What do you mean by "25 pounds or nothing"? Kinda confused

 

Right - who says a sandbag isn't much of a projectile? Like hell! Anything not bolted or secured down is going to go flying in a hard collision, where it ends up is anybody's guess.

 

The leverage effect on the front axle is what he's talking about. You could calculate it using the rear wheels as the fulcrum etc etc.

What my concern is, and it's not a big concern for me as I no longer live in snow country, is the "Moment of inertia":

https://en.wikipedia.org/wiki/Moment_of_inertia

Now y'all can read through all that stuff and do the calculations. Or, if you have lots of extra weight behind the axle and not very prudent in your driving, your "moment of inertia" would be when you discover yourself sideways or backwards at an inopportune time and place.

Spin a barbell with the weights in the center or at the extreme ends. See how that works.

In reality, most people will never have an issue. But the consequences being what they are, I would err on the side of having the weight no further back on over the top of the rear axle.

So in other words you are saying it is best to have weight in front or on top of the axle rather than the back. And when it comes to driving don't swing the *** end out when you step on the accelerator right? And yes my sand bags will be strapped down

 

In front or over the top, that's what I'm saying.

The major issue is to make sure it's secure.

Look it's a popular idea--weight in the winter, haul water in the summer:

Wow, that is a really good idea. Kinda pricey though. I'll probably just stick with the sand bags because I'm a tight *** and won't spend the money. I'll have to come up with a design for the bags to stay in place in case of a sudden stop/jolt and if i get stuck on ice then i can have the sand for traction if needed. At least thats the plan

 

not saying it couldn't happen, just doubt it could

in all honesty I quit using weight in my trucks years ago, just slow down or don't go at all if it's that bad out.

#1 thing is make sure you've got good tires!

 

studded tires on separate rims, used or not, for 2wd winter and your weight will really help out

 

Maybe the problem is what is meant by "projectile", it's what happens in a collision is the problem. Toolboxes, coolers, spare tires, gas cans, blocks of wood, chains etc. **** goes flying. Collisions that were otherwise survivable have been deadly because of objects flying around. A sandbag could definitely **** your day up.

Tom Mix, a huge movie Western actor way back in the day, was killed by a projectile: (Wiki)

"About eighteen miles south of Florence, Arizona, Mix came upon construction barriers at a bridge washed away by a flash flood. Unable to stop in time, his car swerved twice, then overturned in a gully. A large aluminum suitcase containing money, traveler's checks, and jewels, situated on the package shelf behind his head, hurled forward and struck him, breaking his neck. He was 60 years old."

 

Good example

Agreed...that is why I placed one pier immediately for & aft of the wheelwell which essentially balanced the weight directly over the axle.....and yes, I had the piers secured
