rooney...I'll say it one time, the modern day radial tire is of such quality they rarely if ever require that much weight, and that includes up to 11x24.5s. Many times it comes down to the installer not having it mounted correctly to the ballancer. "Depends on the situation"...what does that mean? "I've had hundreds of different tires". Well sir, I'm on the wrong side of 70 and spent a life time in the industry and commend you for having acquired that many but to say whatever amount of weight necessary to balance a tire and wheel? Yikes.
