The calculation results are presented in the form of visual infographics, on which tire with size 225/65 R17 is on top, and tire with size 235/60 R17 below. 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.

The 2nd number 65 is used to calculate the sidewall height or "aspect ratio", by percentage. So, the sidewall height of a 225/65 R 17 tire is 60% of 225 = 192. The 3rd number 17 (generally preceded by an "R") is Rim Diameter in inches. This is the diameter of the rims bead seat base, not the diameter of the outer rim edge. .
