摘要:
A pneumatic tire (10) is disclosed comprising a tread (12) and a belt package (50) located radially inward of the tread (12). The belt package (50) includes a pair of working belts (54, 56), wherein the working belts (54, 56) are reinforced plies each comprising parallel reinforcement elements, wherein the angle of the reinforcement elements in the respective working belt (54, 56) is in a range of from 12 degrees to 35 degrees with respect to the circumferential direction. The belt package (50) includes a further belt (58) positioned between the working belts (54, 56), said further belt (58) comprising parallel reinforcement elements angled in a range of from 5 degrees to 0 degree with respect to the circumferential direction. Finally, there is a split belt formed of a first split belt structure and second split belt structure (62), wherein the first and second split belt structure (62) are each positioned radially inward of an axially outermost groove (36) on each side of the tread (12) and each extend at least partially below said axially outermost groove (36) on each side of the tread (12).
