Piston Slap: Faith in the Three Peak Mountain Snowflake?

Greg writes:

Good day Sajeev,

I recently signed a three-year lease on a Grand Cherokee Upland. The Upland is an appearance group that includes tow hooks, blacked-out trim and great big (20”) wheels wrapped in some fairly aggressive all-terrain tires (Goodyear Wrangler All Terrain Adventure). Boy, does FCA love “appearance groups.”

I live in the great white snow belt of Western New York where we get around 100 inches of snow per year. On my last two vehicles (Ram 1500 and Toyota 4Runner), I used winter tires for about 4 months of the year and was very happy with them.

I have the opportunity to purchase winter tires on steel wheels for this Jeep at a steep discount from a coworker. My question is, do I need them or should I rely on the A/T’s that are on the Jeep already? The stock tires are well-reviewed for winter use but I’ve heard horror story about low profile tires and big rims in the snow.

What’s your take?
