The aqua angled sides with variable groove wall are aligned in such a way that enough water can always be picked up even when there is pressure on the tread.

The increased length and thickness of the edges of the MS plus 66 provides for increased traction in the snow.
The MS plus 66 in detail
High level of aquaplaning safety –
even in winter
Today, winter weather brings more slush and rain than compacted snow and black ice. The MS Plus 66 is perfect for these conditions. The new 3D aqua-groove technology enables increased volumes of water to be collected in the tread and effectively prevents water building up in front of the tyre. The result: A high level of aquaplaning safety.
Outstanding traction and cornering control on snow-covered roads
In comparison with its predecessor, the MS Plus 55, the MS Plus 66 offers an improved grip on snowy roads and increased cornering forces in the snow. To this end, the gripping edges in the ground contact patch have been extended by 12 percent.
Long tyre life
The MS plus 66 remains flexible for its entire service life. This is rendered possible by new, non-migratory plasticizers, which are retained in the rubber compound even at low temperatures.
