  7. Can your tires survive...

[YesAuto Tire Interpretation] Can four-season tires survive the winter? Every year we talk about winter tires, but many people will mention the four-season tires: “Can't it also be used in winter”? A reply from a netizen made me speechless.

Coincidentally! Not long ago, we caught up with Kumho Tire’s internal testing of all-season tires in Northeast China. Their purpose is to test the performance of all-season tires on icy and snowy roads. With their opportunity, I helped you find out ” standard answer”. Can Season Tire accompany you through the winter safely? Is there no need to consider winter tires with four-season tires? Let us learn from practice!

Tips: Winter tires? Snow tires?

Before the official start, we first correct a misunderstanding as usual. Many people are used to calling winter tires snow tires. In fact, there are still differences between these two types of tires. According to international standards, tires suitable for environments below 7°C are called winter tires, while the studded snow tires with nails seen on the roads of some rally races, including some “Arctic Circle countries”, are a special type of snow tire. Tires cannot be used on public roads in China. In recent years, this type of tire has become more and more rare and has a tendency to be eliminated. The tires discussed in this article are precisely winter tires.

“Four season tires & winter tires, who fooled you?”

Tires are car shoes. They are the same as human shoes. They are changed according to the season, temperature, road conditions, etc. Just like you don’t wear slippers to climb mountains to play golf, no tire can adapt to all seasons. And the road surface, this not only involves adhesion, but also involves many factors such as temperature, but in reality, “tires are not as good as shoes”, and it is often the world with one child. People are afraid that they will fall when they wear shoes incorrectly. Are tires not afraid of it?

Speaking of this, I have to mention the four-season tires. Everyone knows summer tires, but the four-season tires are more like a “neutralizing” product, giving everyone the feeling of an all-round tire, which can adapt to summer and winter. From the name, it seems that it is indeed the way to travel the world with one child.

This is not the case. Judging from the testing experience of tire companies, below minus 7°C, the rubber of all-season tires will react to hardening and embrittlement. The hardened and brittle tread will also almost lose the deformation ability of the pattern and become a ” Hard-faced”. As a result, its adhesion to snow and icy roads is greatly reduced. If you encounter a turn at this time, it is really “powerless every second.”

Real knowledge from practice: controllable & uncontrollable

In all the test items below, it is the most commonly used driving state. The Vehicle Stability System (VSC) remains on by default, and the D gear is used throughout.

Through this small video, I believe you have already seen the huge difference between four-season tires and winter tires on hard snow roads. Many people think that winter tires and four-season tires are a good-to-bad relationship, but from a practical point of view, they are more like the relationship between usable and unavailable, controllable and uncontrollable. You can clearly see that the controllability of the all-season tires on hard snow roads is very low, and the traction is greatly lost. Especially when turning, its tracking performance will become worse, or even suddenly lose tracking, your control of the vehicle will be reduced to a minimum at this moment, or even zero.

In the winter tires, there has been a qualitative leap. Whether it is accelerating braking or sudden steering, all operations have become very controllable. Whether it is the propulsion caused by the traction when the vehicle is accelerating, or the tracking caused by the adhesion of the wheels and the ground when turning, you will clearly feel this sense of control. This is not just a psychological effect. It is a question of safety and insecurity.

Comparison of driving on ice: the difference between life and death

The difficulty continues to increase! We arrived at another ice test site in the proving ground, where I will compare winter tires and all-season tires in response to icy roads. For most of the northern and northeastern provinces in China, icy roads are often encountered in many cities and towns in winter. It is more difficult and dangerous than snowy roads! Sometimes it's just a brake or a corner, and disasters follow, and its controllability is almost zero! Survival depends entirely on luck.

The editor said: Don't get lucky, just change if you need to change it!

Soon after the test, I chatted with the local driver master, and from everyone’s feedback, we can draw a point that many people think that winter tires are useless or useless, but you didn’t expect it. , Once there is a danger or encounter some special roads, it may be the difference between life and death at that moment. Just like some people in the cross-country circle say that it is useless to install a winch, you may not use it in your life, but one use can save your life. The same is true for winter tires.

Well, the content of the comparison between the four-season tires and winter tires in this issue is here. I believe that through this subjective comparison, everyone should have a new understanding of the actual gap between winter tires and four-season tires. Is it worth buying? I believe that everyone has their own answers in their hearts. See you next time!
