With winter coming with snow and coldness, it is time to change for winter tires. But why? In what way is winter tire different from summer tire or 4 season tire?
1. Formula
Winter tires use special compound to keep the tread rubber soft in temperature below 7 degrees centigrade.
2. Pattern
Winter tires have wider and deeper grooves in spite of numerous sipes to improve water evacuation efficiency.
3. Shoulder
Shoulders of winter tire are in angular shape to enlarge contact area with the road.
4. Studs
Snow tires even use studs to improve traction and braking performance.
In one word, all the effort is aimed to improve traction and prevent skid to ensure stable and safe driving on cold, wet or icy roads.
