Dataset suggestionHub-centric rings ≈ 70.3 → 66.9 mm – not a verified installation requirement.
Hub-centric rings of about 70.3 → 66.9 mm mm may be relevant if the wheel bore is larger than the hub; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.

2016 Chevrolet Impala Wheel Fitment Guide
Known OEM Fitment For 2016 Chevrolet Impala
The data below reflects OEM specifications observed for certain 2016 Chevrolet Impala trims. Some values can vary by trim, package, or wheel option. If your vehicle’s build differs, use the calculator on this page and confirm against your owner’s manual, the driver’s door-jamb label, and OEM parts catalogs before buying.

Notes:
The 20x8.5 ET45 wheel entry and the 235/50R18 tire entry indicate multiple OEM configurations may exist across trims. Do not assume they came together on the same car. Check your build details and measure if needed.
If your OEM or replacement wheel has a center bore larger than 66.9 mm, use hub-centric rings sized to 66.9 mm at the vehicle side.
Calculated overall diameter for 235/50R18 is approximately 27.3 inches. Use this as a reference when evaluating plus-sized options.
How To Use The Wheel Interchange Calculator
The calculator lets you compare a donor wheel/tire setup against your Impala and test custom sizes. Follow these steps:
Enter Wheels from (donor vehicle): Input the donor’s wheel diameter, width, and offset, plus tire section width and aspect ratio if tires are included.
Enter Installed on (your vehicle): Select 2016 Chevrolet Impala. If your exact OEM size differs from the values above, adjust to match your door-jamb label or OEM documentation.
Custom wheel size: Try alternative rim diameter, width, and offset. The calculator will recalculate inner and outer clearance, track change, and poke.
Custom tire size: Enter tire section width and aspect ratio. The tire diameter updates automatically when you change rim diameter, so you can keep overall diameter close to stock.
Review results: Aim to keep overall tire diameter within about ±3% of your stock reference (approximately 27.3 inches based on 235/50R18) to limit speedometer error and maintain ABS/traction control behavior.
Check clearances: Ensure adequate inner clearance to the strut/spring perch, brake calipers, and fender liners, and reasonable outer poke relative to the fender.
Fitment Checklist Before You Buy
Confirm bolt pattern: 5x120.
Confirm center bore: 66.9 mm. If wheels have a larger bore, plan for hub-centric rings to 66.9 mm.
Confirm thread size: M14 x 1.5. Verify lug nut/bolt seat type matches the wheel design. Do not mix conical, ball, or mag seats.
Measure brake/caliper clearance: Test-fit if possible. Spokes and barrel profile vary by wheel model.
Offset and width: Use the calculator to verify inner clearance and outer poke. Small offset changes can have big effects on fender and strut clearance.
Tire diameter: Keep near your stock reference diameter to help maintain speedometer accuracy and prevent rubbing.
Load and speed ratings: Tires must meet or exceed OEM load index and speed rating. Check your door-jamb label and owner’s manual.
TPMS: Plan to transfer, service, or replace sensors. Confirm frequency/protocol compatibility for your year.
Backspacing: The listed 6.02 inches corresponds to the provided 20x8.5 ET45 entry, but always measure or confirm with the wheel manufacturer.
Plus Sizing And Common Upgrades
Many owners explore 19 or 20 inch wheels for appearance or handling. Because OEM configurations vary by trim, do not assume any upgrade will fit without verification. Use the calculator to:
Target a total tire diameter close to approximately 27.3 inches based on the listed 235/50R18 reference, staying within about ±3%.
Balance width and offset to avoid inner rub on struts and outer fender contact during turns and suspension compression.
Evaluate steering feel and ride quality trade-offs as you move to lower-profile tires.
Always confirm final choices with physical test-fit and OEM documentation before purchasing.
Installation Tips
Preparation: Park on level ground, set the parking brake, and chock wheels. Use jack stands at proper points. Never rely solely on a jack.
Hub mating surfaces: Clean rust and debris from the hub face and wheel mounting pad with a nylon or brass brush. The surfaces must be flat and clean.
Hub-centric rings: If your wheel bore is larger than 66.9 mm, install appropriate rings to 66.9 mm for a vibration-free ride.
Lug hardware: Verify M14 x 1.5 threads and correct seat type. Do not lubricate studs or nuts unless the OEM service manual explicitly instructs it.
Torque: Hand-start all lugs, snug in a star pattern, then final torque in stages with a calibrated torque wrench per the Chevrolet service specification for your exact trim. Re-torque after 50–100 miles.
TPMS: Move sensors as needed. Use new seals/cores when servicing and perform relearn procedures as specified for the 2016 Impala.
Road test: Check for vibration, rubbing on lock-to-lock turns, and fender clearance over bumps. Re-check torque and inspect after the first drive.
What is the bolt pattern for the 2016 Chevrolet Impala?
5x120 as listed above. Verify on your vehicle before ordering.
What center bore do I need?
66.9 mm at the vehicle hub. If your wheels have a larger bore, use hub-centric rings sized down to 66.9 mm.
What is the correct thread size?
M14 x 1.5. Confirm the lug seat type matches your wheel design.
Why do I see both a 20-inch wheel and an 18-inch tire listed?
Different OEM configurations can exist across trims and options. Use your door-jamb label, owner’s manual, and the on-page calculator to confirm what applies to your specific vehicle.
How close should my new tire diameter be to stock?
As a general guideline, keep within about ±3% of your stock reference diameter. Based on 235/50R18, that reference is approximately 27.3 inches.
Will 20x8.5 ET45 wheels fit my Impala?
That specification appears in the OEM data for some trims. Fitment can vary by brakes, suspension, and bodywork. Verify inner and outer clearances with the calculator and perform a physical test-fit.
What torque should I use on the lug nuts?
Refer to the Chevrolet service information for your exact trim and wheel package. Do not guess; use a calibrated torque wrench and re-check after 50–100 miles.
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
