Is it necessary to replace all four tires with winter tires?

[LaLevi]

It is best to replace all four tires with winter tires. Material of winter tires: The main tread of winter tires uses some special formulations to generate greater friction, significantly improving the vehicle's handling and safety on slippery ice surfaces. Under low-temperature conditions, winter tires will still maintain a softer texture, while regular tires will harden as the temperature drops. Key technologies of winter tires: The formulation of the tire surface material and the tread pattern technology of winter tires are different from those of regular tires. Winter tires increase friction with snow and ice surfaces through special formulations. Winter tires have deep tread grooves, but they only exhibit optimal adhesion at low temperatures. The situation on snow is different from that on dry roads because, on snowy surfaces, the tire treads interlock with the snow, and traction mainly relies on the tire treads inserting into the snow and ice surfaces to gain power.
