There isn’t a single tire size for all Honda Accords—the correct size depends on the model year and trim. To be sure, check the doorjamb placard, the owner's manual, or the official Honda specifications for your car. If you share your year and trim, I can give the exact OEM size.
Finding the exact tire size for your Accord
To identify the right tire size for your vehicle, start with the sources that Honda uses to specify factory equipment and recommendations.
Door jamb placard
The most reliable on-car source is the tire and wheel placard on the driver’s side door jamb. It lists the recommended tire size (for example, P235/45R18) and the required cold tire pressures.
- Look on the sticker near the door latch on the driver’s door for the size printed as something like P235/45R18, along with the recommended pressure.
- Note that some trims may show different sizes if they use different wheels or run-flat tires; always match to the exact door placard for your car.
- If you can't access the car, the placard information is often also printed on a sticker in the fuel filler door or in the owner's manual.
Conclusion: The door jamb placard is the quickest, most reliable way to confirm the correct tire size for your Accord.
Owner's manual and official specs
If the door placard is missing or you’re researching before a purchase, consult the owner's manual or official Honda specifications for your year and trim. The manual describes wheel sizes and tire types recommended by the manufacturer.
- Check the manual’s sections on tires and wheels for the recommended sizes and load/speed ratings.
- Some years have multiple recommended sizes depending on wheel options; verify against your vehicle’s trim and wheel code.
Conclusion: The manual is a solid secondary source, especially when the door placard isn’t accessible.
Current tires on the car
You can also read the size directly from the sidewall of any tire currently installed on the car. If you’re shopping for replacements, this is a quick check to ensure compatibility.
- Find the alphanumeric size code on the sidewall, e.g., 235/45R18, which matches the vehicle’s OEM specification in most cases.
- Note the load index and speed symbol (e.g., 94V) as these influence performance and safety.
Conclusion: Reading the current tires helps you select a compatible replacement size, provided you’re keeping within the manufacturer’s guidelines.
Understanding tire size codes
Understanding the size code on a tire helps you identify what each number and letter means, and whether a replacement size will be compatible with your Accord.
Here’s how to decode a typical tire size found on a Honda Accord:
- Width in millimeters (the first number, e.g., 205, 235).
- Aspect ratio (the two-digit number following the slash, e.g., 60, 45).
- Construction type (R for radial).
- Wheel diameter in inches (the number after the R, e.g., 16, 18, 19).
- Load index and speed symbol (the trailing numbers/letters, e.g., 94V).
Conclusion: The size code conveys the essential dimensions and performance ratings, and is what you’ll match when replacing tires.
OEM sizes vs. approved alternatives
When replacing tires, you generally want to use the OEM size or a size within manufacturer guidance. Altering the diameter by more than a small amount can affect speedometer readings, braking, and clearance, so proceed with caution.
- Maintain the overall diameter within about 3% of the OEM to avoid affecting accuracy of the speedometer and anti-lock braking systems.
- Consider the effect on ride quality, handling, and warranty if you use non-OEM sizes.
- Consult a tire professional or dealer for recommendations if you’re thinking about alternate sizes for a particular wheel setup.
Conclusion: For safety and performance, stick to the OEM size or a nearby approved alternative, and verify compatibility with wheel width and clearance.
Summary
The Honda Accord doesn’t have one universal tire size. The exact size depends on the model year, trim, and wheel option. To determine the correct tire size, check the driver’s door jamb placard, consult the owner's manual, and verify the tire sidewall you’re replacing. If you tell me the year and trim, I can provide the precise OEM size for you and help you compare replacements.
