2014 Chevrolet Impala Wheel Interchange

2014 Chevrolet Impala Wheel Interchange, Specs, and Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2014 Chevrolet Impala

The values below are what we have for this model year. They may reflect different trims or option packages. If a value on your car differs, confirm it against your door-jamb placard, owner’s manual, and the on-page calculator before buying wheels or tires.

Notes:

• The wheel and tire entries above come from different reported OEM setups for the 2014 Impala. Some trims used 18-inch tires; other trims/wheel packages may differ. Do not assume all values shown belong to the same package.
• Published backspacing figures can vary based on how rim width is measured. Use the calculator to cross-check offset and backspacing for your exact wheel width.
• If anything is unclear for your trim, verify with your VIN at a Chevrolet dealer or in the GM service information.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a donor wheel/tire to what will be installed on your 2014 Impala, and it updates tire diameter when you change rim diameter.

• Set “Installed on (your vehicle)” to 2014 Chevrolet Impala.
• For a baseline, select your current OEM wheel/tire in “Wheels from (donor vehicle)” or manually enter your known sizes. If your placard shows 235/50R18, use that to anchor overall diameter.
• Adjust “Custom wheel size” (rim diameter, width, and offset). The tool will calculate inner/outer position changes relative to your baseline.
• Adjust “Custom tire size” (section width and aspect ratio). When you change rim diameter, the calculator will update tire diameter in the comparison so you can match or safely deviate from OEM overall diameter.
• Review:
  • Overall tire diameter difference compared to stock.
  • Inner clearance to suspension/brakes and outer “poke” toward the fender.
  • Speedometer change, if any.
• Iterate until tire diameter and clearances are acceptable, then confirm physically on the car before driving.

Fitment Checklist Before You Buy

• Bolt pattern: Your Impala uses 5x120. A 5x120.7 (5x4.75) wheel is not the same and should not be forced on.
• Center bore: 66.9 mm. If a wheel’s center bore is larger, use hub-centric rings to 66.9 mm. If it is smaller, the wheel will not seat.
• Threads: M14 x 1.5. Use the correct nut/seat style for the wheel design (cone, ball, or mag) and correct shank length if applicable.
• Offset and width: Use the calculator to compare the candidate wheel (for example, a 20 x 8.5 ET45 reported example) against your OEM setup. Ensure adequate inner and outer clearance for suspension, brake calipers, and fenders.
• Overall tire diameter: Aim to keep overall diameter close to your OEM tire to maintain speedometer accuracy and avoid rubbing. If your placard lists 235/50R18, its overall diameter is roughly 27.3 inches; target a similar diameter when upsizing wheels.
• Brake clearance: Check spoke-to-caliper and barrel clearance. Test-fit a front wheel since fronts are usually the tightest.
• Load and speed rating: Replacement tires and wheels must meet or exceed OEM load and speed ratings.
• TPMS compatibility: Verify sensor type and frequency for your VIN. Reuse or replace sensors as needed and perform relearn after installation.
• Backspacing: If you work in backspacing, re-check against offset and width in the calculator to ensure consistency.

Plus Sizing And Common Upgrades

This model year has been reported with both 18-inch and larger wheel packages. We show a 20 x 8.5 ET45 wheel example and a 235/50R18 tire example in the known data. Trims vary, so confirm your baseline first.

• Plus sizing approach:
  • Identify your OEM tire size from the door placard or manual.
  • Use the calculator to find a 19-inch or 20-inch tire whose overall diameter closely matches your OEM tire.
  • Adjust offset and width to maintain safe inner/outer clearances.
• Ride and steering:
  • Larger wheels with lower-profile tires can sharpen steering but may ride firmer and be more prone to impact damage.
  • Wider wheels can improve grip but demand more clearance–check at full lock and over bumps.
• When in doubt, test-fit and cycle the suspension (turn lock-to-lock and compress the suspension) before finalizing tires.

Installation Tips

• Prepare: Park on level ground, chock wheels, and use jack stands. Clean hub faces and the wheel’s mounting pad so they’re free of rust and debris.
• Hub-centric: If the aftermarket wheel’s center bore is larger than 66.9 mm, install suitable rings so the wheel centers on the hub.
• Lug hardware: Verify M14 x 1.5 thread and the correct seat style for your wheels. Do not mix seat styles.
• Tightening: Hand-thread lug nuts, snug in a star pattern, then torque to the OEM specification from your owner’s manual or service information. Do not use an impact gun for final torque.
• TPMS: Transfer or install sensors, replace service kits as needed, and perform the TPMS relearn.
• Clearance check: After mounting, turn lock-to-lock and check inner liners, struts, and brake lines. Load the car and re-check over bumps.
• Re-torque: Re-check lug torque after 50–100 miles and again after any severe pothole impact.

Tools And Helpful Supplies

• 1/2 inch torque wrench
• M14 x 1.5 lug nuts (correct seat style for your wheel)
• 66.9 mm hub-centric rings (only if your new wheel bore is larger)
• Tire pressure gauge

FAQs

• What is the bolt pattern for the 2014 Chevrolet Impala?

  5x120.

• What center bore does it use?

  66.9 mm. Use hub-centric rings if your new wheel has a larger bore.

• What lug thread size do I need?

  M14 x 1.5. Match the correct seat style to your wheel design.

• Will a 5x120.7 (5x4.75) wheel fit my Impala?

  No. 5x120 and 5x120.7 are different. Do not attempt to force mis-matched patterns.

• What offset works on this car?

  We show a reported example of ET45 on an 8.5-inch-wide wheel. Actual safe offset depends on your wheel width, brake package, and fender clearance. Compare your candidate setup in the calculator and physically test-fit.

• My placard shows 235/50R18. How do I choose a 19 or 20 inch tire?

  Use the calculator to target a similar overall diameter to your OEM size (a 235/50R18 is roughly 27.3 inches overall). Adjust section width and aspect ratio until the new tire diameter and clearances look acceptable.

• Do I need new lug nuts?

  You can often reuse OEM nuts with OEM-style wheels. For aftermarket wheels, match thread (M14x1.5) and the correct seat type. Never mix seat styles.

• Do I need hub-centric rings?

  Only if the new wheel’s center bore is larger than 66.9 mm. Rings make the wheel hub-centric and help prevent vibration.

• Is the backspacing value of 6.02 inches exact for my car?

  That number is a reported example and may vary with wheel width and how it’s measured. Use the calculator to reconcile offset and backspacing for your chosen wheel size.

• What torque should I use on the lug nuts?

  Use the OEM lug torque from your owner’s manual or Chevrolet service information for your trim. Do not guess; verify and use a calibrated torque wrench.
