Tire Sidewall Labeling - Cadillac XT5 2017 Owner's Manual

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 0 296.
