There isn’t a single tire size for every 2018 Accord—the correct size depends on your trim and wheel diameter.
The 2018 Honda Accord offered 17-, 18-, and 19-inch wheels across several trims, and the OEM tire size varies accordingly. To confirm the exact size for your car, check the tire placard on the driver’s door jamb or consult the owner’s manual or Honda’s official specifications. This article provides typical sizes by wheel diameter and guidance for choosing tires.

Trim-specific notes
To help you identify the correct tire size, this section lists typical OE configurations by wheel diameter. Your exact size may differ by trim and package, so verify with the vehicle’s placard.
- 17-inch wheels — typically P235/45R17
- 18-inch wheels — typically P235/45R18
- 19-inch wheels — typically P235/40R19
Note: Some trims or seasonal packages might use slightly different ratios; the door placard remains the definitive source.
Choosing tires beyond the OE size
Beyond matching the factory size, consider the tire type that fits your climate and driving style. The following categories are most common for the Accord in 2018 models.
- All-season tires for year-round use with balanced performance and longevity
- Winter tires for improved traction in snow and ice (recommended in cold climates)
- Summer or performance tires for enhanced grip in warm weather and sport handling
- All-terrain tires are generally not necessary for typical road use unless you encounter light off-road or snow conditions
When selecting tires, ensure the load index and speed rating meet or exceed the vehicle’s requirements. Consider climate, driving style, and warranty when making a choice; a tire professional can help tailor the selection to your needs.
Finding the exact specification for your vehicle
The most reliable source is the tire placard on the driver's door jamb, which lists the recommended size, inflation pressure, and load rating for your specific car. The owner's manual also contains a tire size chart, and you can consult Honda’s official specifications for your trim if you need confirmation.
Summary
In short, a 2018 Honda Accord does not have a single universal tire size. The correct tire size depends on trim and wheel diameter, with common OE sizes including 17-inch P235/45R17, 18-inch P235/45R18, and 19-inch P235/40R19. Always verify your exact size on the door placard or manual, and choose tires that match the spec and your driving conditions.
