Tire Care and Maintenance
The TPMS malfunction indicator is
combined with the tire pressure
indicator light. When the system
detects a malfunction, the indicator
flashes for approximately one minute
after Model S powers on, and then
remains continuously lit. This
sequence continues upon
subsequent vehicle start-ups as long
as the malfunction exists. When the
TPMS malfunction indicator is on,
the system might not be able to
detect or signal under- and over-
inflated tires as intended.
TPMS malfunctions can occur for a variety of
reasons, including installing replacement or
alternate tires or wheels that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction indicator light after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement tires or
wheels allow the TPMS to continue to function
properly.
Note: If a tire has been replaced or repaired
using a different tire sealant than the one
available from Tesla, and a low tire pressure is
detected, it is possible that the tire sensor has
been damaged. Contact Tesla to have the fault
repaired as soon as possible.

Seasonal Tire Types
Summer Tires
Your vehicle may be originally equipped with
high performance summer tires or all season
tires. Tesla recommends using winter tires if
driving in cold temperatures or on roads
where snow or ice may be present. Contact
Tesla for winter tire recommendations.
Warning: In cold temperatures or on snow
or ice, summer tires do not provide
adequate traction. Selecting and installing
the appropriate tires for winter conditions
is important to ensure the safety and
optimum performance of your Model S.
All-Season Tires
Your Model S may be originally equipped with
all-season tires. These tires are designed to
provide adequate traction in most conditions
year-round, but may not provide the same
level of traction as winter tires in snowy or icy
conditions. All-season tires can be identified
by "ALL SEASON" and/or "M+S" (mud and
snow) on the tire sidewall.
Winter Tires
Use winter tires to increase traction in snowy
or icy conditions. When installing winter tires,
always install a complete set of four tires at
the same time. Winter tires must be the same
size, brand, construction and tread pattern on
all four wheels. Contact Tesla for winter tire
recommendations.
Winter tires can be identified by a
mountain/snowflake symbol on the
tire's sidewall.
When driving with winter tires, you may
experience more road noise, shorter tread life,
and less traction on dry roads.
Driving in Low Temperatures
Tire performance is reduced in low ambient
temperatures, resulting in reduced grip and an
increased susceptibility to damage from
impacts. Performance tires can temporarily
harden when cold, causing you to hear
rotational noise for the first few miles
(kilometers) until the tires warm up.
