Future Tires Widen Operating Conditions

Posted March 18, 2015 12:00 AM by Engineering360 eNewsletter

After an auto engine's power passes through the driveline, it is the task of the tires to put that power efficiently and safely to the road or ground. Winners of this year's Hankook Tire Design Challenge from the University of Design, Engineering and Business in Pforzheim, Germany, came up with innovative ways of operating a tire over a range of ground and weather conditions. First prize was the Dakar tire for on- and off-road driving. The tire is made of individual, inflatable hexagonal blocks that are positioned close together on pavement, and then spread apart on a special wheel for off-road traction.

How are the hex blocks spread apart?

"and then spread apart on a special wheel for off-road traction"

Can this be done from the passenger compartment?

For Dakar use the ability to alter such tyre on the run from inside the cockpit would be mandatory...a special wheel was mentioned somewhere.

How it works is a big secret according to the article. There were some other really interesting designs featured in that article too.

If you buy a set take one apart and let everybody here know how it works.

I liked the individual inflatable pockets/cells...modular is always good and so much redundancy. Throw away your jack.....
