Are you somebody who lives in an area that frequents snow and ice? If so, you will need winter tires. Below is a buying guide to ensure that you equip your vehicle with the proper type of tire. What does this mean? Winter tires are marked with a pictograph of a peaked mountain with a snowflake. These tires meet specific snow traction and severe snow condition requirements during wintertime.
Tires marked "M & S" or "Mud & Snow" tires, commonly known as "All Season" tires provide safe all-weather performance, but tend to fall short under severe winter conditions. Furthermore, M & S tire requirements are guidelines and involve no actual testing to receive the M & S designation, while winter tires must meet strict performance-based requirements.
Winter tires have special tread compounds that use one or more of the following features to deliver improved traction:
The rubber in an all-season tire starts to lose elasticity and harden at a temperature of 7 degrees Celsius; this greatly reduces the tire's grip on the road. At -15 degrees Celsius, this type of tire will have completely lost all elasticity, whereas a winter tire will only harden around -40 degrees Celsius; therefore, retaining its elasticity for much longer.
Winter tires have tread designs dedicated to improve traction on snow and ice. Today's most advanced winter designs deliver this while maintaining a comfortable, quiet highway ride as well as excellent dry traction.
