The factory tire setup for the 2018 Honda Accord Sport is 235/40R19 on 19-inch wheels. Brand and specific tire model can vary by production batch and region, so the exact choice may differ from car to car; always verify using the placard on the driver’s door jamb for your vehicle.
Tire size and what it means for the Accord Sport
Understanding the size helps with rotation, replacements, and performance expectations. 235/40R19 indicates a 235 mm wide tread, a 40% aspect ratio (sidewall height), and 19-inch wheel diameter. The 19-inch setup is paired with a relatively low-profile sidewall for sharper handling and a more aggressive stance, but it can yield a firmer ride and a different road feel. The Sport trims of the 2018 Accord used 19-inch wheels, while other trims used smaller wheels.
Where to confirm the exact OEM brand/model
To determine the exact brand and model that was installed by the factory, check the door jamb placard on the driver's side and the owner's manual. The placard lists the recommended tire size and may also indicate the original tire brand. If you're replacing tires, aim to match the size (235/40R19) and maintain comparable load and speed ratings; the brand/model can vary by production date and market.
Practical tips for tire shopping
When replacing, you’ll want to maintain the same size and an equivalent or better performance rating. Ensure proper inflation, consider all-season vs. UHP tires depending on climate and driving style, and remember to perform regular rotations to even out wear. If you replace just one tire, match the brand and model as closely as possible across the remaining tires to preserve handling characteristics.
Summary
The 2018 Honda Accord Sport uses 235/40R19 tires on 19-inch wheels as the OEM setup. The exact tire brand and model can vary by production batch and region, so the best reference is the door jamb placard in your car. For replacements, stick to the same size and aim for a similar performance class to preserve handling and safety characteristics.
