The size of a wheel cover is typically the wheel diameter in inches, with common sizes ranging from 14" to 20". To be sure, check your vehicle’s documentation, the tire size, or the current wheel cover for markings.
Identify the wheel size from official sources
To confirm the correct size without guessing, start with official sources that document the wheel or tire specifications.
- Owner's manual or manufacturer specifications for wheel size, typically listed as diameter in inches (for example, 16x6.5J).
- Vehicle placard or sticker in the door jamb, trunk lid, fuel filler door, or glove box that states wheel/tire size.
- Tire sidewall size; the number after the "R" indicates the wheel diameter (for example, in 205/55R16, the wheel diameter is 16 inches).
- Current wheel cover or hubcap markings; some wheel covers specify the size or compatible diameters on the inside surface.
- Dealership or manufacturer website lookup by year, make, and model if other sources are unavailable.
Using official sources ensures you match the exact diameter your vehicle was designed for, which is essential for both fit and safety.
Measure the wheel or cover directly
If documentation is missing or unclear, you can measure to determine the diameter yourself.
- Measure the wheel cover's outer diameter or the wheel's bead seat diameter by placing a tape measure across the widest point through the center.
- Be sure to measure the diameter that determines fit for hubcaps or full wheel covers, not the rim width.
- Record the measurement in inches; common wheel cover sizes are 14, 15, 16, 17, 18, and 20 inches.
- Compare the measurement with standard sizes to find the closest match or consult a catalog from the cover's manufacturer to confirm compatibility.
Accurate measurement minimizes the risk of buying a cover that is too small or too large for the wheel.
Common pitfalls and practical tips
Notes and considerations to avoid mistakes when identifying wheel cover size.
- Don't rely on tire width or aspect ratio alone; those numbers refer to the tire, not the wheel cover diameter.
- Be aware that some aftermarket covers are labeled by wheel diameter but designed for specific designs; verify the compatibility with your wheel style.
- If your vehicle uses a centered hub design, ensure the cover features the correct center hole size and mounting method (clips vs. retention rings).
- When in doubt, bring your current wheel cover or a photo to a retailer; many outlets can verify size based on the car model.
These tips help ensure you select a wheel cover that fits securely and aligns with your vehicle's aesthetic and safety requirements.
Summary
Wheel cover size is determined primarily by the wheel diameter in inches. Start with official documentation, then verify with the tire size, or measure directly if needed. With the right size, you’ll have a secure, proper-fitting wheel cover that complements your vehicle.
