The car is an Audi A3 Sportback Bothin 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 235/45 R18 and tire 235/35 R19 is significant. Sizedifference between 225/40 R18 and 235/45 R18 tires. In the tire comparison table above, you can see a detailed calculation of the size difference between 225/40 R18 and 235/45 R18 tire. The calculation Thecalculation results are presented in the form of visual infographics, on which tire with size 235/50 R18 is on top, and tire with size 255/45 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 245/45 R19. 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 55 is used to calculate the sidewall height or "aspect ratio", by percentage. So, the sidewall height of a 225/55 R 18 23560-R18 tires are 0.93 inches (23.5 mm) smaller in diameter than 235/65-R18 tires and the speedometer difference is 3.1%. yXRe.

In this case, a 225 tire would have a height of around 631.4 millimeters. On the other hand, a 235 tire would measure about 641.4 millimeters in height. As a result, the 235 tires are roughly 0.39 inches or 10 millimeters taller than the 225 tires. SpeedoDifference between Wheels 12.1% Comparison Table. Model. 235/45 R18. 235/50 R18.
