Sounds like I'm the exception, but we went back home to Cleveland (currently live in the Charlotte area) at Thanksgiving and while we were there we leased a 2021 Sierra Elevation Double Cab 4x4 with these tires on it. My girlfriend stayed until the day after Christmas to help take care of a family member so I left her the truck and rented a car to drive home. They had several large snow storms before she headed back home to Charlotte, including 15" of snow over the course of the two days before she came home. She said the truck did fantastic in the snow and because it was Christmas Eve and Christmas Day, the roads were hardly touched by the plows and salt trucks. When she drove home the day after Christmas, she drove through snowy conditions for the first couple hours of her drive and said the truck did great in that too. She mostly left the truck in 4x4 auto mode during her time in Ohio, but a couple times put it into 4-Hi. Never had any issues, even when driving on roads that had 6-8" of fresh snow with no tracks from other vehicles to drive in. Unfortunately I didn't get to experience it in the snow first-hand.
I'm wondering if tire pressure could be a factor at all? Ours reads 37 psi on the DIC when warm.
