Forgot to add. On the 1st of january of this year I tried to go up a mountain close to my city. There had been fresh snowfall. We were 4 in the car and I was using 195/65 r15 snow tires (
sava eskimo s3). I also have lots of junk in the trunk and a heavy lpg tank in the spare tire compartment. Even with all that weight in the back, 3 people sitting in the back seat and the winter tires I'd just slide without even touching the throttle pedal. FWD cars would go up though, only to get stuck about 100 meters up.
It was very slippery though. I could barely walk.
