How do I stop my alloy wheels from leaking?
Thoroughly cleaning the buildup of corrosion from the bead area on the rim is an important step whenever a tire is dismounted or mounted on an alloy rim. In addition, tire shops can apply a special sealer to the rim area to help seal the tire bead and prevent future air leaks.
Do Aluminum wheels leak air?
Most cars have alloy rims nowadays. And unlike steel rims, a fair number of these wheels leak air. It’s not a bead-seat surface leak, where air can creep out between the rim and rubber, but a leak through porosities in the cast-aluminum alloy. Then pull the rim out of the water, and demount the tire from the rim.

What to do if your aluminum alloy wheels are leaking?
The first step is to spray soapy water on the tires and find the leak or leaks. Then you can figure out what to do from there. Caddyman July 6, 2016, 2:47am #8 Usually, the leak is where the valve stem is inserted in the rim. Salt gets under the rubber stem and eats out the drilled hole in the metal.
Is it possible for a wheel to leak air?
Any wheel that has a porous spot large enough to leak air obviously isn’t as strong as one that’s properly cast. I’ve had wheels fail structurally at speed, and it’s pretty scary. Heated sideview mirrors are a great convenience.
Can a rim leak cause a flat tire?
Loss of tire pressure caused by corrosion-induced rim leaks can lead to dangerous underinflation. In our part of the country, a large number of customers with alloy wheels are experiencing problems with slow leaks and occasional flat tires caused by rim corrosion (aluminum oxide formation between the bead of the tire and the rim).
