Cadillac 2006 XLR - Manual (Page 370)

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
A Tire and Loading Information label is attached to the
center pillar, below the driver’s door latch. This label
shows your vehicle’s original equipment tires and
the correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation pressure,
shown on the label, is the minimum amount of air
pressure needed to support your vehicle’s maximum
load carrying capacity.
For additional information regarding how much weight
your vehicle can carry, and an example of the tire
and loading information label, see Loading Your Vehicle
on page 5-33. How you load your vehicle affects
vehicle handling and ride comfort, never load your
vehicle with more weight than it was designed to carry.
When to Check
Check your tires once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires may look
properly inflated even when they are underinflated.
Check the tire’s inflation pressure when the tires
are cold. Cold means your vehicle has been sitting
for at least three hours or driven no more than
1 mile (1.6 km).
