Normal pneumatic tyres can be run at higher pressure to compensate for increased load, even between the front and rear of the car.
Can these compensate for increased load?
If not, how are these practical for everyday use where you might drive alone, or with four passengers, on the same day.
In the same vein, would each model car only use a tyre made for that car?
What happens if I want to run wider or taller tyres, or maybe I'd want to run fancy mags.
I think these are a great concept, but like many concept cars, maybe it's just not practical.
... or am I missing something?
