Summer Tires

High Performance Summer Tires
This vehicle may come with 245/
40R18 (front) and 275/35R18 (rear)
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 0 303.
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
