Yokohama Avid ENVigor 255/55 R18 109V

According to representatives of the Japanese manufacturer, Yokohama Avid ENVigor is a tire "for almost everyone". This model is offered in over 70 sizes, some of which are designed for powerful sports sedans and coupes, as well as for SUVs and crossovers. Another feature of this tire is that it is positioned by the manufacturer as "all-season". This statement should be taken into account only when living in an area where winter is characterized by positive temperatures and lack of snow cover. Considering our climatic conditions, this model can be considered exclusively as a summer tire.

"Grooves in grooves"

The development of this tire used a large number of advanced technologies. One of these solutions is groove-in-groove. This term hides special depressions in the drainage grooves adjacent to the central longitudinal rib. These tread elements perform several functions at once. First of all, it is the direction of water flows from the longitudinal drainage grooves into the transverse channels, through which it is removed beyond the tread, which has a positive effect on resistance to aquaplaning.

Another function performed by the "grooves in grooves" is the improvement of directional stability and responsiveness to steering wheel turns. These properties are provided due to the increased stiffness of all three longitudinal ribs located in the central part of the tread to dynamic deformation. Thanks to the original configuration of the drainage grooves, these elements in the side projection have a conical shape, limiting their mobility, first of all, in the transverse direction.

Exceptional stability when cornering

The excellent stability in corners demonstrated by this model is ensured by the rigid construction and massive size of not only the central longitudinal rib but also the shoulder areas. But at the same time, they are characterized by a more open design, which is due to the need to provide traction not only when maneuvering but also when moving in other modes. In particular, when accelerating and braking. High efficiency in these modes of movement is achieved due to the presence in the shoulder areas of very wide blocks. They form a multitude of traction edges, each of which is distinguished by a significant length. In combination with the rigid construction of the shoulder blocks, this feature not only reduces the braking distance but also gives the traction properties stability and predictability.

Unique tread profile

A significant part of the numerous advantages of the Yokohama Avid ENVigor tire is provided due to the shape of the tread profile. When developing it, modern computer modeling technologies were used, as a result of which it was possible not only to maximize the size of the contact patch but also to ensure the preservation of all its characteristics in any mode of movement, regardless of the characteristics of the road surface. I.e., it remains unchanged, both in size and in shape (close to square), even with strong lateral accelerations. At the same time, the tire demonstrates very reliable and predictable handling, avoiding a sharp skid until the last moment.

Key features of Yokohama Avid ENVigor

- "groove-in-groove" technology increases resistance to aquaplaning, improves directional stability, and makes the tire's reactions even faster and more accurate;
- the rigid construction of the shoulder areas and the central longitudinal rib allows the tire to maintain stability at any speed, as well as provides absolute control over the trajectory of the vehicle's movement;
- the optimized tread profile shape improves handling, making it reliable and predictable, and also reduces rolling resistance and heat generation when driving at high speeds.
