Apply a bead of sealant at the top of the wheel well as a barrier to forceful water and dust penetration from the wheel well into the electrical power and electronics housing.

Silicone bathtub caulk is working for me. In my experience it is easily tearing loose when I need to open the case. I looked for some "H-channel" but couldn't find a source.

Do not clean the surfaces. Or treat at least one surface with a chemically compatible releaser like Armorall. This won't be the last tire you change, so you you want to fill the gap but not adhere permanently.

Mind the anti-spin switch wiring. Brand new my Mten3 had glitchy erratic behavior blamed on this wire being pinched at the factory.

Mind the alignment of the plastic fingers on the power panel.

Mind any other gaps that aren't closing or snapping together, they might be crushing wiring.
