Just purchased a beautiful new RLine Tiguan with 20 inch tires. Living in snow country of the Tetons so, bought new Continental Viking snow tires. The Tiquan is darting all over the snow packed road at hiway speed. Crazy situation and having trouble figuring this issue out. Tires? Size? Anyone else experiencing this in real snow conditions? Have owned a few Outback’s prior to this vehicle with no issues like this. Alignment was just checked as well. Love the car but, will need to solve this soon. Thanks for any suggestions.
