The Winter Tire Opportunity – Now Is The Time

Winters tires aren’t just a luxury, it’s your job to tell your customers the positive impact that the tires can give them.

It was a frigid February morning in Chicago last year. The kind of cold that creeps into the depths of your lungs, making it difficult and even a little painful to breathe. The kind of cold that literally takes your breath away. The snow was falling as I stepped into my car and took off across The Chicago Skyway with the city lights in my rear view. It was around Gary, Indiana, that the lake effect snow engulfed Interstate 90 and made it impossible to see the road more than about 15 feet ahead as I made an unwise attempt to pass a massive snowplow in the right lane. And, it was this moment that I understood the difference between an all-season tire and a true winter tire. My life as a “tire guy” would never be the same again.
