With time the bead on alloy wheel becomes corroded which impact the proper sealing of the tire. The wheel starts to loose air slowly so you have to
pump it every other day or so. It will get worse especially in cold season. Such wheel must be fixed properly. Applying of the liquid rubber, glue or silicon will not help (and this is what most of the shops doing). The corrosion has to be removed completely and properly from the wheel. The picture shows the bead before and after cleaning the corrosion. But even cleaning is not enough. The wheel has to be protected. In our shop after removing the corrosion from the wheel we also apply special oil based chemical to prevent the wheel from corrosion in the future. Only after that we will mount the tire back. We give 6 month warranty on this job, but in reality those wheels will not give you a trouble for years.
