Tires

For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-7)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.
qTire Inflation Pressure
WARNING
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of
tires is dangerous. Adverse handling
or unexpected tire failure could result
in a serious accident.
Refer to specification charts on page
10-7.

Some models.
The Tire Pressure Monitoring System
does not alleviate the need to check the
tire condition every day, including
whether the tires all look inflated properly.
Inspect all tire pressure monthly when the
tires are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tire wear.
When checking the tire pressures, use of a
digital tire pressure gauge is
recommended.
Refer to the specification charts (page
10-7).
NOTE
Always check tire pressure when tires are
l
cold.
Warm tires normally exceed recommended
l
pressures. Don't release air from warm tires
to adjust the pressure.
Underinflation can cause reduced fuel
l
economy, uneven and accelerated tire wear,
and poor sealing of the tire bead, which
will deform the wheel and cause separation
of tire from rim.
Overinflation can produce a harsh ride,
l
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
