I had the same problem getting somone to balance my F1. and just this last week I noticed it is wearing out-of-round. I first noticied it at higher speeds. (90+) and started looking for the source and one side has worn about 3/32" more than the other(180 degrees in rotation not side to side). still rides smooth as silk below 80 so it realy doesn't bother much. Still tons of tread after 15,000 miles, but I am thinking now I will trade it out this winter. I have a friend that works as a mechanic for GM dealer that says he can balance it. I actually don't mind changin a tire after what will probably 20k. I wil change it at my convience instead of out of necessity.
