Recently, I received a call from a longtime Tire Rack customer who was looking for a new set of winter / snow tires for his hybrid SUV. He was surprised to see our Preferred Winter / Snow Tire & Wheel Package didn't feature a narrower tire size. Many drivers benefit from a narrow tires ability to cut through deeper snow, but every driver needs to weigh both the advantages and disadvantages of a narrower size. Below you will find what you need to consider when you assess whether or not to go narrow.
Across the snowbelt, there's a wide variance in the intensity and frequency of deep snow blizzards. If you're not residing in the darkest blue areas in the map above, you have to weigh how much grip you’ll lose with a narrower tire on dry roads. All snow tires, especially those in the Studless Ice & Snow category, will sacrifice dry grip and the narrower footprint will exacerbate this loss.
The weight of your car also will play a role in your selection. Does it have all-wheel drive to power through snow? Narrower snow tires are particularly helpful on lightweight cars like the MINI Cooper because you end up with more weight per square inch of contact patch; and more weight equals more grip. Your narrower snow tires will let you cut through deep snow. With a heavier car like the Toyota FJ Cruiser, you can run a moderate size and still be fine.
