Tyres
▼ Tyres
For reasons of proper performance,
safety, and better fuel economy, always
maintain recommended tyre inflation
pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using Different Tyre Types:
Driving your vehicle with different
types of tyres is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tyre, use only the
same type tyres (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tyres:
Using any other tyre size than what is
specified for the vehicle (page 9-10)
is dangerous. It could seriously affect
ride, handling, ground clearance, tyre
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tyres that
are the correct size specified for the
vehicle.
▼ Tyre Inflation Pressure
WARNING
Always inflate the tyres to the correct
pressure:
Overinflation or underinflation of tyres
is dangerous. Adverse handling or
unexpected tyre failure could result in
a serious accident.
Refer to Tyres on page 9-10.
Owner Maintenance
Use only a Mazda-genuine tyre valve
cap:
Use of a non-genuine part is
dangerous as the correct tyre air
pressure cannot be maintained if the
tyre valve becomes damaged. If the
vehicle is driven under this condition,
the tyre air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tyre valve cap that is not a
Mazda-genuine part.
Inspect all tyre pressures monthly when
the tyres are cold. Maintain
recommended pressures for the best
ride, handling, and minimum tyre
wear.
Refer to the specification charts (page
9-10).
NOTE
Always check tyre pressure when

tyres are cold.
Warm tyres normally exceed

recommended pressures. Do not
release air from warm tyres to adjust
the pressure.
Underinflation can cause reduced

fuel economy, uneven and
accelerated tyre wear, and poor
sealing of the tyre bead, which will
deform the wheel and cause
separation of tyre from rim.
Overinflation can produce a harsh

ride, uneven and accelerated tyre
wear, and a greater possibility of
damage from road hazards.
Keep your tyre pressure at the correct
levels. If one frequently needs
inflating, have it inspected.
