Tyre makers Bridgestone have unveiled a new tyre they have created that requires no air inside to make it functional. The new airless tyres are instead equipped with resin spokes inside the tyre that provide support for the load of the vehicle.
The new resin spoke technology does not run from the inner circumference (rim) of the tyre to the outer circumference (tread) in a radial pattern. Instead, as pictured below the angle of each spoke on the inner circumference of the tyre is about 45° different from that on the outer circumference, to provide extra support.
Also because the new tyre design uses both dextral and sinistral spokes, the forces that deforms the tyre tread does not become a turning force. The aireless tyre also enables drivers to continue even if the outer skin of the tyre is punctured. The new tyre is also created from recycled rubber and plastics, and can be recycled again after use.
The new Bridgestone airless tyre technology, is going to be showcased at the 2011 Tokyo Motor Show, which runs from December 3-11.
