Maintenance and care
Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause loss of handling control.
■Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset
*.
Replacement wheels are available at your Scion dealer.
*: Conventionally referred to as “offset”.
Scion does not recommend using:
●Wheels of different sizes or types
●Used wheels
●Bent wheels that have been straightened
■Aluminum wheel precautions
●Use only Scion wheel nuts and wrenches designed for use
with your aluminum wheels.
●When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
●Be careful not to damage the aluminum wheels when using
tire chains.
●Use only Scion genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.
