The Michelin Pilot Sport 4S 305/30ZR20 103Y XL tire is for a 2021 Tesla Model S Dual Motor or Tesla Model S Plaid rear 20x11.0" wheel.
On a 2021+ Tesla Model S 20" rear, we highly recommend a 103 load tire. We do not recommend a 305/30/20 99 load.
The Pilot Sport 4S is Michelin's Max Performance Summer tire developed in cooperation with some of the most demanding vehicle manufacturers, including Audi, BMW, Mercedes-Benz and Porsche to utilize key technologies engineered during competition in the 24 Hours of Le Mans. It was designed for serious drivers looking to maximize the performance potential of their sports cars, performance sedans and powerful luxury vehicles. The Pilot Sport 4S excels in warm dry and wet conditions, so like all Max Performance Summer tires, is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
