Beschreibung
Zusammenfassung:	A pneumatic tyre (100) for forestry use, comprising a ground-engaging tread section (10) including a series of secondary tread blocks (24), each secondary tread block (24) being in a tread groove (38) between two consecutive primary tread blocks (20). The secondary tread block (24) extends radially from a tread groove bottom (22) to a height (H2) that is reduced with respect to the height (H1) of the radially outermost surfaces of the primary tread blocks (20). A radially outermost surface (26) of the secondary tread block (24) provides a protecting surface adapted to safeguard the tread groove bottom (22) from a track (200) to be placed on the tread section and a shoulder surface (28) of the secondary tread block (24) provides on a side of the tread section (10) a supporting surface adapted to support the track. An end of the secondary tread block may form a step (30) adapted to support a tyre chain (500) to be placed on the tread section.
