TireSize and Comparison Calculator calculate tire diameter from code and compare speedometer differences for tire sizes. The first number 235 is the tire width in millimeters. The 2nd number 55 is used to calculate the sidewall height or "aspect ratio", by percentage. So, the sidewall height of a 235/55 R 19 tire is 60% of 235 = 192.Thecalculation results are presented in the form of visual infographics, on which tire with size 225/55 R18 is on top, and tire with size 225/50 R18 below. Both in the table and in the graph, the tires are compared
