The stock tire sizes depend on trim: LX/DX 195/65R15; EX/EX-L 205/55R16; Hybrid 205/60R16; Si 235/40R18. Always verify on the door placard or in the owner's manual.
In 2009, Honda offered several Civic trims in the United States with distinct wheel-and-tire packages. Base models rode on smaller 15-inch rims, mid-range trims moved to 16-inch wheels, and the performance-oriented Si rode on 18-inch wheels. The Hybrid paired a 16-inch wheel with a taller tire profile. This article outlines the typical OEM sizes and notes where variations might occur.
Standard tire sizes by trim
The following are the commonly installed stock tire sizes for the U.S.-spec 2009 Civic, organized by trim family. If your model has aftermarket wheels or a different factory option, sizes may vary; always confirm with the placard on the door jamb.
- DX/LX: 195/65R15
- EX/EX-L: 205/55R16
- Hybrid: 205/60R16
- Si: 235/40R18
Choosing the correct stock size helps ensure accurate speedometer readings, proper handling, and balanced tire wear. If you replace tires with non-stock sizes, be mindful of overall diameter and clearance, and consider professional guidance to maintain performance and safety.
Additional considerations for wheel upgrades
If you plan to upgrade to different wheels, you may need to adjust tire width or aspect ratio to preserve the overall tire diameter. For example, moving to larger 17-inch wheels often requires a lower profile tire (such as 215/45R17 or 225/45R17, depending on the wheel width and model year). Always consult a tire and wheels expert to select sizes that fit your specific Civic and driving needs.
Summary
For a 2009 Honda Civic, stock tire sizes vary by trim: LX/DX use 195/65R15, EX/EX-L use 205/55R16, Hybrid uses 205/60R16, and Si uses 235/40R18. Always verify the exact size on the door jamb placard and consider how any aftermarket wheel changes might affect diameter and clearance.
