Low-Profile Tires

If the vehicle has 245/35ZR19 or
305/30ZR20 size tires, they are classified
as low-profile tires.
Caution
Low-profile tires are more susceptible to
damage from road hazards or curb impact
than standard profile tires. Tire and/or
wheel assembly damage can occur when
coming into contact with road hazards
like potholes, or sharp edged objects,
or when sliding into a curb. The warranty
does not cover this type of damage. Keep
tires set to the correct inflation pressure
and when possible, avoid contact with
curbs, potholes, and other road hazards.

Summer Tires

High Performance Summer Tires
This vehicle may come with 245/35ZR19 and
305/30ZR20 high performance summer tires.
These tires have a special tread and
compound that are optimized for maximum
dry and wet road performance. This special
tread and compound will have decreased
performance in cold climates, and on ice and
snow. It is recommended that winter tires
be installed on the vehicle if frequent
driving at temperatures below
approximately 5 °C (40 °F) or on ice or snow
covered roads is expected. See Winter Tires
0 262.
Caution
High performance summer tires have
rubber compounds that lose flexibility
and may develop surface cracks in the
tread area at temperatures below 7 °C
(20 °F). Always store high performance
summer tires indoors and at
temperatures above 7 °C (20 °F) when
not in use. If the tires have been
subjected to 7 °C (20 °F) or less, let them
warm up in a heated space to at least
5 °C (40 °F) for 24 hours or more before
being installed or driving a vehicle on
which they are installed. Do not apply
heat or blow heated air directly on the
tires. Always inspect tires before use. See
Tire Inspection 0 272.
