🪁 235 60 R18 Vs 235 65 R17

^{235/60-R17 tires are 2.11 inches (53.6 mm) larger in diameter than 145/70-R18 tires and the speedometer difference is 7.5%.} Tire Size and Comparison Calculator calculate tire diameter from code and compare speedometer differences for tire sizes. The first number 225 is the tire width in millimeters. The 2nd number 60 is used to calculate the sidewall height or "aspect ratio", by percentage. So, the sidewall height of a 225/60 R 17 tire is 60% of 225 = 192. 235/55 R17. 235/60 R17. 235/65 R17. 235/80 R17. 245/40 R17. 245/45 R17. 245/50 R17. 245/55 R17. 245/65 R17.

The calculation results are presented in the form of visual infographics, on which tire with size 225/60 R18 is on top, and tire with size 235/55 R19 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 first number 245 is the tire width in millimeters. The 2nd number 60 is used to calculate the sidewall height or "aspect ratio", by percentage. So, the sidewall height of a 245/60 R 18 tire is 60% of 245 = 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 . 219 60 266 117 772 140 284 782
