CONDITION
Some models are equipped with front and rear wheels of different offsets or width . Wheel offset,
defined as the distance between the wheel's centerline and the wheel-to-rotor mounting surface ,
affects the clearance between the back of the whee l and surrounding brake components (Figure 1).
Installation of a wheel with an offset or width different than the correct specification , such as installing
the rear wheel on the front , can cause damage to brake components due to interference between the
wheel and adjacent parts. The wheel could contact the brake caliper thereby introducing stress into
the caliper, brake rotor, and potentially other components. In some cases , this stress could contribute
to cracking or separation of the brake rotor.

Note th at wheels of different offsets or width can appear virtually identical even when compared side
by side and therefore the wheels can be inadvertently swapped . Offset and width can be identified by
inspecting the back of the wheel (Figure 2).
Wheel offset information is also available on TIS in the Suspension (Tire/Wheel) section in New Car
Features. Tire size information is located on the vehicle's tire placard .
