If you want to rule out a warped wheel, bring you front two tires/rims to a Wheel America shop or other quality wheel repair place and ask them to tell you if the wheels are spinning true. This may cost you some money, but it sure will help you know what is not the problem.

BTW, Discount tire and most mechanic shops cannot or will not do runout tests on wheels for you, and if asked Discount Tire will tell you they didn't see any warping visually (which may be true, but isn't what you need. You need a proper measurement taken on the wheel rim, inside and out, to see if it's oh-so-slightly warped). Even a slightly warped wheel on our cars will cause vibration.

The reason I know all this is that I fought wheel balancing for a bunch of years on my car until I bought new rims and discovered that I had wasted many hours and dollars attempting to rebalance tires and wheels that were warped.
