AEV pintler wheel weights?
I believe you are thinking of Centramatic wheel balancing system. I had them on my TJ and the worked great. You never have to balance your wheels again, which is especially nice when you have trailed your rig, aired down and perhaps have had the tire walk slightly on the rim, or you chunked your tire, or just have rocks stuck in the treads or mud on the inside of the rims.
If you only have weights on the inside, then the wheels were not dynamically balanced. Dynamic balance requires wieghts on both the inside and the outside of the wheel. It balalnces the wheel horizontally as well as verically. Dynamic balancing is not the same as a spin balance.
No more buisness with them! And they aired me up to 45 PSI!
