It's not so much the actual weight being put on the ground by the tandems themselves, it's more a matter of the axle shafts & gear sets being stout enough to propel the higher gross combination weight without failing from torsional overload.

Alot of MI's road problems is the ground that they are built on, the trucks and weights they run don't help it much either. But I will agree with Roadhog, 75 is alot better than it used to be.

I've never heard of super 40's myself. The thing is with hauling heavy, take it easy and just about any rears will last, same goes for the trans. They may not last as long as super 40's or a heavier duty trans but you can still get by if you have to.

People say the same damn thing about our roads in Manitoba. Mind you we have to deal with a deep frost as well as mushy "gumbo" mud that really gives during the spring. Yet go across the line into North Dakota and they have beautiful roads in comparison.

Hell even the 20 year old roads are nicer than the road they built up here a couple years back.

Are your roads contracted out like those in Alberta?
