• Tire pressure

• Engine power

What is the main reason for the reduced range of electric vehicles when using winter tires?

• Softer tire compounds

• Heavier weight of the EV

• Increased rolling resistance

• Increased tire noise

What is the purpose of the knurling inside the grooves of the winter tire?

• To increase tire noise
