What was thought behind 12K fronts and 46 rears? It would seem that you would over on the fronts before you got to take advantage of the 46 rears? I am not sure I have seen that combo before.

To be honest I'm not sure, our axle limits are no different than down south. But we do have a lot of mountain passes in BC, and crappy weather, and 132k B-trains, so perhaps it's done strictly for durability reasons (in a GCWR sense).

Either way, the axle capacity to gross combined ratio is much higher on a semi than these new crop of 37,000 lb towing duallies.

I can tell you grossing 100k on a triple axle reefer feels more stable than towing 20k 5th wheel on a dually. You feel the combination is designed for it.
