2019 Chevrolet Impala Wheel Interchange

2019 Chevrolet Impala Wheel Interchange, Specs, and Upgrade Guide

Known OEM Fitment For 2019 Chevrolet Impala

The values below are the known specs provided for this vehicle. Trims and packages can vary. If anything is unclear or seems to conflict, verify against the driver door jamb tire placard, the owner’s manual, or the on-page calculator before purchasing.

Note: The data above reflects what is available. Factory wheel and tire sizes can vary by trim. If your door jamb sticker shows a different size, treat that as your stock baseline and use the calculator to compare changes.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a donor wheel and tire setup to your 2019 Chevrolet Impala, and also test custom sizes. Follow these steps:

• Set Installed on (your vehicle) to 2019 Chevrolet Impala.
• If you are comparing wheels from another vehicle, enter that under Wheels from (donor vehicle). Otherwise, use Custom wheel size and Custom tire size.
• Enter your baseline OEM size from the door placard or from the Known OEM Fitment table above.
• Adjust Custom wheel size: change rim diameter, width, and offset to what you plan to buy.
• Adjust Custom tire size: set section width and aspect ratio. When you change rim diameter, the calculator updates tire diameter in the comparison so you can see ride height and speedometer effects.
• Review results for inner clearance to suspension/brakes, outer poke vs fender, overall tire diameter change, and speedometer difference.
• Aim for minimal diameter change (commonly within about 3%) and verify there is physical clearance through full steering lock and suspension travel.

Fitment Checklist Before You Buy

• Bolt pattern: new wheels must be 5x120.
• Center bore: 66.9 mm hub on the vehicle. If the wheel’s center bore is larger, plan for hub-centric rings to 66.9 mm. If smaller, the wheel will not fit.
• Thread size and hardware: M14 x 1.5. Confirm lug seat type (conical/ball/mag) with the wheel manufacturer. Match hardware to the wheel design.
• Offset and backspacing: use the calculator to compare to the OEM ET 45 reference and confirm both inner clearance and outer fender position.
• Brake and spoke clearance: test fit to verify caliper-to-spoke clearance.
• Tire overall diameter: keep total diameter close to your OEM baseline to help maintain ABS, traction control, and speedometer accuracy.
• Load and speed rating: tires must meet or exceed the OEM ratings on your door placard.
• TPMS: confirm sensor compatibility and plan for relearn/programming after installation.

Plus Sizing And Common Upgrades

Plus sizing increases wheel diameter and typically lowers tire sidewall height to keep overall tire diameter close to stock. If your placard shows 235/50R18 (as provided above for at least one factory configuration), you can:

• Use the calculator to raise rim diameter and then reduce tire aspect ratio until overall diameter change is minimal.
• Compare offsets so inner clearance to the strut and outer poke at the fender remain safe.
• For daily driving and winter use, many owners prefer narrowing the tire slightly for better snow traction. Always match or exceed OEM load rating.
• Staggered setups are generally not recommended on front wheel drive sedans due to rotation limitations and handling balance changes. If you do consider it, validate clearances at both axles and keep overall diameters matched.

Because factory sizes vary by trim, start with your door placard as the baseline and use the calculator to dial in an upgrade that preserves clearance and diameter targets.

Installation Tips

• Test fit one front corner first. Hand-spin to check for caliper, knuckle, and fender liner interference. Turn lock-to-lock and compress the suspension if possible.
• Clean the hub face and center pilot. Remove rust and debris to ensure the wheel seats flush. Do not lubricate lug nut threads unless the OEM procedure specifies it.
• If using hub-centric rings, install them fully seated on the wheel before mounting.
• Tighten lug nuts in a star pattern and torque to the factory specification from Chevrolet service information for the 2019 Impala.
• Re-torque after 50 to 100 miles of driving.
• Perform TPMS relearn/programming after installation and set tire pressures to the door placard values.

FAQs

• What is the 2019 Chevrolet Impala bolt pattern?

  5x120. Wheels must match this pattern to mount correctly.

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

  The vehicle hub bore is 66.9 mm. If your aftermarket wheel has a larger center bore, install hub-centric rings to 66.9 mm. A smaller bore will not fit.

• What lug nuts does it use?

  Thread size is M14 x 1.5. The lug seat type depends on the wheel design, so confirm with the wheel manufacturer. Torque to the OEM specification from Chevrolet service information.

• Will 5x120.65 (5x4.75) wheels fit my Impala?

  No. 5x120 and 5x120.65 are not interchangeable. Do not attempt to force-fit mismatched bolt patterns.

• Can I run 20 inch wheels on my 2019 Impala?

  A 20 inch rim diameter is listed among the provided OEM specs, and some trims may have been equipped differently. Verify your baseline on the door placard, then use the calculator to confirm offset, clearance, and tire diameter before purchasing.

• What was the stock tire size?

  A 235/50R18 package is provided among the known specs. Trim levels may differ, so confirm your exact OEM size on the door jamb placard and use that as your comparison baseline.

• Do I need spacers or longer studs?

  Only if clearance checks show interference and a properly engineered spacer is required. If spacers are used, they must be high quality and hub-centric, and appropriate hardware length is required. Re-check torque after installation.

• Can I reuse my factory TPMS sensors?

  You can typically reuse OEM-style sensors or install compatible replacements. After mounting, perform the TPMS relearn for your 2019 Impala and confirm system operation.

• What offset should I choose for aftermarket wheels?

  Use the provided OEM ET 45 as a reference point and compare alternatives in the calculator. Verify inner clearance to the suspension and outer position relative to the fender on your specific trim.
