The 2012 Civic uses 15-inch rims on the LX, 16-inch rims on the EX and EX-L, and 18-inch rims on the Si; all factory wheels share a 4x100 bolt pattern and a 64.1 mm center bore. For aftermarket rims, make sure the width and offset are compatible to avoid brake or body clearance issues.
In detail, the 2012 Honda Civic (ninth generation) offered three main wheel sizes tied to trim levels. This guide outlines the factory sizes and what you should know when selecting aftermarket rims for your car.
Factory wheel sizes by trim
Below are the standard sizes by trim and the corresponding tires, along with the key fitment notes you should keep in mind when swapping wheels.
LX trim (base model) wheel size
The LX typically wears 15-inch wheels (stock), with 195/65R15 tires. This uses a 4x100 bolt pattern and a 64.1 mm center bore. When shopping for 15-inch aftermarket wheels, aim for about 15x6.0–15x6.5 with an offset that keeps the tire inside the fender clearance.
- Rim size: 15 inches
- Tire size (stock): 195/65R15
- Bolt pattern: 4x100
- Center bore: 64.1 mm
Concluding: LX wheels are 15 inches; many 15" aftermarket wheels will fit, but verify offset and contact with the calipers or struts.
EX/EX-L trim wheel size
EX and EX-L models come with 16-inch alloy wheels, commonly 16x6.5 or similar, paired with 205/55R16 tires. They use the same bolt pattern and center bore as the LX. When replacing, ensure your chosen wheels maintain similar width and an offset that clears the brakes and suspension.
- Rim size: 16 inches
- Tire size (stock): 205/55R16
- Bolt pattern: 4x100
- Center bore: 64.1 mm
Concluding: EX/EX-L wheels are 16 inches; aftermarket options should preserve compatibility with the 4x100 pattern and appropriate offset to avoid interference.
Si trim wheel size
The Civic Si uses larger 18-inch wheels (often 18x7.5) with 235/40R18 tires. This trim also uses the 4x100 bolt pattern and 64.1 mm center bore. If upgrading, check that the offset fits without rubbing on the brakes or inner fenders, and consider brake clearance.
- Rim size: 18 inches
- Tire size (stock): 235/40R18
- Bolt pattern: 4x100
- Center bore: 64.1 mm
Concluding: Si uses 18-inch rims; ensure proper offset/width to maintain brake clearance and alignment when purchasing aftermarket wheels.
Summary
In short, for a 2012 Honda Civic, factory wheel options are 15 inches (LX), 16 inches (EX/EX-L), and 18 inches (Si). All trims use a 4x100 bolt pattern and a 64.1 mm center bore. When selecting aftermarket rims, stay within suitable width and offset ranges to preserve clearance and accuracy of the speedometer/TPMS, and consult a professional or OEM-fitment guides for your exact configuration if in doubt.
