The tire size calculator decodes tire measurements and calculates actual dimensions. Understanding tire size is important for replacements, upgrades, and ensuring proper fitment.
Enter width (in mm), aspect ratio (sidewall height as % of width), and rim diameter (in inches). The calculator shows sidewall height, overall diameter, and other specifications.
This helps when shopping for tires, comparing different sizes, understanding how size changes affect speedometer accuracy, and ensuring replacement tires match your vehicle's requirements.
