Even in winter you could have a slight pressure problem. Monitoring tire pressure is one of the basic safety rules.
It is also a good way to save fuel because more pressure maximizes surface contact with the ground for four tires and avoid prolonged contact with the road.
Finally, a good pressure helps preserve his tires as long as possible and avoids abrasion and excessive wear of the plug rolling.
In winter, the pressure decreases with the outside temperature (hot gas expands and vice versa). Therefore, in winter, it is recommended to add 0.2 bar pressure to the figures recommended by the manufacturer. Think about it.
