Is there a shop near you where you can have the wheels calibrated? You will probably have more luck returning a bad wheel than a out-of-balance tire with 200+ miles on it. In addition, this is probably a better place to start looking for an out-of-balance problem. I read pages of reviews before purchasing my last set of tires and this is a problem that dogs big wheels and tires industry-wide. I ended up purchasing Falken Wildpeaks A/T primarily because the most common complaint was the noise generated from the tire, which I could care less about, not tires being out-of-balance. Turns out they're not loud at all. Mine vibrate just a small amount but that's not until 85 or 90 mph so I'm not gonna worry about this. However, the shaking is a common complaint when purchasing bigger tires. I purchased the Falkens because of claims the tread pattern works well in snow and in the sand. I have to admit I've had no problems in either environment. But more to the point here, BFG has a great rep and it is unlikely you received 4 lemons. I'd make sure your wheels are true first then go after each individual tire. Could be you only have one bad apple. Best of luck to you finding the culprit.
