PNEUMATIC TYRE, AND WHEEL STRUCTURE OR VEHICLE DRIVE FORMED THEREOF

摘要

A pneumatic tyre (11) for use together with an emergency-driving device (15) and/or a track (30) has a rubber layer (20, 32) of low-friction properties and a high wear resistance, at least in surface areas which in use come into contact with the emergency-driving device (15) of tyre-supporting elements (31) on the track (30). The low-friction rubber employed is butadiene rubber, optionally with a minor addition of natural rubber and/or styrene-butadiene rubber in an amount less than 50 % of the polymer material.
