Thank you all. I can now see how it happened. I took my snow tires off and put my summer tires with rims back on because I got the snows put on to early in the season. The firm that put my winter rims on did not tell me about the centre hub. I am good with my winter rims but will have to take the gaskets off when I put my summers on and get new gaskets when I put my winter rims back on next winter. Thank you all. Nice to have this forum to reach out to when there is a problem. Tesla service could not figure out what I was talking about and wanted me to come in.
