Very very few shops have the skills to do proper on wheel balancing. I actually buy my tires from 1 shop...drive 30min to my trusted shop to do on wheel balancing, i dont even bother wasting my time with "balancing" at normal tire workshops.

I have a set of badly dented BBS CHR (f***ing PJ potholes), only consistent distinction sifu in OKR can balance it properly, with zero judder even at 180+
