The excellent operational qualities of the Hankook AH22 truck tire are evidenced by the fact that the South Korean manufacturer has developed a new model based on it, borrowing not only the main technical solutions but also the name. Another confirmation of the uniqueness of this tire is its presence in free sale for many years, during which it has proven itself from the best side.
Excellent applicability
One of the factors of the tire's longevity is its unusually wide range of applications. The successfully selected size range and universal tread pattern have made it applicable to any modern truck or bus, where it can be operated on any axle throughout the year.
Universal tread pattern
This model is equipped with a symmetrical non-directional tread pattern, the design of which is perfectly optimized for use on both the steering and driving axles of a truck or bus. Due to this, the tire demonstrates excellent directional stability at any speed, low rolling resistance, excellent traction in any weather conditions, and a very long service life.
Excellent traction on dry and wet roads
The central part of the tread pattern of the Hankook AH22 model is occupied by three longitudinal ribs of equal size. Each of them contains a multitude of straight lamellas, which, when in contact with the road surface, form very long transverse zigzag-shaped traction edges. At the same time, the lamellas are cut through the entire depth of the tread, thanks to which the tire retains its initial traction properties throughout its entire service life.
It is also worth noting the presence of a very efficient drainage system, the effectiveness of which is ensured by four longitudinal grooves. Their volume is quite sufficient to remove even a very significant amount of water from the tread, thereby keeping the contact patch dry. At the same time, there are special stone ejectors at the bottom of the grooves, which do not allow the tread pattern to become clogged with stones and other solid foreign objects.
Low rolling resistance and long service life
During the development of this model, great importance was attached to the indicators of durability and rolling resistance. They were able to make them very high due to a number of changes in the design of the carcass, sidewalls, and tread pattern.
The carcass design has been significantly strengthened due to the breaker layer, which has been significantly increased in size, allowing for the creation of a very rigid base for the tread. As a result, it has become much better at resisting dynamic deformation that occurs during movement. With similar goals, the deformability of the sidewalls has been increased, which, due to their strengthening, have become much more rigid.
In addition, it is worth noting the design of the shoulder areas, each of which is a very wide longitudinal rib with very high stiffness due to the absence of any breaks throughout its length. The combination of massive dimensions, high resistance to deformation, and a low-radius profile has made it possible to distribute the external load over the contact patch much better. As a result, the tire's tread has become much more resistant to uneven wear, which has had a very favorable effect on the tire's durability.
Main features of the Hankook AH22 truck tire
- wide applicability, expressed in the possibility of year-round operation on any axles of not only trucks but also buses;
- low rolling resistance and excellent directional stability, thanks to five very wide and rigid longitudinal ribs;
- excellent traction properties and braking efficiency throughout the tire's service life, ensured by numerous straight lamellas in the central part of the tread, cut through its entire depth;
- long service life due to special components in the rubber mixture and the company's proprietary technology for its preparation, as well as the strengthened design of the shoulder areas, which ensured a more even distribution of the external load, which, in turn, led to a reduction in the likelihood of uneven wear.
