<p>The invention is based on a pneumatic vehicle tyre constructed as a radial tyre which has on both sides of its tread widened portions which are formed by stepping and do not come into contact with the road surface. In order to achieve a reduction of the resistance to rolling in a tyre of this design and to obtain an homogeneous wear pattern, the edges of the belt project beyond the perpendicular step faces of the extended portion by an amount which is approximately 25 to 40% of the amount by which the bevelled-out tyre side walls project beyond the perpendicular step face at its widest point. <IMAGE></p> |
