A 215/50R17 tire stands approximately 25.5 inches tall. This measurement is derived from the tire's sidewall height, which is 50% of its width (215mm), added to the diameter of the wheel (17 inches). To calculate: the sidewall height in inches (215mm * 0.50 / 25.4) is about 4.25 inches. Since there are two sidewalls (top and bottom), you double this number and add the wheel diameter: (4.25*2) + 17 = 25.5 inches.
