The kilopascal (kPa) is the metric term for pressure.
The tire pressure may be printed in both
kilopascal (kPa) and psi. One psi equals 6.9 kPa.

Tires with a higher than recommended pressure can
cause the following conditions:
• A hard ride
• Tire bruising
• Rapid tread wear at the center of the tire
Tires with a lower than recommended pressure can
'
) cause the following conditions:
)
• A tire squeal on turns
e
Hard steering
" Rapid wear and uneven wear on the edge of
the tread
• Tire rim bruises and tire rim rupture
• Tire cord breakage
• High tire temperatures
• Reduced vehicle handling
• High fuel consumption
• Soft riding
Unequal pressure on the same axle can cause the
following conditions:
• Uneven braking
• Steering lead
• Reduced vehicle handling

GM vehicles now use passenger-metric (P-metric)
sized tires. P-metric tires are available in the
following two load ranges:
• Standard load with 210 kPa (30 psi) maximum
pressure
• Extra load with 240 pKa (35 psi) maximum
pressure
Most P-metric tire sizes do not have exact
corresponding alpha-numeric tire sizes. For example,
a P205/75R15 is not exactly equal in size and
load carrying capacity to an FR78-15. Replacement
tires should be of the same TPC specification number
as those originally on the vehicle. If the TPC
specification number is the same then the following
conditions are the same:
• The size
• The load range
• The construction
If you must replace the P-metric tires with other sizes,
consult a tire dealer. A tire company can best .
recommend the closest match of alpha-numeric to
P-metric sizes within their own tire lines.
