Steering Wheel Vibration (56-65mph)

Hello everyone, I am recently noticing the steering wheel vibrate on the highway. I attached a video. It seems fine below 55ish mph and gets worse at 57-60mph and goes away completely after 65mph. Any ideas?

 

I have to run specific tire pressure (50lbs) or I get a vibration around the same speed. Might be something to play around with ?

 

Get tires balanced, ensure proper air pressure. It could also need alignment. Those are the 3 things to check/tackle first as tundras are sensitive to each of those things being off and can shimmy if these things are off spec.
I get my tires balanced/rotated every 5k miles around the oil change and it makes a big difference in any shimmy. It is probably tire balance.

 

Thanks. I will start there.

 

Get a road force balance. Fixed the vibration I had after getting new tires.

 

50 PSI? Cold?

 

road force balance and make sure they put weights on the inner & outer of the wheel inside.

i have to road force every 5-7k, otherwise i get the steering wheel shimmy between 55 & 60mph.

i believe this to be caused by side to side vibration, and weights placed as pictured below resolves that.

 

Wheel bearing going bad?

 

Not quite. I live in Texas.
