Tread configuration of pneumatic tires for motor vehicles

Claim 1

A tread configuration with an axial direction and a circumferential direction for pneumatic vehicle tires especially spare tires to be used temporarily, consisting of in combination: transverse webs having a width, circumferential webs with a circumferential dimension, and a large number of substantially rectangular depressions having a long side located along the axial direction of the tire, said depressions being successively arranged in both the axial and circumferential directions of the tire, said depressions being respectively separated from one another by successive transverse webs and circumferential webs, the width of said webs corresponding to approximately 1/4 to 3/4 of the circumferential dimension of said depressions, said circumferential webs in pairs being offset relative to each other without any circumferential rows thereof being provided though sequentially following each other in offset relationship so that the tread configuration causes a loud noise to be generated as a constant reminder for necessity of changing the tire which is not intended for continuous operation, especially not for high speeds.
