How do you know when to and when not to slide tandems?

It feels weird to me driving with tandems all the way back. Most of the trailers I pull are below 30k lbs...if I pick up a trailer and tandems are all the way back I will slid them

 

At a shipper or receiver it cuts down on springboarding

 

or when you keep hitting ####

 

I just posted it because @Opus loves Orange.

 

Farther back means less weight on the trailer tandems.
Farthest forward puts as much weight on the trailer tandems possible.

 

one thing nobody mentioned ,is when you get loaded over 30K or so, you go to a Cat or other public scale to weigh out.

you will now know what each axle weight is and can proceed to fix as is needed.

scales are found at most truck stops and companies reimburse this expense.

having an atlas or other device that lists the CURRENT axle limits for each state is a must.

 

Do many company trucks have this gauge, or is this something an O/O would install?

 

Thanks for not assuming I know more than I do. Appreciated.
