Nokian Hakkapeliitta 4 - safe and "tenacious" winter tire. The secret of success: square stud and canola oil.
In the design of the studded tire Nokian Tyres to the team was quite clear goal: to develop a safe tire that is equally reliable behavior in all weather conditions from autumn to spring. To improve the coupling properties have been found worthy of creative solutions. Nokian Hakkapeliitta 4, called full-blooded winter tire has their ability to resist sliding, thanks to a four-sided spike. Eco-friendly and have excellent traction tire also makes canola oil. Nokian Hakkapeliitta 4 is designed for consumers Nordic and Central Europe.
Square stud enhances grip properties.
Properties of good studded tires are made up of a combination of properties and tire spikes. In the development of Nokian Hakkapeliitta 4 very carefully perfected spike. In the course of the Nordic countries, extensive testing concluded that the square stud keeps well, and is strong in the tire more stable than conventional round or oval spike. Through the use of a new thorn for Nokian Tyres test results have improved traction on ice by about 8%. The new tire is compared to its predecessor Nokian Hakkapeliitta 2.
Carbide rod and flange new spike is rectangular in shape. New aluminum spike is larger than its counterparts, and firmly seated on the bus. Angularity of carbide rod spine improves grip on ice. Thanks to the new form and structure of the spike protector driver can better control the car in a crisis feels brink start sliding. Also, pay attention to Nokian Hakkapeliitta-5.
At Nokian Hakkapeliitta 4 studs set in 14 rows. The wide dispersal of spikes and improves traction and reduces noise while driving. Located under the spine softening pad cushioned spike on the road, reduces noise from the use of spikes and prolongs the life of the spike. When studded spike set in a very specific position that provides good traction and durability of the spike.
Studding a new type of wear on the road surface is less than the traditional one. The innovative development called Nokian Eco Stud System 4. Patented innovation.
Wide tread improves driving stability.
Main factor of safe winter tires - perfect grip of the ice. During the winter in the northern capricious way the tires needed and more. Drivers appreciate such features as the tire stability and versatility, then they can ride safely and comfortably, not feel the pain of surprises weather: ice, snow, slush or water.
The width of the tread Nokian Hakkapeliitta 4 increased by 10% compared to the previous analog. Wide and flat tread ensures stable behavior of tires on a dry surface and improves traction characteristics on wet and icy road. Wider tread enables spread spikes, thus improving the efficiency of coupling. Changed as the form of the lower layer of the treadmill. Located above the steel-belted harder rubber layer section of the middle part of which is enhanced greatly improves sensitivity and handling on dry surfaces. Increased width and steel belt. This ensures better handling and durability of the tire carcass.
New tire tread design also subject to change. Increased the number of slats. Thanks to some 2,000 sipes provide maximum grip on snow and ice. Curving outward fins have a zigzag shape. They firmly "bite" into the surface of the track. Located beneath the tread sipes enhance agents work with slats slippery roadway.
Tread Nokian Hakkapeliitta 4 is composed of angular pieces. Arrow-drawing, and opens wide on either side grooves allow the self-cleaning tread wheel and take out a layer of snow and water porridge.
"Snap" the rubber mixture makes canola oil.
Angular and hard-bitten character Nokian Hakkapeliitta 4 mitigates environmental rubber compound. Most of the oil used in it is not harmful to the environment, it is grown in Finland environmentally friendly canola oil. Natural oil improves grip of tires in the winter and a wet track, and tensile strength. Winter tire Nokian Hakkapeliitta 4 - more environmentally friendly product, and because of this tire rubber mixture contains only low-aromatic oils and contains absolutely no vysokoaromaticheskih, environmentally harmful oils.
And a few highlights.
In addition to all of the innovations in the structure and form of tongue and in the rubber compound with Nokian Hakkapeliitta 4 has a few small surprises, brighten everyday drivers. Indicators of the degree of wear on the tires indicate the remaining groove depth in millimeters. In the area of the bead is the O-ring that protects against dirt, sand and wet snow between the disc and bead. On the side of the tire is the info site that facilitates storage location of tires on the car when the seasonal change.
Design Nokian Hakkapeliitta 4 has a sporty character. The range consists of low-profile tires and large diameter - 16, 17 and 18 inches. For modern powerful cars need safe winter tires, stable and compliant management. Nokian Hakkapeliitta 4 meet strict safety requirements.
- square stud provides great grip;
- excellent driving stability and low noise;
- Safe bus and slush on the road.
