When it comes to measuring, Europe and America diverge greatly. Generally speaking, Europeans measure with the metric system, while Americans use measurements such as feet and inches. So, it’s no surprise that some differences exist between European tire sizes and American tire sizes, though those differences may not be as extreme as you might think.
Tractor Tire Sizes
Though tractor tires do not use the same measuring system as the measuring system used on vehicles, which, in the case of American cars, is the P-metric measuring system, the measurements for tractor tires are somewhat similar. Like passenger car tires, tractor tire measurements generally show either two or three aspects of tire size.
Tire Size Components
If only two numbers appear in the measurement of a tire, these numbers represent the width and the diameter, in that order. If three numbers appear in a tire measurement, these numbers represent the height, width and diameter, in that order. The width of the tire is the distance across the tire face, the diameter is the size of the tire rim, and the height is the height of the tire when properly inflated.
When it comes to measuring tires, American tractor tire companies use the same measurements used in other areas. The height, width and diameter of a tractor tire is listed in inches. If you want a better representation of the size of a tire, you can convert the number to a different measurement. A tractor tire with a height measurement of “36,” for instance, stands 3 feet tall when fully inflated.
The main difference between American tire sizes and European tire sizes is that Europeans do not use inches. As in all other areas, Europeans use the metric system when measuring tires. Tractor tires are measured in millimeters. These tire sizes can be easily converted into meters, which is a similar measurement to the American yard.
Buying Tractor Tires
When you are buying tractor tires in the United States or Europe, you won't generally need to worry about differences in American and European tractor tire sizes. Most manufacturers that import tires from other countries make those conversions for you.
