Why do I need a winter tires + air conditioning in the summer

Why do I need a winter tires + air conditioning in the summer The weather is getting colder, which is bad for the car, not only on the road, but also in the Parking lot. Also, there are complications with the heating and cooling systems, and you will have to deal with a non-functioning thermostat. Do you need to carry a valve for the steering wheel thermostat in the summer, or is it better to leave it at home? Is it worth carrying a valve in the summer, or in winter? If you have had a valve in the summer, then please tell us about your experiences and what it is like to use it in the fall and winter. I will start with the fact that the valve in the summer is much more powerful than in winter. In the warm season, the valve is responsible for the main work, it is for this reason that the valve steering wheel air conditioner is set at a lower temperature . The valve in the summer, in my experience, it is much more powerful than in winter, not only in terms of heating the interior, but also of the fuel system. Because of this, the sameness of the temperature of the air conditioner turns into a factor that determines the quality of operation of the system. In the fall, the valve is still better left alone, but it is worth carrying a valve with you. Because of how active the valve is in the circulation of air, it can overheat the body. In addition to the valve itself , it is also necessary to set the filter on the valve .

After installing the valve in the vehicle, you need to set it to the desired temperature. As a result, the valve opens to receive air, which warms the interior and makes the operation of the unit more convenient. You can't set the valve in the summer on the "down" position! What does the valve in the summer do? The valve in the summer is responsible for the main work, it is for this reason that the valve in the summer is warmed up. For example, in summer, the valve receives air from the street, passes air from the porch to the passenger compartment, and then sends another set of air to the terrace. In winter, the valve is heated up even more and sends additional cold air to the rear window. In the end, the valve in the summer is like the valve in winter, only more powerful. When the valve is warmed up in the summer, it is the same air that goes into the cabin. Thus, you can set the valve down for the summer and drive safely. If you have a set of tires that is compatible with both seasons and are not affected by the change of air, then it would be helpful to set it so that it is always
