    So I've always been of the opinion that sliding the tandems on a trailer doesn't have much of an effect on the drive axel weight. Most of that opinion is because I generally supervise the loading and rarely have to adjust the tandems and never have to adjust the 5th wheel. Yesterday I had a load that changed my mind that I couldn't supervise the loading.

    So I'm on a load a beer from Fairfield CA to Portland OR. They make you scale before and after loading. My empty weight with a full tank of fuel, 5th wheel set 1 hole forward from the back, and the tandems on my reefer slid all the way forward was:

    1. 11,680 steers
    2. 14,060 drives
    3. 8,960 trailer

    So I get loaded and head to the scale to weight. This is with everything in the same position as the empty weight.

    1. 12,000 steers
    2. 33,380 drives
    3. 34,020 trailer
    79,520 total

    I told the guard that I was good with the weights and wanted to get the heck out of there, but she said that I'll need to adjust my trailer to legal weight. I told her that they don't care about 20 pounds, but she insisted. So I left the scale and slid the tandems back 2 holes, which on my trailer is the maximum I can go back and still be legal in California. I headed back to the scale.

    1. 12,080 steers
    2. 34,180 drives
    3. 33,280 trailer

    So 2 holes back on my tandems pushed my drives and steers over the legal max, although I know that I would have made it through without much problems, I was surprised at the results. So I then moved the tandems forward to one hole back from the front, and came up with the following results.

    1. 12,060 steers
    2. 33,760 drives
    3. 33,700 trailer

    Although I was still a little over on the steers, the guard didn't have a problem with it and I was on my way. The weight on this load was supposed to be 42,000 pounds, but since I have the empty and loaded weights, the load weight came out at 44,820.

    Anyway, I just found it interesting and learned something new.

    The guard was right. You can be over 12k on steer axle, but not 34k on tandems.

    There is a max weight stamped on the side of each tire. Most are around 6,250# to 6,500#. That gives you an allowable steer weight of 12,500# to 13,000#. Check your steers to see what weight is embossed on them.

    Guards are a liability to this business.

    They always disallow, deny, say no, or throw you out when you have legitimate business there.

    I remember one I crossed swords with a long time ago. I feel this pinch at the shipping desk and set up to slug the deviant. Only to discover Gramps standing on my foot telling me i needed to check in.

    Now I don't know about you but the shipping office counter has large signs from the false ceiling saying check in here over our heads.

    So I muled it and got stubborn. Told him that is what we are here for. Checking in.

    Since when checking in is not checking in? You hae to get into that truck and drive back out yonder (And leave my assigned dock? With a forklift eyeballing it?) to the entrance gaurd shack.

    Told him been there did that. He said that's why he is here, they let me in on one of his breaks. Not supposed to do that.

    I pulled my black book from the side pocket and entered the facility name, address and reason why I will never be back. And engineered a minor kerfluffle to ensure I banned myself from there which eliminates company questions about any future refusal to go there.

    I unhooked from trailer. (Against rules) drove bobtail to the gaurdshack with him in the passenger seat. Let him out, drive around and pull up at the appropriate window to tell them to get Gramps in here we are doing a very important check in.

    Youngster: "We checked you in a few hours ago" yes you did but Gramps says its not.

    That tied up the gaurdshack as the young one pursued his case with Gramps while traffic accumulated on both ends.

    Called in side. Brought coffee. Set the same on the pitney bowes keypad used to control the truck scale and proceeded to state my case on a federal level with big volume and armwaving as well as getting them to agree that I did this at that time and date and down through the list.

    Phone begins to ring from shipper about my trailer more completely gumming everything up. Muttering and minor cursing is beginning to gather like a distant storm in the waiting area...

    The keypad got a bath from the coffee cup.

    They yelled " Out"

    The entire collective staff in there had one word "Out"

    Out as in go bye bye out? (Applied with some sarcasm...(

    Yes bye bye out. pop pop don't know you anymore. Out.

    Such as a day in a gaurdshack long ago. Thats one job I will not do. Not even for a million.

    You need to check the axle ratings as well. Should be a sticker on the drivers door or the door frame that says what it's rated to. Since I'm Canadian, it's generally either 5,500 kg or 6,000 kg which is 12,125lbs or 13,227 lbs.

    However if your axle is 12K then even if you put on 7000lb tire on there it doesn't mean that you're legal to 14K lbs now. You can only go to whichever point is weakest.

    I would have run it after the 1st adjustment.

    Your full tank of fuel will burn off really quick.

    I'd also slide 5th wheel up 2 notches and leave it there.

    Some of us roam the country with over 12k on the steers. With no hassle.

    My mt weight is 12.8 on the steers.

    The part I dont understand is why did you ever think adjusting your trailer axles didnt effect your drives. Like where did you think that wieght would go??? Just magically dissapeared?
    Everything you do on a truck and trailer being axles or sliders has a effect on other axles. It just dont magically disappear or magically appear.
