Belarus Tractor Rear Tire Size: All You Need To Know

Tractor tyre sizes can be written in many different formats, but the first number always represents the width of the tyre from sidewall to sidewall, and the second number represents the rim diameter. For example, the numbers 11.2 x 20 indicate a tyre width of 11.2 inches and a rim diameter of 20 inches. Belarus tractors, such as the Belarus 520, can fit rear tyres with measurements of 11.20-20.

The rear tire size for a Belarus 520 tractor is 11.20-20

In the metric format, the tractor tire size would be expressed as 284/70R20. The first number, 284, indicates that the tire is 284 mm wide. The second number, 70, represents the aspect ratio or the sidewall height as a percentage of the tire's width. So, the sidewall height for this tire is 70% of 284 mm, which is about 198.8 mm or 7.82 inches. The letter "R" indicates that the tire is radial, and the third number, 20, indicates the rim size in inches.

It is important to maintain the correct tire size for your tractor, especially if it is a 4x4 or 4WD model like the Belarus 520. Changing the tire size ratio can damage the gear train. While the overall tire height can be adjusted, it is crucial to change both the front and rear tire profiles equally to avoid issues.

The standard format for tractor tire sizes is XX.X-XX

Tractor tyre sizes can be written in many different formats, but the standard format is usually simpler than the metric format.

The standard format for tractor tyre sizes is XX.X-XX. The first number (XX.X) represents the width of the tyre in inches. The second number (XX) represents the diameter of the rim in inches. For example, the size 14.9-42 means the tyre is 14.9 inches wide and fits a 42-inch diameter wheel. The dash (-) indicates that the tyre construction is bias-ply, but this could be an 'R' if the tyre is radial.

It's important to note that the front and rear tyres on a tractor are usually different sizes, with the front tyres being shorter than the rear ones. This size ratio needs to be maintained to ensure the tractor sits level. For 4x4 tractors, changing this ratio can damage the gear train. While the overall tyre height can be changed, it's crucial to adjust the front and back tyre profiles equally to avoid issues.

Belarus tractors, such as the Belarus 520 model, typically use the standard format for tyre sizes. For example, the front and rear tyre size for the Belarus 520 is 11.20-20. This means the tyre is 11.20 inches wide and fits a 20-inch diameter wheel.

The first number in the standard format is the tire width in inches

Tractor tyre sizes can be written in many different formats, and there are two main ways that manufacturers express tractor tyre sizes. One method uses the "standard" format, and the other uses the "metric" format.

The standard method of size expression is relatively simple, but not as descriptive as the metric format. An example of a tractor tyre size expressed in the standard format would be "14.9-42". The "14.9" means the tyre is 14.9 inches wide and the "42" tells us that this tyre fits a 42-inch diameter wheel. The dash "-" indicates the tyre construction is bias-ply, but this could be an "R" if the tyre is radial.

The first number in the standard format is the tyre width in inches. So, in the example "14.9-42", the first number "14.9" means the tyre is 14.9 inches wide. This is an important specification to note as it will impact the performance and suitability of the tyre. The width of the tyre can affect factors such as traction, weight distribution, and tyre life.

When selecting a tyre for a tractor, it is crucial to consider the specific requirements and applications. For example, radial tyres offer better traction, better weight distribution across the tread width, and a longer tread life, making them a good choice for certain situations. However, bias-ply tyres may be preferred in some cases due to their tougher design and puncture resistance.

It is also important to note that the front and rear tyre sizes on a tractor are not always the same. Most tractors have shorter tyres in the front compared to the rear, and this size ratio needs to be preserved to ensure the tractor sits level. Additionally, for 4x4 tractors, changing this size ratio can destroy the gear train. While the overall tyre height can be changed, it is crucial to change the front and back tyre profiles equally to avoid major damage.

The second number in the standard format is the wheel diameter in inches

Tractor tyre sizes can be written in a variety of formats, including standard and metric. The standard format for tractor tyre sizes is relatively simple but less descriptive than the metric format.

In the standard format, the second number refers to the wheel diameter in inches. For example, in the tractor tyre size "14.9-42", the "42" indicates that the tyre fits a 42-inch diameter wheel. The diameter of the wheel is distinct from the width of the tyre, which is represented by the first number in the standard format.

The standard format can also be expressed with a forward slash, as in "12.4/11-28". In this example, "28" refers to the diameter of the wheel in inches.

It is important to note that the standard format does not provide information on the load index or speed rating of the tyre, which can be found in the metric format.

When replacing tractor tyres, it is crucial to select the appropriate size to ensure compatibility with the gearing and to maintain the correct size ratio between the front and rear tyres, especially for 4x4 tractors.

The metric format for tractor tire sizes is XXX/XXRXX

Tractor tire sizes can be expressed in two ways: the standard format and the metric format. The standard format is relatively simple but not as descriptive as the metric format. For example, "14.9-42" means the tire is 14.9 inches wide and fits a 42-inch diameter wheel.

For example, let's consider the metric tractor tire size "520/85R42." Here, "520" is the width of the tire in millimetres, "85" is the aspect ratio, and "42" is the rim size in inches. The aspect ratio of 85% means that the sidewall height is 85% of the tire's width, or 442mm (520 x 0.85 = 442).

It is important to note that the metric format provides detailed information about the tire, including width, height, wheel size, load index, speed rating, and style code. This extensive information makes ordering tires easier and ensures that you select the appropriate tire for your tractor.

When it comes to the Belarus tractor, sources mention different models with varying tire sizes. For instance, the Belarus 825 model has front tires sized 11.2 x 20, while the rear tires can be 15.5 x 38 or 18.4 x 34. Another model, the Belarus 520, is specified to use ag tires with the size 11.20-20 for both the front and back. It's important to consult the manufacturer's recommendations or a mechanic to ensure the correct tire size for your specific tractor model.
