What size tire for 2018 Honda Accord?

The correct tire size depends on your trims and wheel package. In general, Accord models from that year used 16- to 19-inch wheels with corresponding tire sizes, and the exact specification should be taken from the door jamb placard or the owner's manual for your specific vehicle.

More detail: The 2018 Honda Accord was offered in multiple trims with varying wheel-and-tire configurations. Base LX typically rode on smaller 16-inch wheels, while higher trims could wear 17-, 18-, or 19-inch wheels. Common OE tire sizes you might encounter across these configurations include 215/60R16, 235/45R17, 235/45R18, and 235/40R19, but exact sizes can vary by market and package. Always verify the precise size printed on the door placard or the tire sidewall.

Common wheel diameters used on the 2018 Accord

Before listing sizes, note that the wheel diameter determines the tire size that came from the factory. The following sizes are representative of typical OE setups for many 2018 Accords, but passengers should confirm their own vehicle's specification.

• 16-inch wheels: 215/60R16 (common on LX and some base configurations)


• 17-inch wheels: 235/45R17


• 18-inch wheels: 235/45R18


• 19-inch wheels: 235/40R19

These sizes serve as a practical reference for deciding on replacements, but the exact tire size can differ by trim and regional market. Always double-check the exact specification for your car.

How to confirm your exact tire size

To be certain you use the correct tire size when replacing tires, follow these steps:

1. Look at the driver’s door jamb placard for the Tire Size information printed on a sticker.


2. Inspect the sidewall of one of your current tires for the alphanumeric tire size (e.g., 235/45R18).


3. Consult the owner’s manual or the Honda dealership for the exact OE specification for your VIN and trim.


4. When in doubt, provide your VIN to a tire professional to confirm the appropriate size and any recommended alternatives.

Verifying the precise size ensures you replace like-for-like and maintain the intended handling and ride quality.

Tire replacement considerations

Beyond size, consider load rating, speed rating, tire type, and regional climate. For example, many 2018 Accords use all-season tires with a certain load/speed rating appropriate for the wheel diameter, and opting for a different size may require recalibration of the speedometer or adjustments to suspension components. If you’re moving to a non-stock size, consult a tire professional to ensure safety and performance are preserved.

• Keep the same size all around or ensure a matched pair when replacing only two tires.


• Match the load index and speed rating to the vehicle’s specifications or those recommended by Honda for your trim.


• Be aware that changing wheel diameter without proper adjustment can affect odometer accuracy and traction control.

Replacing tires with the correct specifications helps preserve handling, safety, and warranty coverage.

Summary

The 2018 Honda Accord used multiple OE tire sizes depending on trim and wheel package, typically ranging from 16-inch wheels with around 215/60R16 to 19-inch wheels with around 235/40R19. To ensure accuracy, always check the door jamb placard or tire sidewall for your exact size and consult a tire professional if you plan any size changes.
