He has balanced the tires twice now . On a spin balancer . I told him call Hoosier and see if he did something wrong . Maybe they can only be bubble balanced ? Or maybe something wrong with these tires. They take 9-10oz to balance .even tried moving them around on the rim [/quote]

If I had a tire that HAD to have that much weight....I'd throw it out. [/quote]

Apparently you've never balanced a bias ply slick
