Snow would be the primary "added" weight concern, in my opinion.

I don't think they are that stupid.

Most articles I've read have specified no sidewalls. I'm hoping that just means you're right in that there are no structural sidewalls, but the innards are still covered.


Looking at the basic design, the wheel's barrel will have to contact with the tire continuously, wouldn't it? I don't see the load-distribution working without a wheel in the center to press against. Curious to see if these are universal to wheels or wheel specific, meaning no aftermarket wheels.


I'm not sure what problem this tire is solving. No increase in tread life, no decrease in weight, no benefits that I can see aside from being a better solution for cars that no longer have spares. Obviously, if you're too stupid or ignorant to maintain air in your tires, these might be a better option for you, but beyond that, I don't get it.

These are just what you need for a get-away car. Presumably a cops spike strip won't work.

The almighty Google says there are 220 million flat tires in the US every year. Even if people have spares (an estimated third of new cars do not) and are competent enough to safely change it on the side of the road (a fraction of the public), I think the benefit is pretty obvious. Instead of stranding someone on the side of the road in the rain (or, in the case of a runflat tire, buying you X miles before you have to stop), this remains completely unaffected by a normal puncture--the driver may not even notice. No jacking the car up on a gravel shoulder as 18 wheelers go by at 70+ mph, no replacing a half-used tire (or all of them) because of a single poorly placed screw, no lost time in transit, less road debris for the rest of us...

It's probably not a benefit I personally am interested in--but I get it.

These tires will also fail if they hit hard road debris or big pot holes. It won't solve the problem but should reduce it.

I think the manufactures like them because they are maintenance free.

I'd love to know the percentage of tire failures that are caused by maintenance issues or neglect. I'm guessing it's a majority.
