I agree that my MY seems to just start to wiggle, and then quickly correct itself. It's that momentary wiggle that we almost never get with the Forester with the studded Hakkas. We didn't manage to find the right sized studded Hakka tires for the MY this year (thanks for nothing COVID), but I'll definitely look for them when we need a new set. Now that I've discovered studded tires, I don't think I'll ever go back.As I have posted on this thread before, my Model 3 has been rock solid in slippery and snowy winter conditions. I have experienced only occasional wiggles in the back end, which the traction control has corrected immediately. Maybe the narrower tires make a difference for the Model 3 as compared to the Model Y, although I would not think it would be that much of a difference. And certainly I have a good set of winter tires on. Anyway, I have been very pleased - the Model 3 has been even better on snow and ice than the Subaru that we owned.
