My most recent mount/balance included a road force balance. The worst wheel/tire was about 17 lbs unbalanced weight, which is apparently well within spec. Would this technique identify a warped rim? Maybe I should track down a local CEG'r and do a 4 wheel swap just to be sure. Thanks for the suggestion.
