The 2009 Honda Civic uses three common OEM tire sizes depending on wheel diameter: 195/65R15 on 15-inch wheels, 205/55R16 on 16-inch wheels, and 235/40R18 on the Civic Si’s 18-inch wheels. Always verify the exact size on the door placard or in the owner’s manual.
In this article, we break down the tire sizes by wheel size and trim, explain how to choose tires based on climate and driving style, and offer practical maintenance tips to keep a 2009 Civic safe and efficient on the road.
OEM tire sizes by wheel size
The following sizes reflect the most common factory setups for a 2009 Civic, depending on wheel diameter. Always confirm the exact spec on the vehicle's door sticker or owner's manual, as trims and markets can differ.
- 15-inch wheels: P195/65R15 (typical on DX/LX and base configurations)
- 16-inch wheels: P205/55R16 (typical on EX, EX-L and hybrids with 16-inch rims)
- 18-inch wheels: P235/40R18 (specific to the Civic Si with 18-inch performance wheels)
Note: Some markets or model years offered alternative OEM sizes or optional wheel packages. Always verify the exact size on the placard on the door jamb and the owner’s manual.
Choosing tires by climate and driving style
Beyond the exact size, the tire type matters for performance, comfort, and safety. Here are the common choices when selecting tires for a 2009 Civic.
- All-season tires: Balanced options suitable for most climates, providing a mix of dry and wet grip, comfort, and tread life. They are the default choice for daily driving.
- Winter (snow) tires: Essential in snowy or consistently cold climates; use dedicated winter tires with appropriate tread compounds for safer traction on ice and snow.
- Summer or high-performance tires: For drivers prioritizing grip and handling, typically used on the Civic Si or in warm-weather regions; tread compounds favor dry and wet performance but wear faster in cold temperatures.
- Touring or fuel-efficient tires: Focus on low rolling resistance and comfort for maximizing MPG and a smooth ride; compatible with OEM sizes and trims.
When selecting tires, ensure the load index and speed rating meet or exceed OEM specifications. Also consider a proper tire rotation schedule and inflation pressures per the placard for even wear and safe handling.
Maintenance and replacement tips
Regular upkeep helps you get the most life out of your tires and maintain performance on a 2009 Civic.
- Check tread depth regularly and replace when it reaches 2/32 inch (1.6 mm) or as recommended by the tire manufacturer.
- Maintain correct inflation pressure as listed on the door placard, not the tire sidewall, and adjust for load and seasonal temperature changes.
- Rotate tires (typically every 5,000–7,500 miles) to promote even wear across axles.
- Inspect for uneven wear or alignment issues and have the alignment checked if you notice pulling or steering wheel vibration.
In all cases, use tires that match the wheel size and align with your vehicle's safety systems, including ABS and stability control, to maintain proper performance.
Summary
The 2009 Honda Civic uses three main OEM tire sizes based on wheel diameter: 195/65R15 on 15-inch wheels, 205/55R16 on 16-inch wheels, and 235/40R18 for the Civic Si’s 18-inch setup. Always confirm with the door placard or manual before purchasing, and choose tires that suit your climate, driving style, and performance needs. Regular maintenance and correct inflation help maximize safety, efficiency, and tread life.
