I had an oil change done at the freighliner dealership and they inflated the tires to 70 psi which definitely improved the ride.
I do have koni fsd in the read so no adjustments needed, I did notice the ride improve over time.
I noticed a slight vibration in the steering wheel at speed above 70 mph but it's not always present.
The tires were just installed and balanced by sts tires which specializes in cars/small trucks. I was thinking of doing a front wheel alignment and front wheel balancing at a truck alignment shop.
Hoping that would improve the ride
