2018 Dodge Charger Wheel Interchange

2018 Dodge Charger Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2018 Dodge Charger

The 2018 Dodge Charger was sold with multiple wheel and tire packages. The values below are confirmed items from OEM configurations, but they may vary by trim, brake package, and option group. Do not assume these items came together on the same vehicle. Always verify your exact build using the on-page calculator, your owner’s manual, the door-jamb tire label, and OEM parts catalogs.

If your vehicle differs, that is normal. The Charger lineup includes multiple brake sizes and wheel packages. Verify by VIN or the tire label on your driver’s door, then use the calculator below to compare any donor wheels you are considering.

How To Use The Wheel Interchange Calculator

• Open the calculator and set Installed on (your vehicle) to 2018 Dodge Charger.
• If you know your current wheel size, enter it. If you are using the example OEM 18 x 7.5 ET 24, input those values. If your tire size is known, enter it too.
• In Wheels from (donor vehicle), select the donor car or type in the Custom wheel size you want to test. You can also enter a Custom tire size for that wheel.
• Changing rim diameter automatically updates the tire diameter readout in the comparison so you can see overall height differences.
• Review inner clearance to the strut or knuckle and outer poke to the fender. The calculator will show how much the inner and outer positions change compared to your current setup.
• Keep overall tire diameter close to your OEM value to maintain speedometer accuracy and avoid ABS or transmission shift issues. A common target is within about 3 percent of stock.
• Confirm brake caliper and spoke clearance. Visualize with the calculator, then physically test-fit whenever possible.
• If any value is unknown for your trim, check the owner’s manual, door-jamb label, Mopar parts catalog, or measure your wheel directly and enter those numbers.

Fitment Checklist Before You Buy

• Bolt pattern: The Charger uses 5x115. Do not substitute 5x114.3 unless a qualified professional confirms a safe solution. Out-of-spec PCD can cause vibration and stud stress.
• Center bore: Vehicle hub is 71.5 mm. Aftermarket wheels with a larger bore must use correct hub-centric rings. A smaller bore will not fit.
• Offset and backspacing: Use the calculator to ensure you do not lose inner clearance to the strut or gain too much outer poke toward the fender. Compare against your current wheel.
• Brake clearance: Some trims have larger brakes. Verify spoke and barrel clearance, especially with smaller offsets or tighter spoke designs.
• Tire load and speed ratings: Match or exceed OEM ratings shown on the door-jamb label.
• TPMS: Plan to transfer sensors or buy compatible new sensors. Verify frequency and relearn steps for your Charger.
• Lug seat style and hardware: Match the nut or bolt seat to the wheel design. Do not mix conical, ball, or mag seats.
• Thread engagement: With M14 x 1.5 studs, ensure sufficient thread engagement. If using spacers, confirm stud length and spacer type.
• Weight and strength: Choose quality, properly rated wheels. Heavier wheels can affect braking and ride.
• Alignment: After significant wheel or tire changes, get an alignment to protect tires and handling.

Plus Sizing And Common Upgrades

Plus sizing trades sidewall height for wheel diameter. Always verify brake, fender, and suspension clearance, and keep overall diameter close to stock for proper drivability.

• Using 245/45R20 as an example OEM tire size on select trims, the overall diameter is about 28.7 in. Aim for new sizes that stay close to that height.
• Wider tires can improve grip but may require different offset to avoid rubbing on the strut or fender. Use the calculator to model inner clearance and outer poke before buying.
• Staggered setups can fit visually but complicate rotation and may affect traction control tuning. Confirm with the calculator and OEM guidance.
• If you have the example 18 x 7.5 ET 24 wheel, model your prospective plus-one or plus-two packages in the calculator and compare position changes to ensure safe clearances.

Installation Tips

• Park on a level surface, chock wheels, and use jack stands under proper lift points. Never rely on a floor jack alone.
• Clean the hub face and the wheel mounting pad to remove rust and debris. A clean, flat interface reduces vibration.
• If the wheel’s center bore is larger than 71.5 mm, install correct hub-centric rings before mounting.
• Hand start all M14 x 1.5 lug nuts to prevent cross-threading. Tighten in a star pattern.
• Use the torque specification from your owner’s manual or Mopar service information. Re-torque after 50 to 100 miles.
• Spacers: Only use high-quality, hub-centric spacers. Ensure proper stud length and thread engagement, and re-check torque after initial miles.

FAQs

• What is the bolt pattern on the 2018 Dodge Charger?

  5x115. Use wheels drilled for 5x115 for proper fit and safety.

• Can I run 5x114.3 wheels on a Charger?

  Not recommended. The 0.7 mm PCD mismatch per stud can cause vibration, accelerated wear, and stud stress. Use correct 5x115 wheels or consult a qualified professional for safe alternatives.

• What is the center bore, and do I need hub-centric rings?

  The Charger hub is 71.5 mm. If your wheel’s bore is larger, use hub-centric rings sized to 71.5 mm on the vehicle side and the wheel’s bore on the wheel side. If the wheel bore is smaller than 71.5 mm, the wheel will not fit.

• What lug nuts does it use?

  Thread size is M14 x 1.5. Match the seat style to your wheel design and follow the wheel manufacturer’s guidance. If reusing OEM lugs, inspect for damage and replace if needed.

• What offset should I choose for aftermarket wheels?

  Offset depends on wheel width, brake package, and desired stance. One OEM example is ET 24 mm on an 18 x 7.5 wheel. Use the calculator to compare any new width and offset to your current setup and confirm inner and outer clearances.

• What tire size will keep my speedometer close to stock?

  Match overall tire diameter to your OEM value. For trims equipped with 245/45R20, the diameter is about 28.7 in. Aim for new sizes within about 3 percent of your stock diameter. Use the calculator to confirm.

• Will larger brakes on some trims affect wheel fitment?

  Yes. Larger calipers and rotors reduce inner barrel and spoke clearance. Always check brake clearance in the calculator and physically test-fit before mounting tires.

• What torque should I use on the lug nuts?

  Refer to the owner’s manual or Mopar service information for the exact torque spec for your trim. Re-torque after 50 to 100 miles.

• Do I need to service TPMS when changing wheels?

  Yes. Transfer your sensors or install compatible new ones. Some setups require a relearn or programming. Follow the TPMS tool and OEM instructions.

• What is backspacing, and why does it matter?

  Backspacing is the distance from the wheel mounting pad to the inner rim edge. It works with offset and width to determine inner clearance to the suspension. An example OEM backspacing is 4.69 in on an 18 x 7.5 wheel. Use the calculator to see how changes affect inner clearance.
