The cheapest thing to try first, is to rotate the tires. If it is tire balance and you put them in the rear of the vehicle, you will feel the vibration chance from the steering wheel to the floor / seat. If it isn't tire balance, then we need to consider a bent rim, a bad tire with a shifted belt, alignment.
LEt me know if it changes.
