The correct tire size for a 2018 Honda CR-V depends on trim and wheel size: LX models use P235/65R17 tires, EX and EX-L use P235/60R18 tires, and Touring models use P235/55R19 tires.
In this article, we explain how to identify the exact size for your vehicle, why it varies by trim, and how to verify the right replacement tires. We also cover how to read tire codes, what counts as an acceptable alternative, and where to find reliable, up-to-date information.
Stock tire sizes by trim and wheel configuration
To help you shop with confidence, the following sizes reflect the typical OEM (original equipment) tires used on the U.S.-market 2018 CR-V, based on wheel diameter installed from the factory. Always confirm the size on your specific vehicle’s placard.
- LX – P235/65R17
- EX and EX-L – P235/60R18
- Touring – P235/55R19
These are the standard configurations Honda offered for the 2018 CR-V in common markets. If your vehicle has a different wheel package or is in a different region, confirm the exact size on the door placard or in the owner's manual.
How to verify your tire size on a 2018 CR-V
The most reliable way to confirm the correct size is to check the official labeling on your vehicle and the tire itself. Here’s how to verify step by step.
Door jamb placard
Look at the tire information placard attached to the driver’s door jamb. It lists the Original Equipment tire size for your trim, plus inflation pressures. This is the number you should match when replacing tires.
Tire sidewall and model code
On an installed tire, you’ll see a size code like P235/60R18. The numbers indicate tire width, aspect ratio, and wheel diameter. The letters denote the tire’s construction and other characteristics. Use this information to pair matching tires if you’re not using OEM sizes.
Owner’s manual as a reference
The owner’s manual includes a tire chart that corroborates the OEM sizes by trim and wheel option. If you’ve lost the placard or are unsure about your trim, the manual is a trusted secondary reference.
Interpreting tire codes and choosing replacements
Understanding the tire code helps you pick compatible replacements. Here’s what the common parts of a tire size mean and why they matter when replacing your CR-V tires.
- P: Passenger vehicle tire type
- 235: Tire width in millimeters
- 65/60/55: Aspect ratio (height to width)
- R: Radial construction
- 17/18/19: Wheel diameter in inches
- Load index and speed rating (e.g., 102T): Capability and maximum speed
When substituting sizes, aim to keep the overall diameter within about 3-5% of the original to maintain accurate speed readings, braking performance, and the functioning of stability control systems.
All-season, winter, and performance considerations
Most 2018 CR-V owners will use all-season tires for year-round performance. In regions with heavy snow, winter tires can improve traction, but you’ll want to ensure the size and tread pattern are appropriate for your wheels. Performance tires are generally unnecessary for daily driving in a CR-V and can affect ride comfort and efficiency if used in the wrong size or on the wrong trim.
Where to buy and what to ask for
When shopping, use the OEM size for the best fit and ride quality. If you’re considering alternatives, consult a tire professional about compatibility with your wheels and suspension, and whether the chosen size will affect ABS/traction control systems or speedometer accuracy. Always specify your trim and wheel size to ensure you’re comparing equivalent options.
Summary
For a 2018 Honda CR-V, the stock tire sizes vary by trim: LX uses P235/65R17, EX/EX-L use P235/60R18, and Touring uses P235/55R19. Verify your exact size on the door placard or in the owner’s manual, and when replacing tires, try to match the OEM diameter within a small tolerance to maintain vehicle performance and safety.
