There isn’t a single tire size that fits every Honda Accord. The correct size depends on the car’s year, trim, and wheel package; most recent Accords use wheels ranging from 16 to 19 inches, and the exact tire size is printed on the door jamb placard. If you’re unsure, the placard and the owner's manual are the most reliable sources.
In this article, we explain how to locate the exact size, what that number means, and what to consider if you need to replace or adjust tire sizes—whether you’re sticking with OE wheels or upgrading.
Where to find the right tire size
Door jamb placard
Open the driver's door and look for the placard on the door frame or latch area. It lists the recommended tire size (for example, a designation like "TIRE SIZE") and the recommended cold tire pressure for front and rear tires. This is the most reliable reference for your specific vehicle and wheel setup.
Owner's manual and vehicle information
The owner’s manual contains the official tire size for standard configurations and notes if different sizes are allowed with optional wheels. If you’ve replaced wheels or modified the model, the manual can confirm permitted alternatives and any impact on performance features.
Tire sidewall and manufacturer tools
Your current tires themselves show the size printed on the sidewall (for example, a designation such as P235/45R18). This can be a quick check if you’re replacing worn tires without access to the placard. For confirmation, you can also use Honda’s official online resources or a VIN-based tire size finder.
What to consider when replacing tires
Keep the overall diameter close to OE
When replacing tires, it’s best to match the overall diameter (the tire’s sidewall height and width relative to the wheel) to the original specification. A significant mismatch can affect the speedometer, odometer, ABS/traction control systems, and fuel economy. If you must deviate, limit the difference to about 2–3% in overall diameter.
Match load index and speed rating
Choose a tire with a load index and speed rating compatible with or higher than the original equipment. This helps ensure safety, handling, and warranty coverage, especially on higher-powered trims.
Winter tires and seasonality
If you drive in climates with snow or ice, consider dedicated winter tires. They are typically narrower and feature different tread patterns than all-season tires. If you switch to winter tires on the same rims, confirm you’ll have adequate clearance and no rubbing at full steering lock.
TPMS, alignment, and installation
After mounting any new tires, have the system reset or reprogrammed if required, and check wheel alignment and balance. Proper installation helps maximize tire life, handling, and safety.
Summary
The Honda Accord does not have a single universal tire size. To determine the correct size, check the door jamb placard and the owner's manual, and verify with current tires' sidewall markings or a VIN-based resource. When replacing, aim to match the original overall diameter and load/speed ratings, and consider seasonal tires where appropriate. If upgrading wheels, confirm clearance and factory systems compatibility to maintain performance and safety.
