Vibration in steering and gas pedal

[Juice17]

Purchased a used 2017 ram 1500 Crew cab with 5.7L. 59,938 miles. Around 55mph we feel a vibration In the accelerator and the steering wheel. Below 55 and around 70 mph nothing is felt. Truck came with Goodyear sra 275/60/20. Rotated tires and nothing changed. New tires were installed and road force balanced and truck aligned. No change. Going around corners at speed doesn't matter which way it feels like the tire rotating in steering wheel. Been to the the dealer who has been of no help. Any ideas?

I was going to say an alignment but u said it has been aligned.

Yes dealer aligned it and road forced the tires. Then seemed like they didn't want to be bothered chasing it.

20" chrome clad wheels?

I would be looking at U-joints and CV axles next. I've had ever-so-slight vibrations a couple times and both ended up being U-joints.
