Shaking at 85mph

[Jq42]

Was on the highway today and was cruising around 70 and decided to hit it and noticed as soon as I hit 85mph the car started shaking.

Any suggestions on what could it be?

Unbalanced drive shaft?
Unbalanced wheels?

Take note of the rpms at that speed, drop it down a gear and get it up to the same rpms ( speed doesn't matter) If no shake it's speed related = wheel related.

Probably tires or bent wheel.

Most likely your wheels need balancing. If that doesn't solve it you might have a bent rim(s). Did any wheel/tire work recently? hit any potholes?

I haven't hit any potholes recently. I will try balancing the wheels. Thanks!

Check the vibration thread - your answers are there... it's not tires or rims.
