Among the new winter / snow tires available this season is Dunlop's Winter Maxx. Positioned in the popular Studless Ice & Snow category, the Winter Maxx has been very competitive in our testing against the current leaders in the category, the Bridgestone Blizzak WS70 and Michelin X-Ice Xi3.
On the road, they were more stable and responsive than the Graspic DS-3 that they replaced, and on the ice rink they were some of the best in this year's testing. Test results will be published later this month, so stay tuned.
At the left you can see a photograph of the Winter Maxx's tread pattern. Typical elements like angled tread blocks, plenty of void area and horizontal biting edges are present.
In addition, Dunlop has made extensive use of siping for the Winter Maxx. Note how nearly the entire face of the tire is covered with tiny serrated-looking lines. Those small cuts in the treads are called sipes.
By using interlocking zig-zag sipes, Dunlop is able to pack in a very high density of siping without unduly compromising the tread-block stability required for stable, consistent road handling. Each sipe provides additional edges when the tire is trying to 'bite' into the snow to provide traction. But when subjected to cornering loads, the sipes interlock, acting like a solid tread block and providing a more stable feel when cornering than a tire with such heavy siping would usually offer.
The sipes work in combination with the rest of the tread design and the specialized winter compound to create a top-notch winter performer. For more detailed information about the Winter Maxx, and to shop for available sizes, view here.
