Future Of Tyres Is Air-Less, Literally

 
It may look silly but the weird tires on this electric golf-cart might just be the wave of future. This is Bridgestone's concept of air-free tyres which unlike conventional tyres don't get punctured or need air top-up and can be fully recycled once tread is worn out.

In the video below, CNET reporter explains how these Bridgestone air-free concept tyres have thermoplastic spokes with a special curve that enables them to flex effectively without twisting. It definately looks to be a promising idea but still needs work to address concerns like vibrations, sagging, high speed stability and what about cleaning those thousand spokes.

Myths About Nitrogen Filled Tyres Busted: Video

 
Nitrogen vs Air Filled Tyres: Which is better? A lot of people believe that since nitrogen filled tyres are used in hi-tech products like space shuttles, aircrafts and race cars, so that makes them good for our modest automobiles as well.

Theoretically its correct but practically speaking, the nitrogen used in motor racing and other extreme applications is completely dry, meaning it has 0% humidity and such quality nitrogen can't be made available at local dealerships. So what we get instead is nitrogen with traces of water vapor which completely diminishes any benefits that we hoped to achieve except for less loss of air pressure over time.

In the video below, the guys at Fifth Gear drive and compare two identical Suzuki Swift, with tyres of one filled with compressed air and other with nitrogen in an attempt to find the truth behind the myth.
