What are the disadvantages of using winter tires in summer?

[VonCollin]

The disadvantages of using winter tires in summer include increased tire noise. Winter tires have many asymmetrical and directional tread patterns, along with a high number of grooves. When driving at high speeds, the rapid impact of air against the tread patterns and grooves leads to a significant increase in tire noise, negatively affecting the driving experience. Additionally, using winter tires in summer results in higher fuel consumption and reduced power. To enhance traction on snow, winter tires are typically softer than regular tires (even in low temperatures) and often feature asymmetrical cross-Z-shaped sipes. Driving with such tires on normal summer roads inevitably increases vehicle fuel consumption and reduces power.
