The hubcap size on a 2019 Honda Civic varies by trim; there isn’t a single universal size. The LX uses 16-inch wheel covers on steel wheels, while higher trims use alloy wheels and typically do not require separate hubcaps. Wheel sizes range from 16 to 19 inches depending on the trim.
In practice, the 2019 Civic lineup in the United States featured 16-inch wheel covers for the LX, 17-inch alloy wheels for EX/EX-L, and 18-inch alloy wheels for Sport and Touring, with the performance Si model using 19-inch alloy wheels. To confirm the exact size for a specific car, check the door placard or the vehicle’s VIN/build sheet.
Wheel and hubcap details by trim
Below is a quick guide showing which Civics use wheel covers (hubcaps) and the typical wheel diameters by trim.
- LX — 16-inch steel wheels with full wheel covers (hubcaps).
- EX and EX-L — 17-inch alloy wheels (no separate hubcaps).
- Sport and Touring — 18-inch alloy wheels (no separate hubcaps).
- Civic Si — 19-inch alloy wheels (no separate hubcaps).
In short, hubcaps are used only on the LX with steel wheels; otherwise, wheel sizes are determined by trim and typically do not use separate hubcaps.
How to verify your car’s wheel size
To confirm the exact wheel diameter for your vehicle, check the placard on the driver's door jamb, which lists the wheel size, or inspect the tire sidewall, which shows the wheel diameter as the last number in the tire size (for example, a tire size like P205/55R16 indicates a 16-inch wheel). If your Civic has aftermarket wheels, the hubcaps may be different or not used at all. The VIN or Honda’s owner portal can also reveal the original wheel size installed at the factory.
Summary
For the 2019 Honda Civic, there isn’t a single hubcap size. The LX uses 16-inch wheel covers on steel wheels, while EX/EX-L use 17-inch alloy wheels, Sport and Touring use 18-inch alloy wheels, and the Civic Si uses 19-inch alloy wheels. Verify your exact size with the door placard or VIN for accuracy, especially if you’re dealing with aftermarket wheels.
