so something quite weird happened last night. i noticed that when i went about 50mph and above, the entire car started shaking (like the wheels would about to pop off). i pulled over, check the tires, and found no obvious problems. the only things that i could think of was the snow buildup in the wheel wells cuz we just had a huge snowstorm here in denver. i drove to work this morning and there was a lot less shaking (if not gone completely). any inputs/thoughts on what this could have been?
