would I get a ticket?

I think the engineers hope for no more then 500 lbs difference and perhaps strive for even less disparity, but the systems are rather complex and sensitive and susceptible to issues that can cause a wider disparity then one would like and the 1,000 lbs is probably closer to the average on the road today, then 500 lbs is. just because the systems are fallible and easy to get out of optimal adjustment.

 

The load is 12ft long. C (center of load) is 5 ft from one end, 7ft from the other. We'll go with 47000. You need to move 4000 lbs. 470000lbs/12ft= 3917. So every foot foward or rear moves 3917 lbs.

 

Not for 52000lbs. The trailer should be strong enough.

Some states will only give you 40000/axle with a non-divisible load. Some will give you quite a bit more. I'd worry about cooking the tires before breaking that trailer with 52k.

Anyways, keep up the good work.

 

i can't remember who, i think it was texan. that posted some math on figuring out the center point. i think it was kingpin to center of spread axles and the math come up to 2 feet forward of center. i think it's this thread.

so you'd want 22 feet front half and 26 feet back half on a 48. i've always just gone with the turn signal or marker light which is the half way mark. 24 front and 24 rear. loads are usually close enough to not worry about it. at the most it's been 1000 more on the trailer. but when you load with a lot of NON english speaking. they only understand the hand pointing at the light.

as for the 52,000 pounds. that's maximum allowed legal weight on 48 spreads. if one was to max out their axle weights. but you'd need overweight permits. depending on the actual weight and states your running. for instance, colorado allows 86,000 pounds. but you have to run the secondaries and stay off the highways. wyoming will allow you to register for whatever weight and you can haul that without permits. 84,000 being the typical max for a standard axle axle setup.

 

some like to run with steers at that 1,400 weight in the picture to save on wear and tear on the steers. but your shorting yourself 1000 pounds on the drives. no big deal for those of us running spread axles. but can be a big deal for closed tandems.(think, 68,000 lbs. total weight between drives and trailer axles.

some of us are running 12,400 on steers with full tanks. if the truck is rated you can go up to 13,000. i've actually had to use the excess allowed weight twice on my new truck. as the drives were too heavy.
