To size a tractor tire, look at the tire sidewall for a series of numbers and letters. This sequence typically follows the format of width/aspect ratio x rim diameter. For example, a tire marked 320/85R24 indicates a width of 320mm, an aspect ratio of 85% (height is 85% of the width), and fits a 24-inch diameter wheel. Additionally, consult the tractor’s manual for specifications or contact a tire professional for advice on selecting the correct size for your tractor’s make and model, ensuring optimal performance and safety.
