These are vehicle-year records whose recorded OEM ranges overlap this 2017 Chevrolet Impala. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 29 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -1.67 mm, inner change -4.68 mm. This uses aggregated width/offset ranges, not a specific wheel.

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.

The values below are the fitment data currently available for this model year on wheelinterchange.com. Some trims and option packages may differ. If a value is not listed for your exact trim, confirm it using the on-page calculator, your door jamb tire placard, the owner’s manual, or a GM parts catalog by VIN.
| Spec | Value | Notes |
|---|---|---|
| Bolt pattern | 5x120 | 5 studs on a 120 mm pitch circle |
| Center bore | 66.9 mm | Hub diameter. Aftermarket wheels with a larger bore may need rings |
| Thread size | M14 x 1.5 | Verify lug seat style matches your wheel |
| Rim diameter | 20 in | Shown for at least one OEM package. Other OEM diameters may exist |
| Rim width | 8.5 in | Shown for at least one OEM package |
| Wheel offset | ET 45 mm | Shown for at least one OEM package |
| Backspacing | 6.02 in | Approximate, based on listed width and offset |
| Tire size example | 235/50R18 | Listed OEM tire example. Tire sizes vary by trim and wheel diameter |
Note: The presence of both a 20x8.5 wheel and a 235/50R18 tire in the known data indicates multiple OEM packages across trims. Do not mix wheel and tire sizes without confirming overall diameter, brake clearance, and fender clearance.
The calculator compares two setups: Wheels from a donor vehicle and Wheels installed on your vehicle. You can also test a custom wheel and tire size.
Many owners explore 19 or 20 inch wheels for appearance and handling. The 2017 Impala has been offered with multiple OEM packages, and our known data includes at least one 20x8.5 ET45 wheel and a separate 235/50R18 tire example. Because sizes vary by trim and package, always:
If you are uncertain which OEM size your Impala shipped with, confirm by VIN at a GM dealer before purchasing wheels or tires.
What is the bolt pattern for the 2017 Chevrolet Impala?
5x120. Always verify on your specific trim and compare in the calculator before buying.
What center bore do I need?
66.9 mm hub bore. Wheels with a larger bore can be used with hub-centric rings. Smaller bores will not fit.
What is the lug nut thread size?
M14 x 1.5. Match the lug seat type to the wheel design and torque to the value in the owner’s manual.
Will wheels from another GM with 5x120 fit my Impala?
Only if bolt pattern, center bore, offset, brake clearance, and load rating are correct. Use the calculator and verify all dimensions, not just PCD.
Can I run 20 inch wheels?
At least one OEM 20x8.5 ET45 package exists in the known data, but fitment can vary by trim and brake package. Model your setup in the calculator and confirm clearances on your car.
What tire size should I choose when plus sizing?
Use the calculator to keep overall diameter close to OEM. Start from your door placard size and target within about 2 to 3 percent change.
Do I need hub-centric rings with aftermarket wheels?
If the aftermarket wheel bore is larger than 66.9 mm, yes. Choose rings that reduce the wheel bore to 66.9 mm.
Will 5x120.65 or 5x4.75 wheels work?
No. Those are different patterns and should not be used.
What is the correct torque spec for the lug nuts?
Torque varies by wheel and trim. Use the value in the 2017 Impala owner’s manual or OEM service information and recheck after 50 to 100 miles.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
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.
