wow I wasn't expecting so many responses.
Thanks a lot for all the help.
someone made a good point about endangering the people around me, which i'm more worried about than the condition of my car.
I'll likely invest in winter tires or just drive the Land Rover to switch it up.
I just don't want to buy tires, have them put on, then have another winter like last with one day of snow.
