# Tire Size Calculator

A tire size calculator is a tool used to determine the appropriate size of tires for a vehicle. It is typically used when replacing tires, or when upgrading to a different size of tire. The calculator typically requires input of the vehicle’s make, model, and current tire size, and can provide options for alternative tire sizes that will fit the vehicle.

Some tire size calculators will also take into account the intended use of the vehicle, such as whether it will be primarily used for highway driving or off-roading, in order to provide more specific recommendations.

A tire labeled as 33×12.50R15 would be 33 inches in diameter and 12.50 inches in width, while a tire labeled as 285/70R17 would be 285 millimeters wide and 70% of the width is the sidewall height.
