A further object is to provide a type of tire which will permit control of an automobile over rough roads at higher speeds than are possible with inflated tires and a still further object is to provide a comparatively cool tire at high speeds. Still further objects are to provide a flexible type of tire for climbing curbs or tracks at small angles and to hold and conform to the road while delivering less violence to the axles over bumps in the road.

You can round the contact surface a bit or design the wheel with steps.<br />The small road driving surface would sink into soft soil and the other wheel surfaces would come into contact with the soil.S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-43597945317270912942011-06-10T13:17:26.003+02:002011-06-10T13:17:26.003+02:00Interesting stuff Sven, the Resilient Technologies...Interesting stuff Sven, the Resilient Technologies website is still active, I wonder how close they are to production of a workable solution<br /><br />http://www.resilienttech.com/<br /><br />A lot of the modern vehicles now use variable tyre inflation systems to adjust ground pressure and improve off road mobility or on road speed, how would the airless tyre deliver a similar variable footprint?think defencehttp://www.thinkdefence.co.uknoreply@blogger.com
