The following information relates to the tire grading system developed by the
National Highway Traffic Safety
Administration (NHTSA), which grades tires by tread wear, traction and
temperature performance. Tires that have
deep tread, and winter tires, are exempt from these marking requirements.
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.
