All I see is a gimmick. These will not hold up on any type of large vehicle. There will always be a need for air filled tires. These will not be a huge game-changer. Minor at best for EVs and low mileage drivers at best. You will still have premature replacements with these because a lot of people do not do proper maintenance on their cars (alignment, struts, joints, etc). Nothing to see here but fancy dreams without true real world thought put into it.
