It is important to understand your vehicle's original tire sizes and pressures, and the GVWR (Gross Vehicle Weight Rating) and GAWR (Gross Axle Weight Rating). This information can be found on two labels attached to Model Y.
Both labels are visible on the door pillar when the front door is open.
NOTE: If your Model Y is fitted with Tesla accessory wheels or tires, your Model Y may include an additional label indicating that values may differ from what is stated on the label.

WARNING: Overloading Model Y has an adverse effect on braking and handling, which can compromise your safety or cause damage.
CAUTION: Never store large amounts of liquid in Model Y. A significant spill can cause electrical components to malfunction.
