2011 Chevrolet Impala Wheel Interchange

2011 Chevrolet Impala Wheel Fitment Guide

Known OEM Fitment For 2011 Chevrolet Impala

Factory equipment can vary by trim and package. The values below are reported for this model year, but specific wheel and tire sizes may differ on your vehicle. Confirm using your door jamb tire label, owner manual, RPO option codes, or the on-page calculator.

Note: The wheel and tire sizes shown above indicate that different trims likely shipped with different packages in 2011. If your vehicle differs, use the calculator on this page to compare what you have to potential replacements, and verify against OEM sources.

How To Use The Wheel Interchange Calculator

• Set Installed on to 2011 Chevrolet Impala so the calculator treats this as your vehicle.
• Choose Wheels from for a potential donor vehicle or enter its specs directly.
• Use Custom wheel size to enter rim diameter, width, and offset you want to test. Adjusting these will show inner and outer clearance changes compared to your current setup.
• Use Custom tire size to enter section width and aspect ratio. When you change rim diameter, the calculator updates tire diameter in the comparison so you can keep overall diameter close.
• Review outputs for:
  • Overall tire diameter difference and estimated speedometer change.
  • Inner clearance to suspension and outer poke relative to fender.
  • Backspacing changes vs. stock to assess spoke and caliper clearance.
• When the calculator shows a size that is close to your OEM diameter and clears inside and outside, you have a strong candidate. Always test fit before driving.

Fitment Checklist Before You Buy

• Bolt pattern must match exactly: 5x115.
• Center bore: 70.3 mm. If an aftermarket wheel has a larger bore, use hub-centric rings sized 70.3 mm inner to your wheel’s outer bore.
• Thread: M12 x 1.5. Use nuts or bolts that match both the thread and the wheel’s seat type. Do not mix ball-seat and cone-seat hardware.
• Offset and width: Compare inner clearance and outer poke in the calculator. Small offset changes can affect scrub and bearing load. Avoid extreme changes without confirming clearance on the car.
• Overall diameter: Keep tire overall diameter close to your door label size to protect ABS, traction control, and speedometer accuracy. A small variance is typically acceptable, but verify with the calculator.
• Brake and spoke clearance: Visually confirm that spokes clear calipers and that the barrel clears any brake hardware. Some designs with the same specs may still interfere.
• Load rating: Wheels and tires must meet or exceed the Impala’s axle loads. Check manufacturer ratings.
• TPMS: If equipped with direct TPMS, plan to transfer sensors or install compatible ones and perform a relearn procedure.
• Test fit each axle: Hand tighten, spin the wheel, and check for rubbing at full lock and over suspension travel before final install.

Plus Sizing And Common Upgrades

Many owners explore plus sizing to improve handling or aesthetics. Because factory wheel and tire packages for 2011 can vary by trim, use your own door label tire as the baseline in the calculator.

• Plus one or plus two: Increase rim diameter and select a proportionally lower tire aspect ratio so the overall tire diameter stays close to your baseline.
• Width changes: A wider wheel may need a different offset to keep inner clearance and outer poke reasonable. Validate with the calculator rather than relying on offset alone.
• Ride and protection: Larger wheels with lower-profile tires can ride firmer and are more susceptible to pothole damage. Consider your road conditions.
• Staggered setups: If considering staggered widths front and rear, confirm tire rotation limitations and stability control implications.

If your OEM label shows 225/60R16, you can use the calculator to search for alternate wheel diameters with tires that match overall diameter closely. Do not assume a size fits simply because another trim used it. Verify offset, width, and clearances on your vehicle.

Installation Tips

• Inspect hubs and clean the mating surfaces. Remove rust and debris so the wheel seats flat.
• If using hub-centric rings, ensure they are fully seated and not cracked or deformed.
• Verify lug nut seat type matches the wheel. Hand start all lugs to avoid cross-threading.
• Tighten in a star pattern in gradual steps to the torque specified in your owner’s manual or OEM service information.
• If using spacers, confirm they are hub-centric and that thread engagement meets minimum safe requirements per the spacer manufacturer.
• TPMS: Transfer sensors or install compatible ones if required. Perform the relearn procedure for your vehicle after installation.
• Re-torque after 50 to 100 miles and after any significant temperature swing.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M12 x 1.5 conical-seat lug nuts - only if they match your wheel’s seat type
• Hub-centric rings 70.3 mm ID - choose OD to match your aftermarket wheel bore
• TPMS relearn tool for GM

FAQs

• What is the bolt pattern for the 2011 Chevrolet Impala

  5x115.

• What is the center bore and thread size

  Center bore is 70.3 mm. Thread size is M12 x 1.5.

• The specs show 18 inch wheels and 225/60R16 tires. Which is correct

  Factory equipment varies by trim in this model year. Use your door jamb label, RPO codes, or the calculator to confirm what your specific car has. Treat the values listed here as reported OEM data points rather than a single universal configuration.

• Can I use 5x114.3 wheels on a 5x115 car

  No. Do not force a 5x114.3 wheel onto 5x115 studs. The mismatch can cause vibration, fastener stress, and loss of clamping force. Use wheels with the exact 5x115 pattern.

• What offset should I choose for aftermarket wheels

  The reported OEM offset is ET 52 mm, but final offset depends on the wheel width and design. Use the calculator to compare inner clearance and outer poke to your current setup, then test fit to confirm brake and fender clearance.

• Do I need hub-centric rings

  If your aftermarket wheel has a larger center bore than 70.3 mm, use rings that reduce it to 70.3 mm. If the wheel is already 70.3 mm, no ring is needed.

• What lug nuts do I need

  M12 x 1.5 thread is required. Match the seat type to the wheel design and torque to the value in your owner’s manual or OEM service manual.

• Will 18 inch wheels fit my 2011 Impala

  18 inch wheels are reported for this model year, but fitment depends on your trim and brake package. Use the calculator to compare diameter, width, and offset to your current setup, then verify clearance with a test fit.

• What about TPMS when changing wheels

  If your car uses direct TPMS, you will need compatible sensors installed or transferred. After installation, perform the TPMS relearn per the owner’s manual or OEM procedure.
