I wonder how well they will perform packed with ice and snow.

ToddinTN · 06-06-2019, 09:27 PM

Given some of the opportunities they have had with the tweets in OPE applications, it will be interesting on how they perform in automotive situations

Jeez...how much longer do we have to wait? Ive been seeing these things since i graduated highschool in 2007.

Silico91 · 06-07-2019, 05:19 AM

Pretty cool video considering its about a tire.

Wolf 335 · 06-07-2019, 08:50 AM

OK put a sidewall on it and lets get this out already! Its only been 10 years since it came out.

kring · 06-07-2019, 09:16 AM

Patience! we need to watch it roll over uneven pavement @ 7mph a thousand more times, that could take another 10-12 more years before it's ready.

I can just see it... every 10 miles some other driver will pull up along side you frantically pointing at your tires like something is wrong.

Last time I checked, rubber is heavier than air. It looks like the rubber support structure takes up about 80% of the tire's air space. They'll add some serious unsprung weight.

Yes, but look at all the air you'd be saving.

Humdizzle · 06-07-2019, 11:19 AM

Hopefully it wont be heavier than current tires.

It would be so nice to never have to see my TPMS light every time the seasons change.

And with more resistance

Some military vehicule have been using a similar technology since the 60s already.

In term of weight, you exchange the sidewall for these inner ribs. Looks like the ribs are going to be heavier, but maybe not that much more so given that the sidewall must be steel-belt reinforced to endure the abuse of lateral flexing in corners.

I suspect it will ride very similarly to crappy Bridgestone run flats.

Shh, or BMW will order ten million of them.

What pressures do you guys think these should be run at for Autocross or Track days?

I'd suggest one bar.

Along the lines I was thinking too, although I was closer to 800 mmHg.

Seriously though, I wonder how these would react to turning and cornering forces, the shoulder seems so small. I would imagine that the side of the tire might end up folding onto itself and collapsing with hard cornering/turning forces.

Do you think the video is any indication that these are meant for Chevy Bolts doing 7mph through wide corners.

No, they were designed for the i3, but it ran short in testing...

ScottyRyan2019 · 06-08-2019, 09:40 AM

Let me see, when is the last time I had a flat or a tire failure? Oh yeah, like I think Reagan was president. I will stick with air in my tires, Bob.

SSBMW14 · 06-23-2019, 05:24 AM

Interesting development in the tyre space - have seen something similar a few years ago for construction/farming use, but this is quite significant I think for cars if it comes to being.
