Q: A: What is front axle reserve capacity, and how do I calculate it? Front axle reserve capacity is the difference between your front GAWR and the front axle weight of your truck with full fuel and passengers. Basically, it's the amount of weight you can add to your front axle before reaching your front GAWR. In order to calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use the following formula: (W x (A + W.B.))/W.B.= Weight the accessory is adding to the front axle. The front axle reserve capacity for your vehicle can be found in the lower right corner of the tire/certification label. Where: W=Weight of added accessory A=Distance that the accessory is in front of the front axle W.B.=Vehicle Wheelbase 4-55
