Bridgestone says its ""˜Air Free' concept tyre could make production in less than two years, after undergoing testing on ultra-light vehicles.

<div style="line-height: 16.7999992370605px; : rgb251, 251, 253;">As the name suggests, the concept is a non-pneumatic tyre and consists of three main parts: an aluminium inner wheel, a rubber-based outer tread and thermoplastic resin spokes. The interlaced structure of the spokes helps the concept behave like a conventional tyre, supposedly offering the same level of manoeuvrability and stability.

<div style="line-height: 16.7999992370605px; : rgb251, 251, 253;">""˜One of the key benefits of the concept is that there's no need to worry about punctures,' says Bridgestone's consumer sales and marketing director, Farrell Dolan. ""˜There's also no need to check tyre pressures.'

Er., how could it
accommodate the difference in rolling diameter/response between
driver only, and a family of five going on holiday with a full boot
of luggage and a top box.
Either it would need to be so resilient
it never changed diameter (? hard ride) or it became increasingly
stiff depending on load (technologically very difficult), or maybe I have
totally misunderstood what Bridgestone are saying.Geri
