Both in the table and in the graph, the tires are compared according to the following indicators: overall diameter, section width, circumference, sidewall height and clearance. Also, the online application calculates the difference in real speed and speedometer readings if the difference between tire 245/45 R18 and tire 235/50 R18 is significant.
For instance, in a tire with the size P215/45R17, the aspect ratio is 45. The aspect ratio represents the height of the tire’s sidewall as a percentage of its width. In the case of a 45 tire aspect ratio, the sidewall height is 45% of the tire’s width. Similarly, for a 50 tire aspect ratio, the sidewall height is 50% of the tire’s width.275/40-R18 tires are 0.37 inches (9.5 mm) smaller in diameter than 255/45-R18 tires and the speedometer difference is 1.4%.
