Yeah I know. That's why I'm concern about the safety of too thick adapter. Unfortunately I was able to find only one company selling these adapters and only 20mm size which I'm not happy about at all. But it's literally the only company I found which doesn't ask $400.

If someone has contact where I can get some for reasonable price pls let me know.
I need them asap. The wheels in the corner of the garage are making me crazy
