Front and Rear Axle Weights

Is there a rule-of-thumb for calculating how much weight goes on the front axle and how much goes on the rear axle? As an example; if the 5er weighs 10,000 lbs. and 2000 goes on the hitch, how much would go on each axle?

I know I can take the truck and trailer to a scale and find out exactly, and I'll do that eventually. But for now I'd like to just run some numbers that will be in the ball park.

  • That is perfect information guys, thank you.

    We'll be retiring one year from this coming June. That following fall we are heading out on an extended trip. When we leave I want to have a motorcycle on a front receiver hitch. The bike and carrier won't weigh any more than a typical snow plow, but I wasn't sure how much of the hitch weight transferred to the front axle. Judging from what you all said, I think I'm good to go with plan A.

    You are right on Old-Biscuit, but I'm not sure that is what he is asking. IDK, but if he means how much of the 2,000 lbs pin weight goes on each truck axle, a rule of thumb would be most on the rear axle of truck. Very little weight is transferred to truck front axle. In this case, I'd guess less than 100 lbs.

    We are talking 5er here and even if the hitch is a couple inches ahead of the axle center line, the weight to the front axles is nil.

    That was our experience also pulling a 38' Keystone Montana 3400RL
  • Actually the static weight can be calculated by the downward weight at the pin and then use the distance from pin to rear axle and distance to front axle. The rear gets just about all of it. Now if I could find for old statics book for the formula.

  • Roughly same amount due to -equalizer- that connects the 2 axles leaf springs in the center.

    So 5000# each......but rear can have slightly more weight if 5vr is nose high or front can have slightly more weight if 5vr is nose low or tanks are forward of front axle.
    Side to side can have different weights on same axle due to components inside 5vr.
    so 5000# on axle could be 2700# one side and 2300# other side


    Weight will only give you TOTAL weight on axles (combined) unless you have individual position weighing done

    But any weighing is better than none!!!!
