Tire pressure depends on the exact tires fitted, so use the Tire Information label in your driver’s door jamb rather than a number from the internet. There’s no spare: see what to carry instead.
Lug nuts
Model Y lug nuts take a 21 mm socket. Tighten them with a torque wrench to the value in your owner’s manual, and protect the battery when the car is lifted with proper jack pads.
Wiper blades
Tesla’s Model Y spec is a 26-inch blade on the driver’s side and a 20-inch blade on the passenger’s side, with a connector identical to the original. The connector changed on Model Ys built from about February 2025 (the Juniper), so the right blade depends on your car’s year.
