The following factory specifications are what we have on file for the 2008 Chevrolet Impala. This list may be partial and some values can vary by trim or package. Always confirm your exact equipment with the tire and loading label on the driver door jamb, the owner’s manual, or by contacting a Chevrolet dealer with your VIN. Use the on-page calculator to validate changes against your verified OEM size.

Notes: The wheel and tire data above likely represent different OEM trims. Many 2008 Impalas were equipped with 16 inch tires, while some trims used larger factory wheels. Verify your original size on the vehicle before using the calculator to compare changes.
The calculator on this page lets you compare a donor setup against your Impala and also test custom wheel and tire sizes. Follow these steps:
Use this checklist to avoid costly returns and safety issues. Confirm each item on your actual vehicle and with the calculator.
Several OEM configurations existed for the 2008 Impala. If your door label shows a 16 inch tire such as 225/60R16, a typical plus-size path for many sedans is plus-one to a 17 inch tire with a slightly lower aspect ratio, or plus-two to an 18 inch tire. Examples for calculator testing only:
Do not purchase based on examples. Always confirm your OEM size from the vehicle, then use the calculator to check diameter change, inner clearance to the strut and knuckle, and outer position relative to the fender. Keep offsets near your verified OEM value, and adjust width and offset together to maintain safe clearances. Finish with a physical test fit.
Prepare the vehicle on level ground with the parking brake set. Use proper jacking points and support the car on rated jack stands. Clean the hub face and the wheel mounting pad until bare metal for accurate seating. If using hub-centric rings, seat them fully on the wheel or hub per the ring design. Do not lubricate lug nut threads or seats unless the OEM service information specifies it. Install wheels by hand and snug the M12 x 1.5 lug nuts in a star pattern. Lower the vehicle and torque the lug nuts to the factory specification from the owner’s manual or service manual using a calibrated torque wrench. Re-torque after 50 to 100 miles of driving. Relearn or program TPMS sensors and verify no leaks at the valve stems and sensor seals. Check for rubbing at full steering lock in both directions and over bumps before regular driving.
What is the bolt pattern on a 2008 Chevrolet Impala?
It is 5x115 based on the information above. Always confirm on your specific car before buying wheels.
What center bore do I need for aftermarket wheels?
The vehicle hub bore is 70.3 mm. If your wheel bore is larger, use hub-centric rings that adapt the wheel bore to 70.3 mm.
What lug nut thread size does it use?
M12 x 1.5. Match the seat type to the wheel design and torque to the OEM specification from your manual.
Will 18 inch wheels fit my 2008 Impala?
Some trims used larger factory wheels. Fitment varies by brake package, wheel width, and offset. Verify your OEM size from the door label, then use the calculator to compare 18 inch options and complete a physical test fit.
What offset should I choose for aftermarket wheels?
We have an OEM reference of ET 52 mm for a 7.0 inch wheel. Stay close to your verified OEM offset and use the calculator to see how changes affect inner and outer clearance. Always test fit.
Can I run 5x114.3 wheels on a 5x115 car?
Do not mix bolt patterns unless an OEM source expressly approves it for your vehicle and hardware. It risks vibration and fastener stress.
Do I need new TPMS sensors?
If reusing your sensors, ensure they are compatible with the new wheels and that seals are replaced as needed. If buying new sensors, match them to your vehicle and complete the relearn procedure per the owner’s manual or with a TPMS tool.
How close should my new tire diameter be to stock?
Use the calculator to compare overall diameter. Many installers target a small variance to maintain speedometer accuracy and proper ABS and stability control operation. Confirm with a road test and a GPS speed check.
Where can I find my factory wheel and tire size?
Check the tire and loading label on the driver door jamb, the owner’s manual, or contact a Chevrolet dealer with your VIN. Use that verified size as the baseline in the calculator.
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.
