Abstract
A tire has a curved tire surface and a nano-scale structure disposed on a portion of the curved tire surface. A contact patch on the curved tire surface contacts a contact surface as the tire rolls along the contact surface. The nano-scale structure has a base and a tip. The base is connected to the portion of the curved tire surface. The tip is disposed opposite the base. When the portion of the curved tire surface with the nano-scale structure is positioned away from the contact patch, the nano-scale structure is in a relaxed position. When the portion of the curved tire surface is rotated into the contact patch, the nano-scale structure is engaged with the contact surface. When the portion of the curved tire surface is rotated through the contact patch, the nano-scale structure is adhesively anchored to the contact surface with the nano-scale structure undergoing tension and compression. When the portion of the curved tire surface is rotated through the contact patch to leave the contact patch, the nano-scale structure is released from the contact surface as an angle between the base and tip surpasses a release angle for the nano-scale structure.
