The Michelin X-Ice is another line of winter tire that has been on the market for a long time. It’s still an excellent option and one of the most well-rounded winter tires in terms of braking, acceleration, and handling.
Heat is really hard on winter tires, which are meant to be used when temperatures are ~45°F or below. Winter tires that are run on hot pavement tend to wear out much faster. Winter tires are designed for traction, not longevity, whereas all-season tires are designed for lower rolling resistance and longer tread life.
Winter tires are generally made of a much softer rubber compound than all-seasons, hence the lower wear ratings. Few tiremakers even advertise or post expected distance use to avoid consumer conflict. Michelin is one of the few exceptions; its best wear rating is only 60,000 kilometres.
Expect to spend from $150 to almost $190 per tire, installed, for top-quality brands. While the tread life of winter tires has improved dramatically, it’s not smart to wear out their rubber in hot months.
In addition, most manufacturers suggest replacing your tires when the tread depth reaches 4/32” in the winter. If you allow your tires to wear to the levels above you are driving on what is considered a bald tire (and a huge safety hazard).
