The invention relates to tread part- In the figures, 1 denotes the tire with the

pieces for the soling of coarse tires with outer radius 20, on the running stripe enteilteile 2 α

high profiles and extended side wall are applied in front with their abutment surfaces 19. Since the

molded and vulcanized state. Sections have a larger inner radius 21,

It is known that when retreading the barrel 5 they will always be centered 22 first on the Lay strips of several sections the width of the tire, and this avoids that To put together the running surface. It is also known that air bubbles remain under the sections 2 α, the tread from several adjacent in cross-section. Furthermore, the tread from a right to assemble arranged rings. Section 46 and a left section 47 or from These two and a middle section 48 are present in these known treads joined together all butt surfaces must be butted together. The levels of separation of these parts on the reverse that especially with heavy tires run easily-transversely, and perpendicular to the wheel axle 49. At Damage points occur on the joint surfaces. mirror images of the same pages are sufficient for production

The invention is based on the object of this one single shape. The common disadvantages of touch to eliminate and treads from partial areas of these parts are teeth 50, tenons, bolts to produce pieces whose abutment surfaces are also provided transverse 51 or similar parts, which are used in the "Aufkraft can take up without thereby a detachment of the tread interlock. Are good to cause the abutment surfaces. all connections in the direction of the division

For this purpose, according to the invention, predetermined acting forces will be able to absorb, that is

suggest that the tread sections are attached to the 20 interlocking projections and recesses that

can absorb common contact surfaces in longitudinal and transverse forces; this also includes

Transverse direction transverse forces absorbing teeth, approximately semicircular protrusions and recesses (FIG. 7) or

Latches, tenons, semicircular projections and recesses on both sides semicircular, recesses into which a ring

or semicircular recesses on both sides with a 55 are inserted. You can also do this in the longitudinal direction

Have insertable ring. 25 the contact surfaces should be separated and

This ensures that the abutting surfaces do not grip one another (FIG. 5). Through this, longitudinal division is can replace. The running time of such treads is also given the opportunity to use the running strip thereby increasing the image of different widths by placing between the
