▼ Replacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling could
be affected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:
Tyre fit
Wheel and bearing life
Ground clearance
Snow-chain clearance
Speedometer calibration
Headlight aim
Bumper height
Tyre Pressure Monitoring System
NOTE
When replacing a wheel, make sure

the new one is the same as the
original factory wheel in diameter,
rim width, and offset (inset/outset).
For details, contact an expert repairer

(we recommend an Authorised
Mazda Repairer).
Proper tyre balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tyres can cause
vibration and uneven wear, such as
cupping and flat spots.
