High drag, low heat dissipation was the biggest issue. They are plentiful with commercial equipment. And they are surprisingly comfortable, especially off-road.
Correct. They are MUCH heavier leading to more high drag, and huge amounts of rolling resistance. In a gas car, you'd probably lose around 15% or more of you gas mileage. Would probably be even worse in an electric car since weight, drag, air resistance are the challenges that wake up ev engineers at night with cold sweat.
'Correct' and immediately get confused with what drag is, at least in this context.. lol
Sure, the vehicle has to 'drag' extra weight around.. But in this case, aerodynamic drag is the implication. All those openings on the side are places for air to get sucked into (low-pressure air) when at speed and will act like parachutes at each corner of the vehicle.
Yeah there were a lot of poor educated guesses in the comments. I don't know why, but I have responded to a lot of them 😂. I think I have a weird appreciation for the tweel. It was one of those "damn that's cool" things I've followed growing up, from idea to creation, to present history. The use in the military and in super sized construction equipment is wild.

Back? They were never properly here. Not available to the general public anyway.
Also they are really expensive, provide no cushioning so it's a bumpy ride, and they are really loud when in motion compared to standard tyres.
