The Polaris Defense Non-Pneumatic Tire doesn’t go flat. It makes a great companion for their MRZR 2 & 4 all terrain vehicles.

This concept has been out in the wild for decades, but no one has yet to buy into it. Probably something nice and political involved.
Not sure if this would do well in sandy conditions, you can’t air down for extra floatation either…
Waiting for such thing in 26″ bicycle size. Would help a lot with innertube issues.
my only concern with this design is turning at high speeds. It would seem just from the pics that there would be a moderate amount of side to side shifting in a tight turn.
Actually, the advantage of these sorts of tyres over traditional pneumatic tyres is that they can be engineered to have great traction and road holding (like a tyre with low air pressure) while having minimal sidewall flex (like a tyre with high air pressure), so you get the best of both worlds.
The main reason that they haven’t caught on is that they typically suffer from heat buildup problems and transmit a significant amount of road-noise. As far as I know, the only ones commercially available are small and are suited to things like trolley trucks and ATVs.
I look forward to the day when they are commercially available in decent sizes for road and military vehicles.
I’m pretty certain that I’ve seen these types of wheels before on things like forklifts and the like.
Yea I’ve seen them too, but like you always on industrial vehicles that don’t travel fast.
