South Korean tire manufacturers impose serious competition on large international concerns. Drivers purchase tires from these brands for excellent value for money. In terms of their reliability, these models are in no way inferior to the products of the largest concerns with a worldwide reputation. To increase demand, some companies are also changing the brand. For example, South Korean Hankook registered Laufenn several years ago. The rubber of this brand is precisely aimed at meeting the demand among motorists in Europe and the USA. One of the company's hits was the Laufenn I Fit Ice LW71 model. Feedback from drivers about the tires presented is only the most flattering.

Purpose

Tires designed specifically for sedans. Tires for passenger cars differ from analogues in their reduced mass index. They will not withstand heavy loads. This model is available in 68 sizes with fit diameters from 13 to 18 inches. This solution allows you to fully cover the segment of budget small cars, sedansmid-range and premium cars.

Season

Winter tires. Chemists have developed the most soft compound. As a result, the presented rubber can withstand even severe frosts. This is fully reflected in the reviews of the Laufenn I Fit Ice LW71. At the same time, it is better not to use tires during the thaw. At temperatures above 0 degrees Celsius, the rubber becomes rolled. The wear rate increases several times.

Tread design

The South Korean brand pays great attention to the issues of manufacturability. For example, when designing tires, digital simulation methods are actively used. First, the company's engineers develop a computer model, and then create its physical prototype. With satisfactory test results at the company's test site, tires fall into the series.

During the development of the Laufenn I Fit Ice LW71 tire, they gave it a classic winter tread pattern. Five stiffeners form a symmetrical directional design. The advantage of this approach is the accelerated removal of snow from the contact area. Tires don't skid. Stability and reliability of control is maintained even on loose surfaces.

The central edge is solid. On its edges there are notches beveled at an angle. The presented approach allows these tires for passenger cars to maintain their geometry during high-speed traffic. As a result, the car holds the road better, the need to adjust the trajectory is minimal. One condition -correct balancing after installing new wheels.

Other ribs of the central part consist of sides beveled at an acute angle to the road, made in the shape of a parallelepiped. This type of design provides accelerated removal of snow from the contact area. Bonus - improving the quality of a set of speed. The car accelerates faster, the risk of skidding is reduced to zero.

Shoulder zones are completely open. They consist of small rectangular blocks. The presented geometry allows these elements to maintain stability during braking and cornering. In reviews of the Laufenn I Fit Ice LW71, motorists talk about low braking distances and reliable maneuvering. Skids excluded.

Behavior on Ice

The most serious problems when driving in winter occur when driving on an icy road. The ice is melting. This causes water to form between the tire and the belt. It reduces the quality of contact, leads to a complete loss of controllability. These winter tires are studded. The spike heads cut through the microfilm of water and ensure reliable contact with the surface. At the same time, the manufacturer Laufenn I Fit Ice LW71 has taken a number of specific measures to further improve the stability of movement.

Firstly, the heads of the spikes received a multifaceted shape with a variable section. This prevents loss of control during sharp turns or braking. In any driving vectors, the control remains stable and confident.

Secondly, the variable arrangement of the spikes allowseliminate the rut effect. Maneuvering reliability is excellent.

The spikes themselves are made from a special lightweight aluminum-based alloy. This decision is due to the strict standards of European countries adopted regarding winter studded tires. The fact is that the asph alt canvas suffers from this type of tire. The steel spikes create micro-cracks in the asph alt that only get bigger with time.

A few words about wet asph alt

Frequent thaws in winter lead to thawing of snow. There are puddles. When moving along them, the effect of hydroplaning is formed. The car loses the road, there are uncontrolled demolitions to the side. South Korean engineers managed to deal with this problem thanks to a set of measures.

Firstly, the directional symmetrical pattern is the best solution for fast water drainage. This design is even used in specific rain tires.

Secondly, the model was endowed with a developed drainage system. It consists of five longitudinal deep grooves, combined into a common structure by many transverse tubules. When moving, a centrifugal force arises, which draws the fluid deep into the tread. The water is then redistributed and diverted to the side.

Thirdly, silicic acid is used as part of the compound. Thanks to this connection, the quality of contact with the roadway is improved. In reviews of the Laufenn I Fit Ice LW71, drivers note the reliability of maneuvering on wet roads. Tires practically stick to asph alt.

Durability

The advantage of this model is decent durability. Tires are able to overcome 50 thousand kilometers. It was possible to achieve such parameters thanks to a whole set of measures.

Hankook chemists used carbon compounds in compounding. This technique reduced the rate of abrasive wear. The protector wears out slowly. Its depth remains consistently high for as long as possible.

Rounded tire profile improves the quality of external load distribution. Wear is even. There is no pronounced emphasis on the shoulder part or the central zone. There is only one condition - constant monitoring of tire pressure. In pumped wheels, the central part is erased noticeably faster. Lowered ones wear shoulder ribs.

Comfort Issues

Rubber is soft. The compound itself extinguishes the excess energy that occurs when driving on rough roads. Shaking in the cabin is minimal.

Problems arise due to increased noise. In principle, this disadvantage is typical for all winter tires equipped with studs. The presented model in this case was no exception.

Opinions

The high performance of the Laufenn I Fit Ice LW71 declared by the brand is also confirmed by the tests carried out. The independent German bureau ADAC noted above all the reliability and stability of the tire in various operating conditions. Tires of this type are not afraid even of a sudden change of coverage.
