Tractor tires come in a variety of sizes, and it's important to choose the right size for your tractor. The size of a tractor tire is usually indicated in either standard or metric sizes, and understanding the two different measurements is key to finding the right tire for your tractor. The standard tire size is the easiest of the two measurements to read. An example of a standard tire size is “16, 9 — 30”.
Here, “16, 9” indicates the tire width in inches and “30” indicates that the tire will fit a 30 inch diameter wheel. An example
of tractor tiresizes expressed in the standard format would be “14.9-42”. The “14.9” means that the tire is 14.9 inches wide and the “42” indicates that this tire fits a 42 inch diameter wheel. The hyphen “: indicates that the construction of the tire has a skewed layer, but could be an “R” if the tire is radial. The

The first number before the “x” indicates the diameter of the tire when it is inflated and not under load. The middle number between the “x” and the “-” indicates the width of the tire. The final number indicates the width of the tire. Please note that this last number is always the width, not the diameter of the tire. To measure the circumference of a tractor tire, you must secure one end of a rope at the starting point and wrap it around the tire.
Mark where it crosses back over itself and measure this length. Divide this measurement by 3.14 to get the diameter of your tire. When you're thinking about how to measure the tires and rims of a tractor, it's also important to check the inside of the heel fringe, as many manufacturers indicate the tire size there.

Once you have all these measurements, you are ready to confidently buy the right wheels and tires for your tractor, equipment or trailer.
