How Much Does A Tractor Tire Weigh?
Tractors vary in size, so are tractor tires. An enormous tractor tire weighs from 400 to 600 pounds, which is far heavier than the fattest person on Earth.
You can determine your tire weight by the size of your tractor. Normally, it is divided into 4 groups: compact, medium, large, and extra-large size.
|Tractor tire size
|Tire weight (in pounds)
|Tire weight (in kg)
|Up to 300
|Up to 136
|400 – 800
|181 – 362
Tractor tire size and weight chart
A compact tractor’s tire size ranges between 17.5 feet to 25 feet and has a maximum weight of 300 pounds.
A car tire weighs around 25 pounds, while a light-duty truck’s tire (similar to a tractor) weighs about 200 pounds. So, a compact tractor tire is still 100 pounds heavier than one of a pickup.
The tire of a medium-size or mid-sized tractor is slightly bigger than a compact one, with a width of 20.5 to 25 feet. This tire type can weigh around 400 pounds.
A large-size tractor has a width ranging from 23.5 to 25 feet. So, each tire of this tractor can weigh around 400 to 800 pounds. Some large tractor models have a slightly lighter weight of 550 to 650 pounds.
The weight of tractor tires at this sizable size is the sum of the rubber part and its metal parts and wear patterns.
Extra large size
Tires of extra-large tractors with a width of 26.5 feet are, of course, heaviest compared to the three remaining ones.
An average tire of this tractor can weigh around 1,000 pounds (approximately 453.59 kg). So four tires of this size can add up to about 4,000 pounds to your tractor’s weight.

How Do You Size & Weigh A Tractor Tire?
A tractor tire is too heavy to put on your household scale. So how can you know the exact size and weight?
Fortunately, you don’t have to do the heavy lifting to get this measurement done. Keep looking on the tire’s sidewall until you see a 5-digit number. There is a period between the first two digits and a dash between the third and fourth digits. This number indicates your tractor tire’s size and weight.
For example, the number should look like 16.9-30. ‘16.9’ is your tractor tire’s width, while ‘30’ is the diameter of your tire’s rim. All these specifications are in inches.
Sometimes you have to check your tractor tires based on their three size measurement types – metric, radial, or standard sizes. You can also convert a tractor tire’s size type from one to another.
This measurement type is widely used in Europe based on the European measurement system. For example, 520/85R42 or 420/85R24.
You can read its meaning from left to right as follows:
- “520”: your tractor tire’s width when it’s properly inflated or mounted. Sometimes this number is small, meaning that it is presented in millimeters instead of inches.
- “85”: the aspect ratio in millimeters. The ratio indicates the tractor tire’s width percentage to its height when it’s properly inflated and mounted.
- “R”: indicates that your tire has radial construction.
- “20”: the wheel diameter for mounting.
Radial tractor tires are widely used in most tractors on the market. This tire type uses radial construction because the tire has 90-degree cord piles inside, moving in the same direction as your tire.
A radial tractor tire has two digits with a period in between, the letter “R” stands for “radical construction”) and two digits after that.
For example, the size and weight of a radial tractor tire are shown as 11.2R20 or 18.4R26.
The first example in this section is called standard measurements for a tractor tire. There is another alternative expression of this measurement type, like 11.2X20 or 16.9X28.
Conversion between these three sizes is possible. You can look at this Ken John Tires conversion chart for size equivalent.
Tips To Make Your Tractor Tires Last Longer
The best Tractor tires are so expensive and critical to your tractor that you don’t want to waste the tire replacement budget over time.
Therefore, you should frequently check and maintain your tractor/combine tires anytime you don’t use them. Let’s look at some valuable tips to extend your tractor tire’s longevity and performance.
Keep them clean
The first and simplest way to keep your tractor tires in good condition keeps them always clean and free of gunk.
Gunk includes brake dust, road grime, and dirt. While your tractor is in its working mode, gunk can easily stick on it.
If gunk stays on tires for a long time, it can cause harm to the tires. After using the vehicle, you should remove all this dirt out with soap, water, and a high-quality tire brush.
Then wipe the tires and let them dry naturally.
Store at airtight places
You should store your tractor tire in airtight places to prevent the evaporation of the lubricating oil within the tire.
You can get high-quality airtight plastic bags like garden or lawn bags from a tractor tire supply store in your neighborhood. When placing the tire in these bags, remember to get as much air out as possible, then secure the bag with tapes.
Place them upright
You should store your replacement tractor tires upright, not stacked or lying down. In case you have to stack them, please don’t stack them too high. Otherwise, they might fall and be damaged.
When storing your tractor tires, the critical point is that you should keep them in a cool and dry place and avoid direct sunlight. Black tires can absorb the sun’s rays and be heated up to 120oF. At this high temperature, it can break down or cause wear and tears inside.
