How much weight can tires and chassis handle?

Note: These trucks were one of the military's most rolled trucks. They can be overloaded as any truck but if you want reasonable safety and off-road capacity don't go much over the spec's. Dualies are more capable than singles for overloading, but there is more to it than tire or axle rating. The frame and springsets can also be the limiting factor. I wouldn't even think of going over 3200 gal for that truck and even that is high. I have seen a couple of these trucks converted with a tank for Utah's forestry firefighting roll over with all that weight high above the wheels. Whatever you do, find a tank that sits as low as possible on the frame and baffles are a must... I will ask Murl at the forestry service the next time I talk with him, to what size of tanks they finally went with...

You are quoting the bridge law for the 12k and 34k for a tractor trailer. This changes based on axle spacing. With a permit you can exceed this. When I was driving we used to scale at 60k for a three axle. I have a friends that legally weigh 70k on a properly specified straight dump truck.

The 44k is design capacity and is very common on construction trucks.

This application is for off highway.

Ya and?

Your information is based on highway use and is not relevant to this application.

This application is for what the vehicle can carry on a farm.

The real limiting factor here will be the design capacity of the drive train, suspension, tires and the frame.

These trucks do not have a extreme duty frame. This could be a heavy frame or a double or triple frame.

If the OP really wants to max it out he should look for a civilian truck with 58K rears in it.
