{CAUTION:
Run-flat tires are constructed differently than
other tires and could explode during improper
service. You or others could be injured or
killed if you attempt to repair, replace,
dismount, or mount a run-flat tire. Let only an
authorized run-flat service center repair,
replace, dismount, and mount run-flat tires.
The valve stems on your vehicle’s run-flat tires have
sensors that are part of the Tire Pressure Monitor
System (TPMS). These sensors contain batteries which
are designed to last for 10 years under normal driving
conditions. See your GM dealer, if the TPMS sensors or
a wheel ever need replacement.
Notice: Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
vehicle’s run-flat tires. This damage would not
be covered by warranty. Do not use liquid sealants
in your vehicle’s run-flat tires.
Inflation - Tire Pressure
Tires need the correct amount of air pressure to operate
effectively.
Notice: Do not let anyone tell you that
under-inflation or over-inflation is all right. It is not.
If your tires do not have enough air (under-inflation),
you can get the following:
• Too much flexing
• Too much heat
• Tire overloading
• Premature or irregular wear
• Poor handling
• Reduced fuel economy
If your tires have too much air (over-inflation), you
can get the following:
• Unusual wear
• Poor handling
• Rough ride
• Needless damage from road hazards
