very bumpy at 70 & 80mph

I just added 22.5 wheels with the semi tires and get terrible vibrations at the higher speeds on the interstate. Someone recommended that I put weight in the bed to see if this helps that the tires are 14-16 ply and there is no weight pushing down on them? will traction bars help? if so who makes them for a 2008 dually?

I don't think traction bars will help with the problem you're having. Weight in the bed may help, but those tires are designed for lots of weight.

Those tires are speed rated at a lot lower speed like under 70 I believe.

What other kind of tires is every one else putting on 22.5? Seems like their would be more threads like this.

Are your vibrations from the front or back?

I am getting them from the front and they are starting to chop. I am having balancing issues, but the backs run perfect. I am only running 50 psi in the rears and 100 psi in the fronts.

Not to hijack, but how are you keeping (if you are) the low tire light off if the minimal psi for the trucks are ser at 65psi. I'm running 50 psi in my tires (rated and smooth as hell at 50) and I can't figure a way to turn off the dam low pressure light.
