I don't quite get the purpose of that bike tire. Tubeless tires are basically puncture proof aswell. I'd imagine that much metal just makes it unecessarily heavy.
Where do you get that from? Vehicle tires are all tubeless, they are far from puncture proof.
Tubeless bicycle tires are often used with slime as otherwise they tend to leak from the edge of the rim as the pressure isn't usually high enough to create a perfect seal. That also means they are effectively "self-healing" and puncture proof. Also tires that have this strip of goopy glue like stuff on the inside that seals all by itself are starting to get rather common as well.
The tire sealant that is used inside tubeless bike tires seals small holes by itself. Driving over a nail is not going to be an issue.
Puncture resistant, not puncture proof. Tubeless sets with sealant can take multiple punctures before losing too much air ans/or sealant.
Also larger punctures don't get sealed by the sealant alone, but you need to fill the hole with something like rubber plugs
Puncture proof would mean that they can't be punctured or that puncture had zero effect
They keep calling it lightweight but aren’t saying what that weight is. It’s gotta be in the ballpark of a rubber tire to really be viable, so I’d say 4lbs at the absolute top end. More than that and it may reduce rolling resistance while shooting itself in the foot with the added rotational mass.
