The 2020 Honda Civic does not use a single tire size across all trims. The size depends on the trim level and the wheel package installed by the factory. The most common factory sizes are 205/55R16 for 16-inch wheels and 235/40R18 for 18-inch wheels.
In this article, we examine how tire sizes are determined on the 2020 Civic, outline the typical factory sizes tied to wheel size, and explain how to confirm the exact size for your specific vehicle.
Two main factory sizes by wheel size
Here are the two most common factory tire sizes you’ll find on a 2020 Civic, depending on wheel size. Note that some regional or dealer-specific configurations may deviate. Always verify with your car’s placard or owner’s manual.
- 16-inch wheels: 205/55R16
- 18-inch wheels: 235/40R18
In practice, the exact size is determined by the trim and wheel package. If your Civic uses a different wheel size than these two, check the door jamb placard or tire sidewall to confirm the correct specification.
Where to find the tire size information
The recommended tire size is listed on a placard inside the driver's door jamb. The same information appears on the tire sidewall and in the owner's manual under specifications. When buying replacements, match the original size and rating unless you have professional guidance for a different setup.
Important considerations for tire replacements
Altering tire size can affect speedometer accuracy, handling, and clearance. If you want to use larger or different-sized tires, consult a tire professional or Honda service to ensure proper fit and to avoid rubbing or clearance issues.
Summary
The tire size of a 2020 Honda Civic is not universal; base models with 16-inch wheels use 205/55R16, while higher trims with 18-inch wheels use 235/40R18. Always verify the exact size for your specific vehicle by checking the door placard or the tire sidewall, and seek professional advice if considering alternative sizes.
