Question: If my weight is over on the trailer tandems which way do I slide the tandems? If the weight is over on the drives which way do you slide the tandems? however the total weight is good under 80,000 and the steers are good. Can someone help or give me a rule of thumb? Thank you in advance.

Tandems:

Tandem Axles

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

Sliding the tandems forward will put the tandems further under the load, thus adding more weight on the tandems and taking it off the drives.

Sliding the tandems to the rear, or away from the load, will take weight off the tandems and add more to your drives.

But don't listen to me, I'm a flatbedder with a spread axle.

I would highly suggest taking some time to read up on weight distribution. But a simple and easy to use app for your phone is Trucker's Slide Calc. Shows legal weight per axle with boxes to input your scaled weight. Comes up with a simple hole solution for tandems.

I also suggest Weigh my truck for use with all CAT scales. You input your payment and truck info into the app and every time you stop on a scale just tell the app to weigh you out. It will automatically find your scale, weigh you, and send your request for a print out into the office. It will show your weight on the app + email you a copy.

This way you can weigh, adjust, and confirm without needing to wonder across the lot to get a print out twice.

Last App I suggest is Drivewyze. This app acts as a transponder and will work with any site that uses in-cab notifications (some states don't use, so be mindful) App will tell you in advance if you gotta pull in, bypass, or if you need to follow local signs. Yes, it's legit and legal.

Strayed off topic a bit, but based on context I figured you might want some other helpful tools to make your trucking life easier!

CAT Scale:

A network of over 1,500 certified truck scales across the U.S. and Canada found primarily at truck stops. CAT scales are by far the most trustworthy scales out there.

In fact, CAT Scale offers an unconditional Guarantee:

“If you get an overweight fine from the state after our scale showed your legal, we will immediately check our scale. If our scale is wrong, we will reimburse you for the fine. If our scale is correct, a representative of CAT Scale Company will appear in court with the driver as a witness”

TWIC:

Transportation Worker Identification Credential

Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.

Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.

Easy. Always slide tandems toward the problem.
