Steel or alloy wheels? Both will suffer from rim and/or bead land corrosion to different degrees.

Solution? Get your tyre centre to clean the bead land on the wheel and use bead sealant when fitting or refitting the tyre, my local tyre centre in the UK used to apply bead sealant whether bead lands were corroded or not - the reason when asked why was "We don't want customers suffering bead leaks"

Bead sealant is a liquid rubber compound which dries quickly to a soft rubber and it works very well if applied properly.
