On a Honda Accord, the exact tire size depends on the year and trim; the size is printed on the door jamb placard and on the tire sidewalls. For many recent Accords, sizes like 235/45R18 or 235/40R19 appear, but verification for your specific vehicle is essential.
The tire size information is not universal across all Accords; it can vary by market and wheel options. If you replaced wheels, the installed tires may differ from the original specification. The following guidance helps you identify the correct size for your vehicle, and the examples provide a reference point for what you might encounter when shopping or replacing tires.
How to find the exact tire size on your Accord
To identify the correct tire size for your vehicle, use these steps. This list guides you to the places that store the official size data and how to read it on your car.
- Check the driver's door jamb placard: It lists the official tire size for the front and rear tires (for example, P235/45R18). Note that some models have the same size on all four corners, while others show different sizes for front and rear wheels.
Once you locate the size, remember to confirm the load index and speed rating as well, and consider matching all four tires for balanced performance. If you’re unsure, consult a dealer or tire professional.
Common tire sizes you may encounter on recent Accords
In general, tire sizes vary by year and trim, but several sizes appear repeatedly on models from the last decade. The following examples give you a practical reference when shopping or comparing wheels.
- 235/45R18 — typical on EX, EX-L, and Touring models with 18-inch wheels.
- 235/40R19 — used on higher-end trims with 19-inch wheels.
- 205/65R16 — found on older or base-model Accords with 16-inch wheels.
Be aware that some market variants or special editions use different sizes; always verify with the placard or dealer documentation before purchasing tires or wheels.
Reading the tire code and what it means
Understanding the size code
The tire size printed on the sidewall follows a standard format, for example P235/45R18. In this code: P stands for passenger car, 235 mm is the width of the tire, 45 is the aspect ratio (the height as a percentage of width), R indicates radial construction, and 18 is the wheel diameter in inches. Other numbers may follow, indicating load index and speed rating, such as 94V. The door placard on the driver's door frame shows the recommended size for your vehicle, which is the one you should use for replacement unless a dealer advises otherwise.
If your Accord has aftermarket wheels, ensure the overall diameter remains close to the original to avoid speedometer error and clearance issues. Consult a professional if you’re unsure about compatibility or performance implications.
VIN-based verification and dealership resources
For a precise match, you can use Honda’s official VIN-based lookup tools or contact a dealer. The VIN can reveal the original wheel size, tire specifications, and whether a factory wheel option is installed on your vehicle. This is especially important if you bought the car used or changed rims, as it helps confirm the correct replacement sizes and avoids misfits.
Summary
The exact tire size for your Honda Accord is specific to your vehicle’s year, trim, and wheel option. The most reliable sources are the door jamb placard and the tire sidewalls, with the owner’s manual or dealer confirmation as backup. Sizes commonly seen on recent Accords include 235/45R18 and 235/40R19, but older base models may use 205/65R16 or other variants. Always verify before purchasing or mounting tires, and consider matching all four tires to maintain balanced handling and accurate speedometer readings.
