I have the Formula rims tree acquired by tires in size ZR 19 to store 255 it. Basically, he can do this well and the construction of the rim tree is done in a minute. He is as described, however very shaky, so that the upper tire loose 20cm can "stagger" left and right. Have the wheels tree therefore fixed with a belt on the carport wall to avoid falling over. There may be more expensive, more stable stand. This one does it but with a little help also.
