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.
You can use your Bluetooth-capable
phone
hands-free in Model Y provided your phone
is within operating range. Although
Bluetooth typically supports wireless
communication over distances of up to
approximately 30 feet (nine meters),
performance can vary based on the phone
you are using.
