How to Use a Tire Size Calculator
A Tire Size Calculator will let you know the tire dimensions based on the wheel's diameter and the code of the tire. The calculation is not affected by the type of tire construction. After confirming the code, the calculator will display the details of the tire, including the circumference, sidewall height, and number of revolutions per mile. Alternatively, you can enter your desired measurements in the appropriate units to find out the exact dimensions of your tire. When calculating the size of a tire, the aspect ratio (AH) is entered. This is the ratio of the height of the section to its width. The height is measured from the rim's edge to the outer edge of the tire. The width is measured from the sidewall to the rim. The ah/65 code means that the tire's height is 65% of the corresponding width. The width, on the other hand, is equal to the rim's height. tiresizehelp.com When using a Tire Size Calculator, you must know the type of tire you need for your vehicle
