The worst tires I had as far as balancing were Ecopias IIRC they had small internal ribs that I think the counteract pellets would get caught on and not balance out if I hit a good pot hole in that 10-15 mph range and wouldn't go away till the next stop. The larger size of BB's they may not even notice those ribs.

I have used them in 6 cars for combined +300,000 miles. Largest tire 226-60-16, mostly 196-65-15. Haven't had a shop mount a tire since the Suburban before the Impala as I didn't want to do that size of tire on the Harbor Freight Changer.

On the 2 Cobalts and Impala I add 1.5 oz of stick on lead opposite the valve stem/tpms sensor, before doing that they didn't seem to balance out quite as well. Didn't at first but learned it worked better with a little lead. Close to 200,000 miles with counteract beads on those 3 cars alone.

Put 800 miles on the Impala Saturday and it occasionally doesn't balance out perfect, it has Nitto Sn2 winter shoes on it yet and don't recall what the inside surface is like.
