I thought cupping was due to out of balance

Get a new pair of shocks and a alignment. Im sure that will correct your issues.
Manufacture alignment tolerances are " with in " and OE shocks suck, poor quality. New shocks and an alignment should be the first thing all buyers should so

If you tow frequently, that will exaggerate all of the above issues. Towing will sometimes cause porposing and create the illusion of bad shocks and could cause the cupping.

I have a set of these balancers on my F450, they are fantastic. removed the wheel weights on the outer aluminum wheels and it drives smooth as silk.

My tires in my old F350 cupped because I had poor shocks and I did not rotate them. Only 20k miles, tires were TOAST.

I left the weights on the inner rear for now, my concern was corrosion on the aluminum rims, going forward w/ new tires I wont balance anything prior to installation. Other than a slight "wooshing" sound if you stand next to the tires, I don't hear anything from the cab.

What tires are they ?
I have stock Conti's and had outer wear by 2k and cupping st 4k. They warrantied the tires and supposedly did a road force balance.
NOT a dually and this is on the fronts

thanks for all the info my really is checking it out but i did notice now that i think of it a bounce in front at times when i changed to dually. so i have aired up to full 80 psi in front and that has gone away now i will put those tires in back. In meantime my dealer is great for taking care of me, so will see what they come up with. Apparently Talking with a trucker friend they're front steer tires have same issues even if low on pressure 5 10 lbs.

Agreed!! I replaced my shocks w/Bilstein 4600 and with rotations, I have 38k on my original Michelin's. Hoping to get 45K+ out of them
