replaces but nothing on total weight. I know it doesn’t take much weight below the suspension to lower mileage or ride quality.
Please post a link for the
article you’re referencing.
All I see in this post is a
linked Youtube video.
Thank You.
