▼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 a

and an accident.
CAUTION
A wrong-sized wheel may adversely
a ff ect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration

NOTE
When replacing a wheel, make sure
the new one is the same as the
