CLAIMS

What we claim Is:

1 . A multi-purpose tire comprising:

a tread section comprising a main tread zone and at least one auxiliary tread zone,

the tread section is configured to facilitate, at a first inflation pressure, a first tread configuration, wherein the at least one auxiliary tread section makes contact with a road surface and, at a second inflation pressure, a second tread configuration, wherein a contact of the at least one auxiliary tread section with the road is prevented or reduced, the first inflation pressure being lower than the second inflation pressure, wherein the tread section further comprises, in an inner surface thereof, one or more channels extending continuously in a circumferential direction of the tire and configured to regulate an inflation-pressure-dependent transition between the first and second tread configurations.

2. The tire of claim 1 , wherein the one or more channels form a joint structure facilitating the transition between the first and second tread configurations,

3. The tire of claim 1 , wherein the one or more channels at least partially contain a substance having elasticity higher than the elasticity of the inner surface.

4. The tire of claim 1 , wherein the one or more channels at least partially contain a substance having compressibility higher than the compressibility of the inner surface.

5. The tire of claim 1 , wherein the main tread zone is a central zone and the at least one auxiliary tread zones comprise two side zones located on both sides of the central zone.

8. The tire of claim 1 , wherein the first configuration facilitates full load driving mode and wherein the second configuration facilitates light weight driving mode.

7. The tire of claim 1 , wherein the main tread zone comprises a first outer surface characteristic and the at least one auxiliary comprises a second outer surface characteristic being different from the first outer surface characteristic.

8. The tire of claim 7, wherein the main tread section comprises a first outer surface pattern and the at least one auxiliary section comprises a second outer surface pattern being different from the first outer surface pattern.

9. The tire of claim 8, wherein the first outer surface pattern is configured to facilitate driving on a paved road and wherein the second outer surface pattern is configured to facilitate driving on "off road" conditions.

10. The fire of claim 8, wherein the first outer surface pattern is configured to facilitate driving on an essentially dry road and wherein the second outer surface pattern is configured to facilitate driving on a wet, icy and/or snow covered road.

1 1 . The tire of claim 7, wherein the second outer surface comprises studs configured to facilitate driving on an icy and/or snow covered road.

12. The tire of claim 1 , wherein the second tread configuration facilitates economy driving mode and wherein the first tread configuration facilitates high speed driving mode.

13. The fire of claim 1 , further comprises one or more reinforcing elements extending radially from the tire beads, along the side wall and around the tire, the one or more reinforcing elements are essentially perpendicular to the one or more circumferential channels, wherein the one or more reinforcing elements comprise indentations at locations fitting the one or more circumferential channels.

14. The tire of claim 13, wherein the one or more reinforcing elements comprise one or more metal cords.

15. A method of manufacturing a multi-purpose tire, the method comprising: utilizing a tire building machine (TB ) comprising a drum having one or more bulges at preselected location(s), applying one or more layer of tire production material on the drum such that the resulting tire will include a set of circumferential channels in an inner tread section thereof, wherein the locations of the circumferential channels correspond to the locations of the bulges on the drum.

16. The method of claim 13, wherein the tire production material comprises an inner liner, body plies or a combination thereof, wherein the set of circumferential channels are formed at least on the inner liner.
