2017 Chevrolet Impala Wheel Interchange

2017 Chevrolet Impala Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2017 Chevrolet Impala

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.

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.

How To Use The Wheel Interchange Calculator

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.

• Select Donor vehicle to load its wheel specs. Select Installed on to load your 2017 Chevrolet Impala baseline.
• Use Custom wheel size to adjust rim diameter, width, and offset. The visual shows inner and outer clearance changes in millimeters and inches.
• Use Custom tire size to change section width and aspect ratio. When you change rim diameter, the tool also updates the compared tire’s overall diameter so you can see speedometer impact and fender gap changes.
• Target overall tire diameter change within about 2 to 3 percent for street use. Larger changes may affect ABS, traction control, and gearing.
• Watch two clearances: Inner clearance to strut or spring perch and outer poke toward the fender lip. Maintain positive brake caliper clearance.
• If any OEM value is unknown for your trim, pull it from your tire placard, owner’s manual, or a GM parts lookup by VIN, then enter it into the calculator to model upgrades.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x120 for direct fit. Do not install 5x120.65 or 5x4.75 as they are not the same.
• Center bore: Hub is 66.9 mm. Use hub-centric rings if the wheel bore is larger. Do not use wheels with a bore smaller than 66.9 mm.
• Thread and seat: Lugs are M14 x 1.5. Match the seat type to the wheel design (commonly conical or ball seat). Do not reuse mismatched lug nuts.
• Offset and backspacing: Compare ET and backspacing in the calculator. Ensure inner clearance to suspension and brakes and avoid excessive outer poke.
• Brake caliper clearance: Test with a template if available or a physical test fit. Spoke design matters as much as diameter.
• Tire diameter: Keep overall diameter close to OEM to protect ABS and speedometer accuracy. Use the calculator’s diameter comparison.
• Load rating: Wheel and tire load ratings should meet or exceed the Impala’s GAWR. Verify on manufacturer spec sheets.
• TPMS: Plan to transfer or program new sensors that match your vehicle. Verify compatibility by VIN.
• Fender and liner clearance: Check at full steering lock and over bumps. Pay attention to front bumper tab areas and rear inner liners.

Plus Sizing And Common Upgrades

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:

• Start with your exact OEM wheel and tire from the door placard or VIN-sourced parts data.
• Use the calculator to model a plus size, keeping overall tire diameter change within about 2 to 3 percent.
• Adjust wheel offset so inner clearance is safe while outer poke remains inside the fender.
• Select tire widths that maintain adequate strut and fender clearance and match the chosen wheel width.

If you are uncertain which OEM size your Impala shipped with, confirm by VIN at a GM dealer before purchasing wheels or tires.

Installation Tips

• Test fit every wheel on the hub before mounting tires. Confirm hub fit, caliper clearance, and stud engagement.
• Clean hub faces and wheel mounting pads. Remove rust and debris to prevent vibration.
• If using hub-centric rings, seat them fully on the wheel and verify a snug fit on the 66.9 mm hub.
• Hand start all lug nuts, then snug in a star pattern. Final torque to the value in your owner’s manual. Recheck torque after 50 to 100 miles.
• Transfer TPMS sensors or install compatible sensors and complete the relearn procedure recommended by GM.
• After changing sizes or offsets, get a four-wheel alignment and check for rubbing at full lock and over bumps.
• Avoid anti-seize on studs unless specified by the manufacturer. It can alter clamping force.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M14x1.5 lug nuts that match your wheel seat type
• 66.9 mm hub-centric rings for aftermarket wheels with larger bores
• Tire pressure gauge for post-install checks

FAQs

• 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.
