I bought two sets for the installation of two sets of tires in the garage and dowelled to the wall. The whole thing is quite unproblematic, sits stably on the wall and the tires are wonderful tidy. The no foam padding causes not much, but at least that is not rubbing metal to metal, which served its purpose, given the weight of a tire.
After installation, I briefly tried a load test with my own weight, which has also been no reason for concern. If it can stand me, then it holds also a tire.
