Different Indian wheel manufacturers for tractor provide different sizes of tractor wheels, we must understand that which tire is perfect for our tractor, what is the size of wheel our tractor requires and hot to measure it.
Tire Sizes Explained
Understanding the tire and tire size is the first step in selecting the proper tractor wheels and tire rim. Depending on the manufacturer and tire use, almost all tire sizes are usually stated in either standard size or metric.
What does a tire size with two digits mean?
The size numbers on your tire signify if it contains two sets of numbers (10-16.5, 12.4-16, or 18.4R28). The first number in our first example of tire size 10-16.5 is the tire’s width in inches. The second number in the example 16.5 is the actual diameter measurement of the wheel that the tire is designed to fit. In other terms, a 10-16.5 tire is 10″ wide and includes a rim that is 16.5″ in diameter.
What does a tire size with three digits mean?
The size numbers on your tire indicate if it has three sets of numerals (18×8.50-8). The initial number 18 in our tire size 18×8.50-8 example is the tire’s entire diameter (outer height) in inches. The second number is the actual width of the tire, and the third number is the rim size in inches.
Measuring the Width and Diameter of Your Tractor Rims/Wheels
The width of a tractor wheel rim should be measured from the inside of the bead lip to the inside of the opposing bead lip. Many tractor and equipment owners inaccurately measure the total width of the rim, resulting in the purchase of a replacement rim that does not fit the tire. The same method is used to measure the rim diameter. Remember that the rim diameter is measured to the first flange (drop) of the bead lip on the rim itself, not the total height.
The Tractor Wheel Bolt Pattern: Understanding and Measuring
A tractor wheel or rim’s bolt pattern consists of lug holes in the rim where the lug bolts/studs and nuts hold the wheel to the tractor or equipment. The lug holes are the spots on the wheel where the lug nut or lug bolt is inserted to attach the wheel to the equipment. There are usually at least three bolt holes in a circle around the central hub hole in the centre of the wheel, and often more. The term “bolt pattern” refers to the layout and distance pattern in which the lug nuts are fastened to the wheel or rim.
To determine the bolt pattern, we must first count the number of bolt holes in (or that must be in) the rim and ensure that it corresponds to the axle hub. After determining the number of bolt holes, you will measure the distance between the holes themselves.
Wheel Offset: Understanding and Measuring
While the bolt holes and centre hole of any wheel are located precisely in the centre of the wheel (if they were not, a revolution would “hop” as it went around), many people also believe that the mounting point of the wheel to the hub (where the bolt holes are) is located the same distance (with the spine vertical and mounted to the machine) from the inside of the wheel to the outside of the wheel. While this is true in certain circumstances, the wheel bolts and mounting centre are often “Offset” to be closer to the inner or outside border of the wheel ring when installed to the machine. When the wheel is connected to the hub, the offset causes it to be closer or farther away from the axle.
