the predetermined position where they are incorporated in fabric 13 the position of reinforcing elements 15 is stabilized by shaping the reinforcing elements 15 into metal straps and placing them side by side in fabric 13 as is illustrated in the partial cross section of fig6 in addition the position of the metal straps 15 is stabilized because each strap 15 lies perpendicular to the direction of the force from the air pressure inside tire 1 the position of each strap 15 is stabilized further because the width of strap 15 designated by the value u201c l u201d is at least 1 mm both of these characteristics improve the resistance of strap 15 to compression into the elastomeric material in which metal strap 15 is incorporated as explained above by way of a specific example of one embodiment of the present invention the width u201c l u201d of metal strap 15 may be 3 mm in cross section the thickness u201c s u201d of such a metal strap 15 would be 0 03 mm and the thickness u201c s u201d of the rubberized fabric incorporating the coils of metal strap 15 coils would be 0 3 mm distance u201c d u201d between the ends of the contiguous metal straps would be between 0 5 and 3 mm according to the present invention metal straps 15 are.
