2008 Dodge Challenger Wheel Interchange

2008 Dodge Challenger Wheel Fitment And Interchange Guide | wheelinterchange.com

Known OEM Fitment For 2008 Dodge Challenger

The values below reflect one documented OEM configuration for the 2008 Dodge Challenger. Other trims or option packages may differ. If your vehicle’s equipment is different, confirm your exact specs using the on-page calculator and your owner’s manual or door-jamb tire placard.

Notes:

• Backspacing values can vary depending on how rim width is measured. If backspacing and offset do not seem to align, verify by measuring your wheel directly.
• If your trim differs, rely on the vehicle placard and OEM documentation, then use the calculator to compare any new setup to your baseline.

How To Use The Wheel Interchange Calculator

The calculator on wheelinterchange.com lets you compare a donor wheel and tire to your 2008 Dodge Challenger and test custom sizes before you buy.

• Set Installed on to 2008 Dodge Challenger. Use your OEM setup above as your baseline.
• Choose a donor vehicle or enter a Custom wheel size by rim diameter, rim width, and offset. You can also enter a Custom tire size by section width and aspect ratio.
• When you change rim diameter, the tire comparison updates overall tire diameter. Watch the tire diameter difference and keep it minimal to maintain speedometer accuracy and fender clearance.
• Use the inner clearance readout to ensure no contact with struts, springs, or brake lines. Use the outer poke readout to keep the tire inside the fender under compression and steering.
• Bolt pattern must be 5x115. If the donor is not 5x115, it is not a direct fit.
• Center bore must be at least 71.6 mm. Larger bores can be used with hub-centric rings that have a 71.6 mm inner diameter. Smaller bores will not fit.
• The calculator cannot confirm spoke-to-caliper clearance. Always test-fit one front wheel to verify caliper and barrel clearance, especially with aftermarket wheels.

Fitment Checklist Before You Buy

• Bolt pattern: 5x115 only. Do not substitute 5x114.3.
• Center bore: 71.6 mm hub required. If the wheel bore is larger, plan for hub-centric rings with 71.6 mm inner diameter.
• Thread size: M14 x 1.5. Use lug nuts that match both the thread and the wheel’s seat type. Do not mix conical, ball, or mag-seat styles.
• Width and offset: Use the calculator to confirm inner clearance to struts and outer poke relative to the fender. Measure your car and compare the calculator’s results.
• Brake clearance: Verify spoke and barrel clearance to your front calipers by test-fitting a wheel before mounting tires.
• Tire diameter: Keep overall diameter close to stock to avoid rubbing and speedometer error. Check the calculator’s tire diameter difference.
• Load rating: Wheel and tire load ratings must meet or exceed your vehicle’s axle loads. Check markings on the tire sidewall and wheel documentation.
• TPMS: If equipped, ensure sensor compatibility. Transfer your sensors or use compatible replacements and service kits.
• Hardware: Use the correct lug nut seat type and shank length where applicable. Verify full thread engagement.
• Return policy: Confirm the seller’s return terms in case the test fit fails.

Plus Sizing And Common Upgrades

Many owners explore wider wheels or alternative tire profiles. Since exact fit depends on offset, width, and tire choice, use the calculator to model changes and then verify on the car.

• Starting point: Enter your OEM 20x9 ET 26 with 245/45R20 as Installed on. This gives you a reliable baseline.
• Wider wheels: Increase rim width in 0.5 in steps in the Custom wheel size. Adjust offset until inner clearance stays safe and outer poke remains inside the fender. Confirm brake clearance by test fit.
• Staggered setups: If you are considering different rear widths, compare front and rear separately and keep tire diameter consistent front to rear unless you understand the impact on stability control and ABS.
• Tire selection: Use the Custom tire size to maintain similar overall diameter. Check section width vs rim width to avoid excessive stretch or sidewall bulge.
• Ride and handling: Lower profiles may sharpen steering feel but can increase impact harshness. Ensure your roads and suspension condition suit the change.

Installation Tips

• Prepare the car: Park on level ground, apply the parking brake, and use wheel chocks. Lift at approved jack points and support the vehicle with stands.
• Clean mounting faces: Remove rust and debris from the hub and wheel mounting pad so the wheel seats flat. A light film of anti-seize on the hub pilot can help prevent sticking, but keep it off the lug threads and seats unless your OEM procedure specifies otherwise.
• Hub-centric rings: If your wheels have a larger center bore, install rings with a 71.6 mm inner diameter that match your wheel’s outer bore. Rings should fit snugly without play.
• Hardware: Use M14 x 1.5 lug nuts that match the wheel’s seat type. Verify adequate thread engagement. Do not mix nut styles.
• Torque: Tighten lug nuts in a star pattern in gradual steps and torque to the OEM specification from your owner’s manual. Recheck torque after the first heat cycle or short drive.
• TPMS: If equipped, transfer sensors carefully or install compatible sensors. Use new TPMS service kits as needed and perform relearn procedures per OEM instructions.
• Final checks: Turn the steering lock to lock and compress the suspension if possible to check for fender and liner contact before road use.

FAQs

• What is the bolt pattern on the 2008 Dodge Challenger?

  5x115.

• What center bore does my 2008 Challenger require?

  71.6 mm. Wheels with a larger bore can be used with hub-centric rings that have a 71.6 mm inner diameter. Wheels with a smaller bore will not fit.

• Can I use 5x114.3 wheels on this car?

  This is not recommended. The 5x114.3 pattern does not match 5x115. Using the wrong pattern can stress studs and compromise safety.

• What is the OEM wheel and tire size?

  One documented OEM configuration is 20x9 ET 26 with 245/45R20 tires. Other factory setups may exist depending on trim or options. Verify yours by checking the door-jamb tire placard and owner’s manual.

• Do I need hub-centric rings?

  Only if your aftermarket wheel has a center bore larger than 71.6 mm. Choose rings with a 71.6 mm inner diameter and the correct outer diameter for your wheel.

• Will wheels from other Dodge or Chrysler models fit?

  Only if they match the 5x115 bolt pattern, have a compatible center bore, provide adequate brake and suspension clearance, and the offset works on your car. Use the calculator to compare and then test-fit.

• What lug nuts should I use?

  M14 x 1.5 thread is required. Match the seat type to your wheel design. Do not mix seat styles.

• What torque should I use on the lug nuts?

  Follow the OEM specification in your owner’s manual or service information. If you do not have access to it, contact a Dodge dealer for the correct value.

• How do I keep my speedometer accurate if I change tire size?

  Use the calculator to watch overall tire diameter difference. Keep the change minimal and verify clearance under steering and suspension movement.
