2018 Dodge Challenger Wheel Interchange

2018 Dodge Challenger Wheel Interchange, Specs, and Upgrade Guide

Known OEM Fitment For 2018 Dodge Challenger

The values below reflect one verified OEM wheel and tire package for the 2018 Dodge Challenger. Other trims and appearance or performance packages may differ. If any item is unknown for your specific VIN or trim, use the on-page calculator and confirm against your owner’s manual or OEM service information before purchasing.

Note: If your 2018 Challenger has different factory wheels or a staggered setup, specifications can vary by trim. Verify your exact setup by VIN, door-jamb label, or OEM documentation.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a donor wheel and tire to your Challenger’s setup, and it updates tire diameter as you change rim diameter.

• Pick Wheels from - choose the donor vehicle or enter its wheel and tire specs.
• Pick Installed on - select 2018 Dodge Challenger or enter your current specs.
• Custom wheel size - adjust rim diameter, width, and offset to test fit ideas.
• Custom tire size - enter section width and aspect ratio. When you change rim diameter, the calculator updates the tire’s overall diameter in the comparison so you can keep close to stock.
• Review key results - inner clearance to suspension and brakes, outer poke vs fender, overall tire diameter change, speedometer variance, backspacing, and offset differences.
• Confirm critical interfaces - bolt pattern 5x115, center bore 71.5 mm, and M14 x 1.5 thread. If the donor wheel has a larger center bore, plan for hub-centric rings sized to 71.5 mm at the vehicle side.
• Brake clearance - large factory or aftermarket brakes may need specific spoke designs and offsets. Always test-fit or use a template from the wheel maker when available.

Fitment Checklist Before You Buy

• Match bolt pattern exactly to 5x115. Do not rely on near-miss patterns.
• Center bore must seat on 71.5 mm. Use hub-centric rings if the wheel’s bore is larger. Do not force a smaller bore onto the hub.
• Thread size is M14 x 1.5. Use correct-seat lug nuts or bolts specified for the wheel design. Verify that the studs or bolts provide full thread engagement per OEM guidance.
• Offset and backspacing - use the calculator to compare inner clearance to struts, control arms, and brake components, and to check outer poke vs fenders.
• Tire overall diameter - keep total diameter close to stock to minimize speedometer error and avoid rubbing. Use the calculator’s diameter and speed readings.
• Load rating - wheels and tires must meet or exceed the vehicle’s axle and GVWR requirements.
• TPMS - plan to transfer sensors or install compatible replacements, then perform the relearn procedure per the manual.
• Test fit - spin the wheel by hand on the hub to verify brake and suspension clearance before mounting tires.

Plus Sizing And Common Upgrades

Many Challenger owners explore plus-one or plus-two options. Actual fitment varies by trim, brake size, suspension, and alignment. Use these guidelines:

• Keep overall tire diameter close to the 235/55R18 baseline of about 28.2 in to preserve speedometer accuracy and clearance.
• As wheel diameter increases, select tire aspect ratios that maintain similar overall diameter. The calculator will update diameter as you change rim size.
• Wider wheels or tires require careful offset selection. Use the calculator to balance inner clearance and outer fender poke.
• If your car came with a staggered setup, keep front and rear rolling diameters closely matched to avoid driveline or ABS issues. Verify your trim’s factory configuration with OEM sources if unsure.
• Always confirm brake caliper and spoke clearance when moving to different diameters or designs.

Installation Tips

• Prepare the hub - clean rust and debris from the 71.5 mm hub lip and rotor hat so the wheel seats flush. Use only a light, OEM-approved anti-seize on the hub face if specified by the manufacturer.
• Dry fasteners - unless your service manual states otherwise, install lug nuts dry and clean. Do not lubricate studs or seats.
• Centering - if using aftermarket wheels with larger bores, install correct hub-centric rings and verify a snug, concentric fit before tightening lugs.
• Tighten in a star pattern in stages, using a calibrated torque wrench set to the OEM spec for your trim. If you do not know the spec, consult the owner’s manual or OEM service information.
• Re-torque after 50 to 100 miles of driving and after any significant temperature swings.
• Check for rubbing on full lock and over bumps. Inspect inner liners, brake hoses, and fender edges.

FAQs

• What is the 2018 Challenger bolt pattern?

  5x115.

• Can I use a 5x114.3 wheel on a 5x115 hub?

  It is not recommended. Use the exact 5x115 pattern to avoid stress on studs and improper seating.

• What center bore do I need?

  71.5 mm at the vehicle hub. If your wheel has a larger bore, use hub-centric rings sized to 71.5 mm on the vehicle side and your wheel’s bore on the other side.

• What lug nut thread size does the 2018 Challenger use?

  M14 x 1.5. Ensure the lug seat type matches your wheel design.

• What is the stock wheel offset for the provided OEM package?

  24 mm on a 18x7.5 in wheel, with about 4.69 in backspacing. Other trims may differ. Verify for your VIN if uncertain.

• Will 20 inch wheels fit my 2018 Challenger?

  Fitment can vary by trim, brakes, and alignment. Use the calculator to maintain a similar overall tire diameter, check inner and outer clearances, and confirm brake caliper clearance. Verify against OEM sources before buying.

• How close should I keep tire diameter to stock?

  Stay close to the OEM baseline of about 28.2 in from 235/55R18 to minimize speedometer error and rubbing. Use the calculator’s diameter and speed error outputs.

• Do I need new TPMS sensors?

  You can transfer your existing sensors if compatible with the new wheels, or use compatible replacements. Perform the relearn per the owner’s manual.

• What torque should I use on the lug nuts?

  The torque spec can vary. Refer to your owner’s manual or OEM service information for the exact value for your trim and wheel type.

• How do I check offset changes safely?

  Enter the new rim width and offset in the calculator. Confirm that inner clearance to struts and brakes remains safe and that outer poke does not exceed your fender limits.

Tip: If any dimension for your specific 2018 Dodge Challenger is unknown or differs from the values above, verify with the on-page calculator, your owner’s manual, OEM service data, or a dealer parts department using your VIN.
