Weight distribution

Your rear axles are also carrying weight from what you put over your landing gear and what you put in the middle.

 

Gotcha .. if you loadung coils that kinda makes it alittle easer to figure.. I I would try moving my front coil fwd alittle to get more weight on your steer & drives

 

The 2 11.5’s should have been over the front trailer axel. That would have pretty much centered the load.

A 48ft flat is simple.. Sure u can bypass the scales but during winter time if ur pulling a mountain and ur already 15k+ more weight on the trailer and u start pulling a mountain. Gravity is going to pull a lot of that weight back towards the trailer and u risk breaking traction on drives.. It can even happen in rain on a big Mountain. I have learned that 1 the hard way... next time if u have multiple coils put the heaviest 1 in the middle and build the others around it... use your light in the middle of your trailer as a reference..that is most likely your centerpoint on your trailer. Calculate how much weight you have in front of your light and how much weight in back of your light.. And they have to be evenly spaced from the middle. Don't move stuff to landing gear and then the stuff on back of the trailer all the way to the back.. Its going to make you heavy on trailer axles every time... if u are new to flatbed just get a good idea by loading everything in the center.. Once you start to understand it then u can start playing around with loading stuff in different spots.

 

Why are we using the landing gear as a reference? You kingpin and trailer tandems are the load points.

 

Yes it would put more weight on the drives. Why run around with the trailer almost maxed out on weight when you got all kinds of room on the drives.

 

You’re overthinking this. Put them all together in the middle. From the front 11.5,11.5,20,7 with the light between the second and third coil. Maybe move the group forward 6”-1’ forward of centered on the light. If you want to split load it move the rear two and the front two equal distance away from the center point. For example move both groups 12’ away from the light.
