Cadillac XTS Owner Manual (GMNA-Localizing-U.S./Canada-12032610) -
2019 - CRC - 3/26/18
VEHICLE CARE 279
The Tire and Loading Information
label on the vehicle indicates the
original equipment tires and the
correct cold tire inflation
pressures. The recommended
pressure is the minimum air
pressure needed to support the
vehicle's maximum load carr ying
capacity. See Vehicle Load Limits
0 178.
How the vehicle is loaded affects
vehicle handling and ride comfort.
Never load the vehicle with more
weight than it was designed to
carry.
When to Check
Check your tires once a month or
more. Do not forget to check the
spare tire. If the vehicle has a
compact spare tire, it should be at
420 kPa (60 psi). See Compact
Spare Tire 0 304 and Full-Size
Spare Tire 0 304.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven for
at least three hours or no more
than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to get
a pressure measurement. If the
cold tire inflation pressure
matches the recommended
pressure on the Tire and Loading
Information label, no fur ther
adjustment is necessary. If the
inflation pressure is low, add air
until the recommended pressure is
reached. If the inflation pressure
is high, press on the metal stem in
the center of the tire valve to
release air.
Recheck the tire pressure with the
tire gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would not
be covered by the vehicle
warranty.
Professional Vehicle
If the vehicle has 235/55R18 size tires,
the cold inflation pressure depends on
the vehicle mass and should be
determined by the vehicle
coach-builder. A Tire and Loading
Information label provided by the
final stage manufacturer should be
attached to the B-pillar on the driver
side of the vehicle. If the final stage
manufacturer's label is not present,
contact the coach-builder. Do not use
the tire pressures indicated on the
General Motors label. These tire
pressures are for the incomplete
