21x9 wheels pretty much dictates that you're going to use 245/35R21 tires (Tesla's standard size tires for 21" wheels). The wheel itself will fit 255 and 265 tires, but there are no 255/35R21 tires available, and 265 tires would rub the inside of the front wheel wells.
In 245/35R21 tires, there are fewer selections available than other sizes, and all of them are summer tires (no all seasons), or there are a couple winter tires. None of them are rated for low rolling resistance.
The ones with the best noise profile will be:
1. Michelin Pilot Super Sport
2. Michelin Pilot Sport PS2
3. Continental ExtremeContact DW
4. Continental Contisport Contact 5P (these have the ContiSilent technology)
You might consider the Vossens in a 20x9 instead. There's a larger tire selection in 245/40R20 and 255/40R20, and there is a low-rolling resistance tire available, the Pirelli Cinturato P7 All-Season Plus. The Pirelli Cinturato has a bit lower traction for launches, but this should not be an issue with the Model S 70.
