Thanks for deciphering my script; yes my question was how am I getting such a difference in my axle weights? Have looked the trailer all over and have not seen any cracks in the frame, but since you said so I'll specifically look for that. There are three valves in a box on the side of the trailer: two manual dump valves (one is possible to be controlled from the cab but not operational that way) and between the two is what looks like an equalizer. I am wondering if that is faulty or if that's possible.
Advantages of a spread axle trailer?

Reason for the spread:
Regular tandem trailers flex in the middle. When going down the road, they flex and bend. This flexing and bending heats up the frame and can eventually cause the metal to crack and fail. A spread axle trailer has an axle towards the center of the trailer. This cuts out alot of the flexing and actually gives a smoother ride.KB3MMX Thanks this. -
On a side note I have seen in the "old days" when we re-arched trailers we would have to install spacer plates on top of the lead axle air bags. But this only happened when we got the arch over 6-7 inches on a 48ft trailer. But most trailers today have little or no arch or the arch is built into the frame.KB3MMX Thanks this. -

Reread my post. Now, where in my post does it say that spread axle trailers dont flex?

Advantages
Easy to load without overloading the tandem
pull straighter atleast too me
Keep the tire dealers in business
disadvantages
keep the tire dealers in business
pain in the arse to back in tight places
They crack worse from draging the axels in a bind
I have also noticed that when u put 40000 over the spread the tires tend to blow worse then a tandem even with the same amount "overloaded tandem" this is my experience but it could be because on my spreads theres always atleast one thats about ready to go. -
Could you explain this with a little more detail? I don't understand why not, if this is possible with the close tandem.
Apologies if this is sarcasm that I am misreading. Jokes are often lost when translated to the computer screen.
EDIT: I do see the smiley, just don't want to pass up the chance to increase my knowledge, even if the knowledge is disguised as a joke.
Thanks.

Ken, the comment about changing gears while turning with a spread axle was meant as a joke with a lot of truth in it. A spread will drag while turning and therefore cause the truck to almost stop or lose momentum, making it difficult to change gears unless you planned to downshift two gears. With a spread, it is necessary to keep the power to the wheels while turning. A driver who operates a tandem every day will be in for a surprise the first time he turns a corner with a spread axle. Most of us do not change gears while turning regardless what type of trailer we have.
KB3MMX, bbechtel16 and KO1927 Thank this. -
