Well as it turns out my vibration wasn't defective wheels, it was 4 defective Toyo AT2s. Apparently they've had the problem enough lately with the 275/60-20 size that the rep didn't want them replaced with Toyo's. My next choice wasn't available either, so my next next choice was to try out the Falken Wildpeak AT3W.
They run virtually the same height as the Toyo's, so a touch taller than the BFG's. But are virtually the same width as the BFG's, so a touch narrower than the Toyo's. For the price I got them for I'll run them for awhile and replace them if I don't like them, but the first 200kms have been good so far. Don't really hear them, so quieter than the Duratracs. And definitely look more aggressive than the Toyo's.
