      How to Read Your Tire Size to Find the Right Tire Chains

      Understanding your tire size is crucial for selecting the correct tire chains, ensuring a snug fit and optimal performance in snowy or icy conditions. The tire size is displayed on the sidewall of your tire as a combination of numbers and letters. Here’s how to decode it to choose the perfect snow chains or tire chains: 

      Example: 205/55R16 91H

      This diagram breaks down each element of the tire size, helping you understand what the numbers and letters represent. Let’s go through them step by step:

      1. Tire Type

      • Indicates the type of tire, such as:
        • P: Passenger vehicle tire.
        • LT: Light truck tire.
        • T: Temporary tire (spares).
      • When purchasing tire chains, ensure compatibility with your tire type.

      2. Section Width (205)

      • The width of the tire from sidewall to sidewall, measured in millimeters.
      • This tire is 205 mm wide. Snow chains must match this width for a secure fit.

      3. Aspect Ratio (55)

      • The height of the tire’s sidewall as a percentage of its width.
      • A ratio of 55 means the height is 55% of the width. This helps determine chain clearance.

      4. Tire Construction (R)

      • Indicates the tire’s internal structure.
        • R: Radial construction.
        • B: Bias-ply.
      • Most tire chains are designed for radial tires.

      5. Wheel Diameter (16)

      • The diameter of the wheel that the tire fits, measured in inches.
      • This tire fits a 16-inch wheel, and chains must match this size.

      6. Load Index (91)

      • A numerical value representing the maximum weight capacity of the tire.

      7. Speed Rating (H)

      • The maximum speed the tire can handle safely.
        • H corresponds to 130 mph (210 km/h).
      • Some tire chains come with speed restrictions.

      Why Tire Size Matters for Tire Chains

      Selecting snow chains based on your tire size ensures a precise fit, critical for safe driving in winter conditions. A proper fit prevents slippage and reduces the risk of damage to your tires or vehicle.
