Thecalculation results are presented in the form of visual infographics, on which tire with size 225/60 R18 is on top, and tire with size 235/60 R18 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.
Compare225/55 R18 vs 225/55 R17. So, the sidewall height of a 225/55 R 18 tire is 60% of 225 = 192. The 3rd number 18 (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. The rim edge, or lip, extends past the tire bead seat to hold the bead and
