Wheel/tire vibration and driveshaft vibration occur at different frequencies. A Wheel/tire vibration is usually more of a shake. A driveshaft vibration is more like a buzz, something you feel in your ears. Out of balance or out of round can cause either one. If yours is more like a shake, I'd jack up one wheel at a time just about 1/8" off the ground. Spin it over by hand and watch for variances in the gap to the floor. You can balance an out of round wheel/tire but it will still thump every time it goes around and thus cause a vibration. You can also get a wheel/tire vibration from what is called radial force variation, think of it like a stiff spot in the sidewall which will cause a thump on every revolution as well. Might be worth a simple check prior to hauling the wheels into the tire shop.
