Calculate
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
In the table above you can see a detailed comparison of the difference in dimensions, parameters and performance between a 275/65 R18 tire and a 275/75 R18 tire. The calculation results are also presented in the form of visual models (infographics), on which the tire with the size 275/65 R18 is on top, and with the size 275/75 R18, respectively, at the bottom. The visualization was generated in two projections: lateral (left) and frontal (right). The online calculator compares tires according to the following characteristics: diameter, width, circumference, profile height, revolutions per km, ground clearance change. Additionally, a potential deviation between the actual speed and the speed displayed on the speedometer is calculated, which can occur if the difference between tires 275/65 R18 and 275/75 R18 is significant. US and UK inch version of calculations.
If you want to compare other tyres, just select the required parameters in the drop-down fields and click on the green button.
