The Goodyear UltraGrip Ice Navi NH winter tire was created with the specific climatic conditions of the country of the rising sun in mind. Like its predecessor, it is distinguished by its effectiveness when slowing down and maneuvering on icy surfaces. And it is precisely these properties that have been significantly improved in this model.
Increased blocks in the central part
One of the distinctive features of the tread is the enlarged blocks in the central part. These elements have high resistance to deformation, which, combined with their increased contact area with the road surface, improves directional stability on dry surfaces. The long transverse gripping edges formed by the blocks contribute to more effective tread operation when slowing down.
Zigzag transverse grooves
It is worth noting the unusual zigzag shape of the transverse drainage grooves. This expands the functionality of these elements, which contribute to better stability during longitudinal accelerations on snowy surfaces.
Resistance to aquaplaning and slash-planning
The main function of the above-mentioned transverse grooves is to divert water, snow, and their mixture with road dirt from the contact patch. Like the longitudinal elements, they have an increased width and depth, thanks to which the tire demonstrates high resistance to aquaplaning and slash-planning.
3D-lamellas
Compared to the previous model, the number of gripping edges has been increased by 13%. The bulk of this increase is provided by numerous lamellas, which are located significantly denser. This significantly enhances the grip properties on rolled snow and icy surfaces. At the same time, manageability remains comfortable due to the three-dimensional structure of the side walls of the lamellas. When in contact with the road surface, they fix the slit in the open position, limiting the mobility of the block. Here it is worth noting the different direction of these elements. On the very edge of the shoulder blocks, there are longitudinal lamellas. When maneuvering, they enhance the stability of the tire on icy surfaces.
Optimized contact patch shape
Another important difference from the previous model is the shape of the contact patch. It has been optimized to increase the evenness of the external load distribution over it. For these purposes, the frame design has been significantly strengthened, and the tread profile in the side projection has been changed. As a result, the stability of the grip properties has increased, and wear has decreased.
Main features:
- increased blocks in the central part increase stability and directional stability at high speed;
- zigzag transverse drainage grooves enhance grip during longitudinal acceleration;
- increased density of lamella arrangement compared to the previous model;
- optimized contact patch shape improves handling, reduces wear.
