If you really want to mess with it, could you have the tire shop remove the tires, the take the wheels home, clean off the bead area, then paint it and give it several coats of clear on the bead sealing surface to keep it from forming new corrosion? Might hold air after that for a while assuming you can find paint that will stick.
I think you’re probably right Adam, but as long as Walmart doesn’t mind dismounting it and redoing it whenever I have to bring it in, and since that is usually only a once a year problem, I think I’ll just keep taking it back in for a remounting when it happens. Thanks for the suggestion though.
I heard that the reason they even make aluminum wheels or composite in the first place was for better gas mileage because of the weight difference, but I think aluminum sucks and doesn’t add enough to gas mileage to ever want them.
