New Airless Tires Coming "NASA" "Titanium" "Eco-Conscious"

Anytime a company uses "NASA" and "titanium" in its marketing beware,
but yet another airless tire design is coming soon.

Still, there's probably a market for such tires for bike-share bikes,
many of which use pretty terrible airless tires. I was riding a
bike-share bike in Vienna and thought I was getting a flat tire and was
looking for the problem until I saw that there was no valve. It was
terrible ride quality with whatever they were using.

Personally, for my non-road bikes, I have switched to Schwalbe Marathon
tires which are pretty much puncture proof, a trade-off for their
greater weight, and I don't see a need for NASA inspired airless tires.

In 2017 I rode some of those Vienna bikes, and I think they had Schwalbe
Marathon tires. The bikes were definitely heavy and sluggish, but did the job
of getting around town. I remember it cost one euro to register, and bikes were
then free for one hour at a time.

The Martian rover neither carries the load nor puts on the miles to wear these tires out. They do NOT have traction at the sorts of speeds a bicycle travels nor do they have a wear life even remotely related to a rubber tire that has been 200 years in development.

The one I rented in 2019 had tires filled with some kind of solid
material. I took it on a ride on Danube Island, the artificial island in
the middle of the Danube. It was still fun though it was so slow and
heavy that I couldn't ride as far as I wanted to.
