Chrysler 300 Wheel Bolt Pattern and Offset
Direct Answer
Most Chrysler 300 models use a 5x115 mm wheel bolt pattern with a 71.5 mm center bore. The factory wheel offset commonly sits between about +18 mm and +24 mm, depending on wheel width and model year. The first-generation 300C, which was sold from 2005 through 2010, also uses 5x115 mm. Later second-generation models from 2011 onward continue with the same bolt pattern, so wheels from a first-generation 300C can generally bolt onto a later 300 if the width, offset, brake clearance and tire size are compatible.
What the Bolt Pattern Means
A 5x115 mm pattern means the wheel has five lug holes and the diameter of the circle passing through the center of each lug hole is 115 millimeters. This is different from the 5x114.3 mm pattern used on many other vehicles; a wheel with a 5x114.3 mm pattern should not be forced onto a Chrysler 300 hub, even though the difference sounds small.
Chrysler 300C Wheel Bolt Pattern
The 300C trim does not change the bolt pattern. First-generation 300C cars with the 5.7L Hemi V8 use the same 5x115 mm bolt circle as V6 models. Second-generation 300C models, including later 5.7L and 6.4L variants, also use 5x115 mm. The more important fitment variable for a 300C is brake caliper clearance, especially when fitting smaller-diameter wheels.
Chrysler 300 Wheel Offset
Wheel offset is the distance from the wheel's mounting surface to the centerline of the wheel, measured in millimeters. Positive offset means the mounting surface sits toward the outside of the wheel, which pulls the wheel inward. The Chrysler 300 uses positive offset wheels. Factory 17-inch wheels are often around +18 mm to +20 mm, while wider 18-inch and 20-inch factory wheels can be around +20 mm to +24 mm.
Fitment by Generation
Generation | Years | Bolt Pattern | Center Bore | Typical Factory Offset Range; First generation | 2005-2010 | 5x115 mm | 71.5 mm | +18 mm to +24 mm; Second generation | 2011-2023 | 5x115 mm | 71.5 mm | +18 mm to +24 mm
Center Bore and Hub Fitment
The Chrysler 300 uses a 71.5 mm center bore. Factory wheels are hub-centric, meaning the wheel centers on the hub rather than relying only on the lug nuts. Aftermarket wheels with a larger center bore should be used with hub-centric rings to prevent vibration. A wheel with a smaller center bore will not seat properly on the hub and should not be installed.
Wheel Offset and Backspacing
Offset is related to backspacing, but they are not the same measurement. Backspacing is the distance from the mounting surface to the inner rim edge. A lower positive offset pushes the wheel outward, which can create clearance for wider tires but may also cause rubbing on the fender. A higher positive offset tucks the wheel inward and can interfere with suspension or brake components.
Practical Fitment Notes
Factory 17x7 wheels are commonly paired with offsets around +18 mm to +20 mm. Factory 18x7.5 and 20x8 wheels often use offsets around +20 mm to +24 mm. A 20x9 wheel with an offset near +25 mm to +35 mm can fit many 300 models, but tire size and suspension height affect clearance. On AWD 300 models, front and rear wheel specifications are usually the same, and tire sizes should remain closely matched.
300C Brake Clearance
The 300C, especially versions with larger brake packages, may require at least 18-inch wheels for caliper clearance. Some 17-inch factory wheels may not clear the larger calipers on later 300C or high-performance variants. Test-fitment or checking the factory wheel size for the specific year and brake package is necessary before installing a smaller wheel.
Lug Nuts and Torque
The Chrysler 300 uses metric lug nuts. The factory seat type is typically a 60-degree conical or acorn seat, but aftermarket wheels may require a different seat style such as a ball seat or flat seat. Factory lug torque for many model years is approximately 110 to 130 lb-ft, but the exact value depends on the year and owner's manual specification. Lug torque should be checked after the first 50 to 100 miles following wheel installation.
What to Verify Before Buying Wheels
Confirm the year and drivetrain, because AWD and RWD models can have different factory wheel widths and offsets. Check the factory wheel width and offset printed on the back of an original wheel or in the owner's manual. Verify the center bore is 71.5 mm or larger and use hub rings if it is larger. Confirm the lug nut seat matches the wheel, not just the vehicle. Measure brake caliper clearance, especially on 300C or high-performance trims. Keep the overall tire diameter close to factory when changing wheel size.
Common Misconceptions
A 5x114.3 mm wheel is sometimes described as fitting a 5x115 mm hub, but this is not a correct fit. The difference is less than a millimeter, but it can cause uneven lug seating, vibration and premature wear. Offset is sometimes confused with spacer thickness; adding a spacer effectively reduces the wheel's positive offset and pushes the wheel outward.
Summary
The Chrysler 300 uses a 5x115 mm bolt pattern across its main generations and across the 300C trim. The hub bore is 71.5 mm, and factory offset is generally positive, ranging from about +18 mm to +24 mm depending on wheel width and year. When changing wheels, the critical checks are bolt pattern, center bore, offset, brake clearance, lug seat type and overall tire diameter.
