ça sent le poisson d'Avril c'est pourtant pas l'époque

Si jamais c'est au point, super, adieu les crevaisons .

Je voudrais bien voir à l'accélération, si les rayons plient

Beau scoop en tout cas .

Je découvre ce sujet.
J'ai cherché un peu sur le net : c'est pas encore au point. Un extrait de Wikipedia in English :
"Benefits and drawbacks
Potential benefits of the Tweel include the obvious safety and convenience of never having flat tires. Eventually, it may be able to outperform a pneumatic tire since it can be designed to have high lateral strength for better handling without a loss in comfort since the design of the spokes allows the vertical and lateral stiffness to be tuned independently. The tread patterns may incorporate holes in the design thus eliminating or significantly reducing aquaplaning. Because only the tread around the circumference would be disposed of when worn as opposed to a whole tire, the environmental impact should be less.

The Tweel does have several flaws, however, the worst being vibration. Above 50 mph (80 km/h), the Tweel vibrates considerably, which in itself is a problem that also gives rise to undesired noise and heat. A fast-moving Tweel is unpleasantly loud.[2] The Tweel can also withstand a police 'stinger' spike strip, which would force law enforcement to adapt in order to stop a suspect in a vehicle equipped with Tweels."

Avantages : sécurité, fiabilité (pas de crevaisons), confort modulable, plus écologique.
Inconvénients :
- à partir de 80 km/h, fortes vibrations, s'accompagnant de bruit important et de chaleur.
- ne peut pas être arrêté par les plaques à clous des forces de police !!!
