How to Choose the Right Tire Size for Your Vehicle

🚘 Why Tire Size Matters

Choosing the right tire size is essential for safety, performance, and fuel efficiency. The wrong size can lead to poor traction, uneven wear, or even mechanical issues.

🔍 How to Read a Tire Size Code (e.g. 225/65R17)

  • 225 → Tire width in millimeters
  • 65 → Aspect ratio (sidewall height as a % of width)
  • R → Radial construction
  • 17 → Wheel diameter in inches

Example: A 225/65R17 tire is 225mm wide, 146.25mm tall (65% of 225), and fits on a 17-inch rim.

🚗 3 Ways to Find Your Vehicle’s Tire Size

1. Check Your Current Tires

Look directly at the sidewall of your existing tires for a code like P215/60R16.

2. Driver’s Side Door Sticker

Open the driver’s door and look for the manufacturer’s sticker. It usually includes the recommended tire size and pressure settings.

3. Vehicle Owner’s Manual

Your manual provides exact tire size and seasonal alternatives (e.g. narrower winter tires).

❄️ Do Winter Tires Have Different Sizes?

Yes – sometimes winter tires are slightly narrower for better grip in snow. Check manufacturer guidelines before downsizing.

Example: If your factory tire is 235/60R18, your winter tire might be 225/65R17.
