Q: What tire sizes are used on the 21-inch UP-03 Model X package?
The staggered layout runs 265/40ZR21 up front on the 21×9.5 ET35 wheel and 285/40ZR21 at the rear on the 21×10.5 ET35. The square setup uses 285/40R21 on all four 21×10.5 corners. These sizes are chosen to sit correctly in the Model X fenders, clear the factory brakes, and carry full family-plus-luggage weight.
