Factory tire sizes by wheel package
To determine the correct tire size, identify your trim and whether your car came with 16-, 17-, or (less commonly) 18-inch wheels. The tire size printed on the door placard is the authoritative source for your vehicle.
Common OEM configurations
These sizes reflect typical factory-installed configurations seen on the 2009 Accord sedan and coupe, noting that exact specs can vary by market and option packages.
- 16-inch wheel packages: 205/65R16
- 17-inch wheel packages: 235/45R17
- 18-inch wheel packages (less common, often on higher trims): roughly 235/40R18 or 235/45R18, depending on region
Always confirm the exact tire size for your vehicle on the door jamb placard or in the owner's manual, as regional differences and model variants exist.
Upgrading or changing sizes: what to know
If you’re considering tire replacement or wheel upgrades, several factors affect fit and safety beyond the stock size.
Guidelines for sizes beyond stock
- Keep the overall diameter within about 3% of the stock to avoid speedometer and ABS issues.
- Match or exceed the original load index and speed rating for safe performance.
- Check wheel width compatibility; wider tires may rub on suspension parts or fenders if not matched to the wheel.
- Significant diameter changes can affect traction control and alignment; recalibration or professional inspection may be needed.
- Non-OEM sizes can impact warranty coverage and insurance; consult a tire professional or Honda dealer if in doubt.
For precise fitment, especially when changing wheel diameter or going to a non-stock size, consult a tire specialist or your local Honda dealer with your VIN.
Summary
For a 2009 Honda Accord, the most common factory sizes are 205/65R16 on 16-inch wheels and 235/45R17 on 17-inch wheels. Verify your exact size on the door placard or in the owner’s manual, as trims and regional configurations varied. If upgrading tires or wheels, aim to preserve similar overall diameter, load index, and speed rating, and seek professional guidance to ensure proper fitment and safety.
