Scientists unveil 'self-changing tyres'

The researchers at Leipzig university are developing the world's first-ever "intelligent" tyre which automatically adapts itself to the prevailing weather conditions even while you are driving.

A team of researchers headed by Detlef Riemer at the University of Applied Sciences in Leipzig unveiled the "adaptive tyre" at this year's Hannover Fair, the world's biggest industrial fair taking place in the north German city this week.

"Today's choice of tyres are always a compromise between the ability to brake and petrol consumption," Riemer said. "The car driver has to take into consideration every sort of weather condition and you can't change tyres while you're driving."

But Riemer's "adaptive tyre" is equipped with electronic sensors which recognise different sorts of terrain - whether motorway or dirt roads - and whether it's dry, raining or snowing.

And accordingly, the tyres' profiles are automatically raised or widened, even when the car is in motion. "That means your car is always equipped with the best possible tyre and noise and petrol consumption are automatically optimised, too," Riemer enthused.

"The driver no longer has to think about adapting their tyres. The tyre itself 'thinks' too."

The tyre is still a long way from a finished product and research is still ongoing, notably on the materials that can be used for the moveable parts of the tyre's profiles.

"But we've patented it already, just in case," Riemer said.

First, even if they sold this tire....it'd likely run around 1k Euro per tire. Second, the government would require five years of testing before they'd agree that this could replace the current summer/winter tire concept. Finally, you'd likely have to have a computer geek changing you over to this concept of tire....paying him 400 Euro for three hours of changing and hooking up the computer system to run the tires.

A real adaptive tyre is a one which should change its atomic structure depending on the temperature and humidity. In this case only the profile changes by moving parts mechanically, but not the structure of the tyre. So, this will not be a real replacement for winter and summer tyres, and the cost will be large. So, I think this will not come to production. Or maybe used in some expensive cars only.

Tread carefully fellow posters, you could be just getting the run around with this story!

Every big technological step requires a lot of time. Of course this will not be the direct replacement of having to change tires every season. But is the precedent to develop future technologies that in the future certainly will.

The self-changing tyre is really amazing. Though the tyre is still not yet accomplished, it has been already patented.It is very wise to do so because the law can protect the exclusive use of the tyre.Nowadays,patents are of vital importance in business.It is said that the Schaeffler Group registered 1832 patents in 2011 alone.
