I bought the tires stand at Amazon in February and stored 18 inches Mischbreifung him. In April, I then stacked the aluminum 17-inch tires on the tire rack and mixed tires mounted on my car. After about 3 months a foot from the stand star is broken under the tire load without any external assistance. Unfortunately, the whole stand star of very brittle Kunsstsoff. I have since about 10 years a 2nd stand star without complaint in use. At the 2nd stand of foot is completely metallic.
