What is the speed and load ratings of the OEM Tesla Model S 2019 winter tires? I have 19" slipstream wheels and want to buy right tires. My OEM summer tires with 21" twin-turbine wheels have ratings 96Y front and 101Y rear, but I can't find the same load ratings winter tires. Please, advice what do you use for winter. The vehicle - Model S Performance 2019.
