Inaccurate input leads to the selection of chains that may be either too large or too small, compromising safety and performance.
-
Reading Tire Sidewall Markings
Tire size is encoded on the sidewall using a standardized alphanumeric code. For example, “215/65R16” indicates a tire with a 215 mm section width, a 65% aspect ratio (sidewall height as a percentage of section width), and a 16-inch rim diameter. Failure to accurately transcribe this code into the calculator will result in an incorrect size recommendation. Many tools provide diagrams to assist users in locating and understanding this information.
-
Understanding Aspect Ratio
The aspect ratio, represented as a percentage, dictates the tire’s sidewall height relative to its width. This value is critical because it influences the overall diameter of the tire. Even with the same rim diameter, tires with differing aspect ratios require different chain sizes. A higher aspect ratio means a taller sidewall, and thus a larger chain may be needed.
-
Considering Tire Type Variations
Different tire types, such as all-season, winter, or performance tires, may have slight dimensional variations even with the same nominal size. These variations can influence the fit of traction devices. Certain tools allow for the input of specific tire models to account for these subtle differences and provide a more tailored chain size recommendation.
