Have 2 purchased by these rims stands; One with 265/30 9x20 "wheels and 225/35 with a 8.5x19" wheels. Tires are not aufeiander and tight. Rims tree is also very stable and can not tip over without major trauma. The tree was set up quickly, however sluggish with the supplied wrench, here I recommend a socket wrench to tighten the screws (6-kant).
