Understanding Tire Sizes

Before delving into the specifics of 33-inch and 285 tires, it is important to understand how tire sizes are measured. Tire sizing nomenclature can be confusing, but it follows a standard format that includes three numbers separated by slashes. For example, a tire size of P225/60R16 means that the tire is a passenger car tire, 225 millimeters wide, with a height-to-width ratio of 60%, and fits on a 16-inch wheel.
