2009 Chevrolet Impala Wheel Interchange

2009 Chevrolet Impala Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2009 Chevrolet Impala

The details below reflect data points known for the 2009 Chevrolet Impala. Wheel and tire specifications can vary by trim and package. Some 2009 Impala models used 16 inch tire packages, while others used 18 inch wheel packages. Use the on-page calculator and your vehicle’s door-jamb tire placard or GM documentation to confirm your exact setup before you buy.

Important: The 18 inch wheel spec and the 225/60R16 tire spec come from different factory packages. Your Impala may differ. To confirm your original tire size, read the tire placard on the driver door jamb and compare with the calculator. To confirm original wheel size, check your build sheet, GM service information, or consult a dealer with your VIN.

How To Use The Wheel Interchange Calculator

• Choose Wheels from (donor vehicle) to enter the wheel and tire specs you want to try. This can be another vehicle or an aftermarket size.
• Set Installed on (your vehicle) to 2009 Chevrolet Impala so the tool compares against your car.
• Use Custom wheel size to change rim diameter, rim width, and offset. Use Custom tire size to change section width and aspect ratio.
• When you change rim diameter, the calculator updates the tire diameter in the comparison so you can see speedometer and clearance effects.
• Watch the inner clearance and outer poke changes. Make sure there is clearance to struts, control arms, fenders, and liners through full steering and suspension travel.
• Keep overall tire diameter as close as practical to your OEM tire so speedometer and gearing remain reasonable. The door-jamb placard is your baseline.
• If results are close, test fit a single wheel on the front and rear to confirm brake caliper and fender clearance before mounting tires.

Fitment Checklist Before You Buy

• Bolt pattern must be 5x115.
• Wheel center bore must be 70.3 mm or larger. If larger, use hub-centric rings to step down to 70.3 mm.
• Thread size is M12 x 1.5. Use lug nuts that match both the thread and the seat type required by the wheel manufacturer.
• Offset and backspacing must work with your brakes and suspension. Compare your choice to known OEM values in the calculator.
• Verify brake caliper spoke clearance and inner barrel clearance using a template or a physical test fit.
• Confirm load rating. Wheels and tires must meet or exceed the vehicle placard load index and GAWR.
• Match tire size, load index, and speed rating to at least the placard values. Do not underspec.
• TPMS: Plan to reuse compatible sensors or install and program sensors specified for the 2009 Impala. Follow GM service procedures.
• Check the seller’s return policy in case of unexpected interference or vibration.

Plus Sizing And Common Upgrades

Your 2009 Impala may have left the factory with either a 16 inch tire package or an 18 inch wheel package, depending on trim. Many owners consider plus-sizing to achieve a different look or tire selection. Use the calculator to:

• Model a move from a 16 inch package to an 18 inch wheel while choosing a tire with a sidewall that keeps overall tire diameter close to stock.
• Adjust offset to maintain inner clearance while avoiding excessive outer poke that could contact fenders on compression or steering.
• Evaluate width changes to keep the tire centered in the wheel well and away from struts and sway bar links.
• Choose a tire with appropriate load index and speed rating for your car and use case.

Because OEM sizes vary by trim, verify your starting point on the door-jamb placard, then iterate in the calculator until inner clearance and outer poke remain acceptable with your suspension geometry.

Installation Tips

• Inspect wheel studs and lug nuts. Replace any damaged parts before installing new wheels.
• Clean the hub face and wheel mounting pad. Remove rust and debris so the wheel seats flush and runs true.
• If the wheel bore is larger than 70.3 mm, install correct hub-centric rings to center the wheel on the hub.
• Hand start all lug nuts to prevent cross-threading. Do not lubricate threads unless an OEM procedure specifies it.
• Snug lugs in a star pattern, then torque in a star pattern to the OEM specification for your 2009 Impala. Refer to the owner’s manual or GM service information.
• Recheck torque after initial driving. Re-torque once the wheels have heat cycled and after a short mileage interval.
• After installation, turn the steering from lock to lock and drive over bumps at low speed to listen and check for rubbing.

Tools And Helpful Supplies

• Floor jack and jack stands rated for your vehicle
• 1/2 inch torque wrench
• 1/2 inch breaker bar
• M12 x 1.5 lug nuts that match your wheel’s seat type
• Hub-centric rings 70.3 mm to adapt larger wheel bores to the Impala hub
• Tire pressure gauge and inflator
• Wire brush for hub cleaning and brake caliper clearance template if available

FAQs

• What is the bolt pattern on the 2009 Chevrolet Impala?

  5x115. Wheels must match 5x115 for proper seating and safety.

• Can I install 5x114.3 wheels on a 2009 Impala?

  This is not recommended. Mixing bolt patterns can prevent proper seating and may cause vibration or fastener failure. Use 5x115 wheels.

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

  The vehicle hub bore is 70.3 mm. If your aftermarket wheel has a larger bore, use hub-centric rings to step down to 70.3 mm. If the wheel bore is smaller than 70.3 mm, it will not fit.

• What lug nuts does the 2009 Impala use?

  Thread size is M12 x 1.5. The seat type must match the wheel manufacturer’s specification. Always torque to the OEM spec listed in your owner’s manual or GM service information.

• Will 18 inch wheels fit my 2009 Impala?

  Some trims used 18 inch wheels from the factory. Fitment depends on your exact trim, brakes, and chosen tire size. Compare against the known OEM specs with the calculator and confirm using your door-jamb placard and a test fit.

• What is the stock tire size?

  One known OEM tire package is 225/60R16. Other trims used different sizes. Check your driver door-jamb placard for the tire size originally specified for your car.

• Do I need new TPMS sensors?

  If your current sensors are compatible and in good condition, you can often transfer them to new wheels. If replacing, use sensors specified for the 2009 Impala and follow GM programming procedures.
