When upfitting or modifying a vehicle, these calculations produce information to share with customers, and assist in understanding how certain industry standards may apply - both in spec’ing prior to purchase and after upfitting is complete. If you have a more complicated configuration, or would like to be able to use a graphical interface to calculate axle weight distribution of multiple components at once, please take 2 minutes to watch this video about our Axle Weight Calculator app, or grab a free trial here.NTEA’s Vehicle Center of Gravity and Axle Weight Calculator is a web-based, interactive tool that provides vehicle specification and weight information. We have kept it simple here for purposes of demonstration. The principles of calculating weight distribution are the same for this configuration as for calculating distribution of payload on a truck tractor with one or more trailers. In this example, we have calculated the distribution of weight of a service body over 2 axles of a 4×2 rigid truck. This leaves the remaining weight of 5000 lb – 4322 lb = 678 lb on the front axle.Step 4: Subtract weight on rear from total weight to find weight on front.Step 3: Use the formula to calculate weight on the rear axle.Therefore, we can calculate the Center of Gravity from the front axle to be 208 in – 28.2 in = 179.8 in.Let’s say the total weight of the body is 5000 lb, and its center of gravity is 28.2 in from the rear axle.
Step 2: Determine the weight and center of gravity of the body.In this example, let’s say the wheelbase of the vehicle is 208 in. You will find this on the vehicle specification sheet.To calculate distribution of weight on the front and rear axles of a truck, use these simple formulae: Let’s take an example In this short article, we explain the formulae for calculating axle weights, and take you through a simple example.
