low vibration starting at 20 mph to 30 mph sounds like snow tires are on vehicle on 2001 Dodge Durango

low decible noise when reaching 20mph to 30mph sounds like snow tires are on vehicle. So I replaced all four tires. Needed them anyway. Still noisey ride not smooth.

Wheel bearing noise likely. Can drive and make slight steering wheel movement to left and right to help pinpoint which side. If turn left and noise gets louder then the right bearing is suspect because the weight shifts to that bearing and loads it. Or vise versa.

It sounds like a wheel bearing.See if it changes pitch as you cut the wheel left and right while driving (In a safe place of course).
