    What kind of weight formulas are they using? Surely not federal bridge law. That only allows 42,000 on 8' tridem, or 43,500 on 10' spread. Here in ND, we can put 48,000 on any tridem with duals on all wheels, but have to follow federal bridge on overall length. I can't see how you can put more than 60,000 on a tandem truck, and to put 65,000 on 4 axles the truck would have to be 32' long. 74,000, truck would need be 48' long. I think maybe either I'm misunderstanding what you guys are talking about, or these weights are not accurate.

    That would be handy. :drinkup. Maybe wouldn't have to work as hard. Wonder how much you can put on 7 axles??

    The bridge laws only apply on federally funded roads, which means the interstates basically. My first overweight ticket was in a truck that was legal on the state highways, but too heavy on the interstate.

    Here the most you can possibly put on a tandem truck is as follows: 34,000 on drives, UP TO 20,000 on steer, provided you have 425 rubber, and the truck is long enough.

    Lots of triaxles getting to be more superdumps than quads. I'd say 75% of the tandems are DOT/County/Township. Off the interstate it's 85,500 and no bridge law. Tri can go to 66

    Were allowed about 40k on the drives and up to 20 on the front( with 425s) so long as the gross isn't over 58000 lbs. Lift axles don't fly here, nor do tri drives, but twin steers can go to 75000 lbs. Payloads on tandems are in the 16 ton range, twin steers 22 ish. I'm generalizing the weights a bit because we use metric and I don't feel like doing the coversions from KGs tonight! Lol

    I think Alberta is the same as Manitoba. 17,000 kgs (37,500 lbs) on the drives 23,000 kgs (50,700 lbs) on a tridem. Been about 4 yrs since I had to go out there. Saskatchewan lets you put 18,000 kgs (39,600 lbs) on drives in the winter.

    In Michigan you can run upto 160,000 lbs if you throw enough axles under them. We will load approximately 40 to 43 ton on these depending on the truck and trailer.

    However, were starting to ho to semi's because of the time it takes to break down a double. We can run 28 ton on these legal.
