Rim Guard beet juice tire ballast weighs 10.7 pounds per gallon, making it the heaviest noncorrosive liquid ballast available on the market. For a tractor owner deciding how much ballast to add and which fluid to use for ballast, Rim Guard will do the best job of enhancing stability, traction, and pulling power for every gallon pumped into the tire.
Weight density, or pounds of fluid per gallon, is the number that matters when comparing ballast fluids, because it converts directly into usable added weight to your equipment. A fluid that looks cheap per gallon can end up costing more overall if its low density means you need far more volume to hit your target weight. Below, we walk through the physics, run the exact math for common fill volumes, show real weight-added numbers on three top-selling tractors, compare Rim Guard to other fluids, and cover the engineering benchmark tractor owners are trying to hit.
To maximize ballast potential, tires should be filled to 75% capacity, leaving a 25% air cushion for shock absorption and pressure changes. Once you know your fluid's exact weight per gallon, calculating total added axle weight becomes simple math, and you can gain an understanding of how it shifts your tractor's center of gravity.
Water weighs approximately 8.3 pounds per gallon. Rim Guard weighs 10.7 pounds per gallon and adds 2.4 more pounds per gallon than water. Over a 100-gallon rear tire fill, common on a mid-sized utility tractor, that difference works out to 480 additional pounds of stability between both tires, using the exact same tire volume.
This matters most for:
To find your total added weight, multiply your target fill volume (at the recommended 75% capacity) by your fluid's weight. You can find the fill amount for your specific tire size by using the Tire Fill Tool on our website.
Here's what the density of Rim Guard at 10.7 pounds per gallon looks like installed in three of the top-selling tractors in North America:
Rim Guard is the difference between a lightweight and dangerous tractor and one that remains safely planted to the ground while operating under load. On the John Deere 5050E alone, filling both rear tires with Rim Guard adds nearly 1,200 pounds of low-mounted ballast weight. The added weight of Rim Guard works directly toward the ASAE EP562.1 procedure for determining recommended ballast for tractors with loaders, covered below.
Here's how Rim Guard's weight density stacks up against the other fluids tractor owners commonly consider:
Calcium chloride mixture density varies by concentration, ranging from a mild 15% mix at approximately 9.5 pounds per gallon to an extreme-cold 29% mix at 10.7 pounds per gallon.These mixtures carry risks of severe rim and valve stem corrosion, requiring inner tubes. Rim Guard will add the most amount of weight when limited to the volume of your tire without drawbacks of corrosion, flammability, or toxicity like the other options listed.
For loader-equipped tractors, ASAE EP562.1 recommends a minimum of 25%of gross vehicle reaction retained on the rear axle. This is the industry engineering benchmark for reducing rollover risk when running front loader attachments. It's a useful target even outside loader work, since the same weight-distribution physics govern stability on any tractor working on uneven terrain or slopes.
Because Rim Guard packs 10.7 pounds into every gallon, it gets you closer to that 25% rear-axle target with less total fill volume than water, windshield washer fluid, or methanol mixture, all of which require significantly more gallons to add the same weight.
Real-world reference point: Kubota's L2501 operator's manual lists 230–353 pounds of added weight per tire at 75% fill capacity using a calcium chloride/water solution, confirming the scale of weight OEMs expect operators to add. Rim Guard adds 274-310 pounds per tire which is more than a repurposed methanol or windshield washer fluid mixture, and without the corrosion risk that comes with calcium chloride.
How much does Rim Guard beet juice tire ballast weigh per gallon?
Rim Guard weighs exactly 10.7 pounds per gallon.
How much weight does Rim Guard add compared to standard water?
Rim Guard adds roughly 2.4 pounds per gallon more than water (10.7 pounds per gallon vs. 8.3 pounds per gallon), about 29% more usable weight per gallon.
How do I calculate the total weight Rim Guard will add to my tractor tires?
Multiply your target fill volume (at the recommended 75% tire capacity) by 10.7 pounds per gallon. A 100-gallon fill per rear tire adds 1,070 pounds of ballast weight.
How much weight does Rim Guard add to a tractor like a Kubota L3902 or John Deere 5050E?
On a Kubota L3902 (42 gallons per rear tire), Rim Guard adds 449 pounds per tire, or 898 pounds total. On a John Deere 5050E (55 gallons per rear tire), it adds roughly 589 pounds per tire, or 1,178 pounds total.
Is calcium chloride heavier than Rim Guard beet juice tire ballast?
According to the British Columbia Ministry of Agriculture, a standard tire ballast mixture combines roughly 2.4 pounds of calcium chloride per gallon of water, resulting in a total solution weight of 9.5 pounds per gallon. However, because calcium chloride solutions are inherently corrosive to wheels and valve stems and require tubes, many operators are shifting to Rim Guard because it is a non-corrosive alternative.
How much of my tractor's weight should be on the rear axle?
For loader-equipped tractors, ASAE EP562.1 recommends a minimum of 25% of gross vehicle reaction on the rear axle in a static, level-ground condition. Denser liquid ballast like Rim Guard (10.7 pounds per gallon) helps you reach that target with less total fluid volume than lighter alternatives.
Will Rim Guard's weight density change over time or in cold weather?
No. Rim Guard maintains its 10.7 pounds per gallon density and stays liquid down to -35°F, so its weight-density performance doesn't degrade with temperature.
