Sizes vary by trim and wheel setup: the 2017 Civic typically uses 205/55R16 on LX, 215/45R17 on EX/EX-T, and 235/35R19 on Touring. Always verify the exact OEM size on the door jamb sticker before purchasing. This article explains the common factory sizes and how to choose replacements safely.
Factory tire sizes by trim
Understanding the trim differences
The 2017 Civic lineup used different wheel diameters depending on trim, which drives the tire size. LX models commonly came with 16-inch wheels, EX/EX-T shifted to 17-inch wheels, and Touring adopted larger wheels as part of its higher-end setup.
- LX: 205/55R16
- EX and EX-T (17-inch wheels): 215/45R17
- Touring (usually 19-inch wheels): 235/35R19
OEM sizes provide the baseline for performance, ride quality, and safety. If your Civic has aftermarket wheels or a different wheel package, the tire size may vary from these figures.
Replacing tires: key considerations
Before choosing replacements, keep these guidelines in mind to preserve safety and vehicle behavior:
- Maintain overall tire diameter within about ±3% of the original size to preserve speedometer accuracy and ABS/traction control performance.
- Match the load index and speed rating appropriate for your vehicle’s specifications and driving conditions.
- Check that the chosen tire width and aspect ratio fit your wheel width and do not rub at full steering lock or suspension travel.
- Winter tires should be selected with sizes that fit your wheel setup and vehicle clearance; consider dedicated winter rims if you regularly switch seasons.
When in doubt, consult a tire professional or Honda dealer to confirm fitment, especially if you’re planning to mix sizes or install aftermarket wheels.
Where to buy and how to confirm
To ensure you get the correct tire size for your exact car configuration, rely on official sources and VIN-specific data.
- Check the driver’s door jamb sticker for the OEM tire size, load index, and speed rating.
- Consult the owner’s manual or Honda’s official service information for your trim’s specified tire package.
- When shopping, provide your model year, trim, and wheel size to the retailer or installer to verify fitment for your vehicle.
Always confirm fit with a professional before purchase if you’re considering non-standard sizes or aftermarket wheels.
