I currently have an order for a LR Model Y and I’m thinking of modifying it to a Performance, but I’m having trouble finding 21” winter tires. I can find a few that fit the rear, but can’t find fronts anywhere. The 19” & 20” packages on the Tesla site both say they’re NOT compatible with the Model Y Performance. Is this because 19” or 20” don’t fit due to the brakes? Can any Performance owners let me know what your winter tire setup is and where you ordered from? Thanks.
