The days of flat tires and spares are numbered. Sure, self-inflating tires are all well and good, but don't protect from the darn puncture itself. Similar to Michelin's tweels, Bridgestone has cooked up some air-free concept tires that use a tough but flexible thermoplastic structure that behaves like a normal tire with nary any horizontal force produced. Each wheel is able to support around 150kg, although on a typical electric mobility scooter the load is more likely to approach 50kg. Bridgestone is looking to show off those curved, hypnotic spokes on the retail model, but is still researching how to protect against objects getting lodged inside. Roll over the break to see those spokes in action and imagine a future without puncture repair kits.
