So, I’ve got an issue that I have been chasing for a while. My truck has had a tire shake or at least that is what it seems like. I have the Beltech 4/6 drop. And it is not a vibration. It is more of a tire shake. I have bout new tires and they are balancing out correctly. It rides smooth until I get to about 65 mph. Then the shake developes. What do you guys think that this could be????

Sounds like possible driveline vibration if it occurs at a specific speed. If it happens when braking from highway speeds your brake rotors are warped.

Don't rule out the tire & wheel possibility. Larger diameter wheels weigh more & GM didn't engineer certain parts for what the aftermarket offers. That extra rolling mass can actually cause a minor vibration even if they are properly balanced. Also, most aftermarket wheels have an oversized center bore hole to fit multiple vehicles with the same bolt pattern. That means 6 wheel studs at each corner have to bear the weight of the truck.

How much weight is on each wheel? Have they rotated the tire on the rim when balancing?

All of the above has been fine except for balancing the drive shaft. It’s weird that it only starts at speeds over 60. Again, it’s a shake and not a vibration.

Make sure the driveshaft is true. Then if tbats not it. Have the axle shafts checked for true

Seen plenty of it , like others have said , driveshafts , brakes , oversides wheels it may be best to bead balance , pitman arms , idler arm , sway bar links or wheel bearings .. Seen some of this come and go even at 30k miles on some trucks.
Its a pain in the ass to to run down. When did it start ? was it after the drop / wheels & tires ? and what stage Beltech kit did you get ?

assuming your suspension and steering components are all good, its most likely from the low pro tires and heavy wheels. either the tires are low quality and/or theyre out of balance slightly. One thing you can try is dropping the air pressure a couple pounds to see if it helps.

another thing you can try is swapping the wheels from the back/front... see if the shake follows. It's all just a process of elimination.
