Different kinds of tires serve different purposes on the road. In Alaska, it is important to understand the difference between all-season tires and winter (snow) tires. Choosing the correct tire ensures the safety of yourself and others while driving on Alaskan roads.
Tread Rubber Compound
Tires are made of different types of rubber compound serving different purposes. Rubber compound retains inflation pressure, provides protection, and provides grip and traction. Tread is made of rubber that provides grip and traction on roads. When comparing all-season tires to winter tires, the biggest difference is tread rubber compound.
Tread rubber needs to be flexible to grip the road during winter months. Different rubber compounds will harden at different temperatures, reducing flexibility. Tread rubber compound in all-season tires hardens around 42 degrees. However, in winter tires, the rubber stays flexible below 42 degrees. During warmer temperatures, all-season tires stays hard to resist wear while winter tires stays soft and wears out faster. Thus the reason it is important to change tires seasonally.
Tread Pattern
In addition to tread rubber, the pattern of tread plays a role in providing traction. Winter tires are made with a tread pattern that pushes away snow and ice. All-season tires are made with a tread pattern that grips roads and pushes away water. Different road conditions and seasons call for different tread patterns.
Tire Pressure
As temperatures fluctuate, tire pressure also fluctuates. It is important to check tire pressure regularly, especially during winter months. Tire pressure can be ok in the morning in the garage and then change in the afternoon after leaving your vehicle outside in the elements all day. Maintaining proper tire pressure ensures tires provide good traction when driving and extends the life of tires. It is a good practice to keep a tire gage in your vehicle.
Change All Tires
When updating tires for winter months, change all four tires on your vehicle. Switching only two tires may save money but this decision is actually more inefficient and dangerous.
It is important to understand that different seasons in Alaska calls for different kinds of tires.
