Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 2111
WHEELS
DESCRIPTION
WHEEL
All vehicles use either steel or cast aluminum drop
center wheels. The original equipment wheels are
designed for proper operation at all loads up to the
specified maximum vehicle capacity.
Every wheel has raised sections between the rim
flanges (1) and drop well (3) called safety humps (2).
In case of air loss, these raised sections help hold the
tire in position on the wheel until the vehicle can be
brought to a safe stop. When being installed on the
wheel, initial inflation of the tire forces the tire bead
over these raised sections into place.
The wheels used on All-Wheel-Drive (AWD) vehicles
have a shallower dish (larger offset) than Rear-Wheel-
Drive (RWD) wheels to accommodate the AWD sus-
pension geometry and half shaft package, while
maintaining the same track as RWD vehicles.
The wheel studs and nuts are designed for specific wheel applications and must be replaced with equivalent parts.
Do not use replacement parts of lesser quality or of a substitute design. All aluminum and steel wheels have wheel
stud nuts with an enlarged nose. This enlarged nose is necessary to ensure proper retention of the wheels.

DIAGNOSIS AND TESTING
WHEEL INSPECTION
Inspect wheels for:
•
Excessive runout
•
Dents, cracks or irregular bends
•
Damaged wheel stud (lug) holes
•
Air Leaks
NOTE: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged, an original equipment replacement wheel should be used. When obtaining replacement
wheels, they should be equivalent in load carrying capacity. The diameter, width, offset, pilot hole and bolt circle of
the wheel should be the same as the original wheel.

WARNING: Failure to use equivalent replacement wheels may adversely affect the safety and handling of
the vehicle.
WARNING: Replacement with used wheels is not recommended. The service history of the wheel may have
included severe treatment or very high mileage. The rim could fail without warning.
CLEANING
WHEEL AND WHEEL TRIM CARE
All wheels and wheel trim, especially aluminum and chrome plated, should be cleaned regularly using mild soap and
water to maintain their luster and to prevent corrosion. Wash them with the same soap solution recommended for
the body of the vehicle.
When cleaning extremely dirty wheels, care must be taken in the selection of tire and wheel cleaning chemicals and
equipment to prevent damage to the wheels. Mopar
