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.
When you first adjust the driver's seat, steering wheel
position, or exterior side mirrors, the touchscreen
prompts you to create a driver profile to save these
adjustments. Your profile also saves various preferences
you make while customizing Model Y. See Using Tesla Profiles to learn more abo
