If you replaced the wheels then it can 100% be a bad wheel bearing, they absolutly can cause a vibration. However I would start by moving the tires front to rear first and seeing if that changes anything.
Road Force balencing is a type of balencing, it needs a special very expencive machine (around $9000). But it will tell you if you have a bent rim, a slipped belt or anything else wrong with the tire/wheel it self. If it passes this then it has to be something on the car (wheel bearings, brakes, CV joints, etc)
