Cadillac 2004 SRX - Manual (Page 378)

Treadwear Indicators: Narrow bands, sometimes
called “wear bars,” that show across the tread of a tire
when only 2/32 inch of tread remains. See
When It
Is Time for New Tires on page 5-72.
UTQGS: Uniform Tire Quality Grading Standards,
a tire information system that provides consumers with
ratings for a tire’s traction, temperature and treadwear.
Ratings are determined by tire manufacturers using
government testing procedures. The ratings are molded
into the sidewall of the tire. See
Uniform Tire Quality
Grading on page 5-74.
Vehicle Capacity Weight: The number of designated
seating positions multiplied by 150 lbs. (68 kg) plus
the rated cargo load. See
Loading Your Vehicle
on page 4-48.
Vehicle Maximum Load on the Tire: Load on an
individual tire due to curb weight, accessory weight,
occupant weight and cargo weight.
Vehicle Placard: A label permanently attached to a
vehicle showing the original equipment tire size
and recommended inflation pressure. See
Loading Your
Vehicle on page 4-48.
Inflation - Tire Pressure
The Certification/Tire label or Tire and Loading
Information label shows the correct inflation pressures
for your tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than 1 mile (1.6 km). See
Loading Your
Vehicle on page 4-48.
Notice: Don’t let anyone tell you that underinflation
or overinflation is all right. It’s not. If your tires
don’t have enough air (underinflation), you can get
the following:
• Too much flexing
• Too much heat
• Tire overloading
• Bad wear
• Bad handling
• Bad fuel economy
If your tires have too much air (overinflation),
you can get the following:
• Unusual wear
• Bad handling
• Rough ride
• Needless damage from road hazards
