Use snow tires on all four wheels
Don't go faster than 120 km/h (75 mph)
while driving with snow tires. Inflate
snow tires 30 kPa (0.3 kgf/cm
2, 4.3 psi)
more than recommended on the tire
pressure label (driver's door frame), but
never more than the maximum cold-tire
pressure shown on the tires.

summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNING
Mixing Tire Types:
Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result in
an accident. Use only the same size
and type tires (snow, radial, or non-
radial) on all four wheels.
CAUTION
Check local regulations before using
studded tires.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tires with steel wire reinforcement in
the sidewalls (page 5-29).

Check local regulations before using tire
chains.
CAUTION
lChains may scratch or chip
aluminum wheels. Install tire chains
on steel wheels only.

lDon't go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is
lower.
lDrive carefully and avoid bumps,
holes, and sharp turns.
lAvoid locked-wheel braking.
lDon't use chains on roads that are
free of snow or ice. The tires and
chains could be damaged.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tire chains.
Install the chains on the rear tires.
Don't use chains on the front tires.
