USING SUMMER TIRES
The original equipment tires on your vehicle
are designed to optimize its performance
in dry or wet summer road conditions. The
rubber compounds used in these tires lose
flexibility and may develop surface cracks
in the tread area at temperatures below
19°F (-7°C).
We do not recommend using the original
equipment tires when temperatures drop
below 45°F (7°C) or in snow and ice
conditions.
Storing Summer Tires
Note: Always store your tires indoors at
temperatures above 19°F (-7°C).
If the tires have been subjected to 19°F
(-7°C) or less, warm the tires for at least
24 hours in a heated space to at least 41°F
(5°C):
• Before installing them on a vehicle.
• Before moving a vehicle.
• Before checking tire inflation.
Note: Do not place tires near heaters or
heating devices used to warm the room
where the tires are stored.
Note: Do not apply heat or blow heated air
directly onto the tires.
Note: Always inspect the tires after storage
periods and before use.
USING WINTER TIRES
The original equipment tires on your vehicle
are designed to optimize its performance
in dry or wet summer road conditions.
They are not optimized for off-road or
winter performance and you must not use
them with snow chains. The use of any
type of snow chain with the original
equipment wheels and tires of your vehicle
may cause damage not covered by the
vehicle Warranty. We do not recommend
using the original equipment tires when
temperatures drop below 45°F (7°C) or in
snow and ice conditions.
We recommend that you use winter or
all-season tires when temperatures drop
below 45°F (7°C) or in snow and ice
conditions.
When using winter tires:
•
Do not operate your vehicle above
posted speed limits or perform high
speed maneuvers.
• If you fit winter tires with a speed rating
less than the original equipment tires,
do not exceed the maximum speed
rating for the tire.
