That’s a must in snow, slowly and carefully.Slowly and carefully
But seriously, rear is the recommended if you only have 2 socks, but you could always put some on the front if you want.
A thought though - if the driver engaged off road assist, that splits the power (and regen braking) 50-50 I understand. In that case, I may lean towards the front wheels for the socks. Help with steering and braking especially as weight shifts forward during breaking.
What do you think?
