Incorrect title... Since it was about, Leaking "Chromed" Aluminum Alloy Wheels.... Due to Galvanic Corrosion from the chroming process layers of metals being in contact with the Aluminum..... Not regular Alloy Wheels.... While non-chromed aluminum Alloy Wheels are protected by Aluminum oxide layer, that chromed Aluminum is removed by Galvanic Corrosion ... FWIWand moisture (ie water) with electrolytes in it, just accelerate the corrosion but is not the cause... Solution is simply, do not buy or use "Chromed" Alloy Wheels.... KISS... But if you do have them, wax them and keep the very clean.... Corrosion is accelerated when dirt and moisture from any part of the wheel is present especially of they are scratched.... But they are never a good idea, since they are a problem waiting to happen....
I have those exact same wheels on my Yukon with that exact issue. Tires lose pressure every few days - especially in the cold. I've had the tires remounted with a bead surface cleaning several times to try to extend the life of them. However, they have reached the end of their useful life after 14 years. Too risky to keep them - especially when you tow. I've already planned to replace the wheels this summer. Too bad that this occurs - I like the looks of these wheels. I will be replacing with similar aftermarket wheels that are not chrome plated.
You're wrong. Just had this problem with the alloys on my 2013 Mazda CX 5. Took two trips to Costco to fix the problem which was due to corrosion. Strange part is nitrogen is suppose to keep this from happening,guess not.
Hi, very helpful. However, I have 2018 Mercedes and for the last year one of the rims leaks severely. MB said not under warranty . No screws or nails. Thinking of putting in tire sealant. Thank you
Mercedes rims are very susceptible to cracking, usually on the backside lip of the wheel. Potholes or railroad tracks will do it. We see them alot at the tire shop.
Costco cleaned mine twice First trip they fixed one but the other was still slowly leaking from 34 psi to 27 psi . Second trip seems to have fixed it and both times they used a sealant along the beed. Vehicle has been on the road for 9 years in Pennsylvania, surprised they lasted this long.

Yup my 2011 Tahoe LTZ has this going on. Chunks of the wheel are peeling off the backside of the rim.
Interesting information. I will check one set of wheels I have for this issue.
Good to see your back again 👍
My 2006 mercury mountaineer premier rims leaked air all the time! I just went out and bought 4 used steel rims and never had a problem after that.
Good thing about steelies, if ya bend one a little you can hammer it back mostly right.
On non chrome wheels this is not much of a problem from my understanding. Mostly chrome wheels. Correct me if I am wrong.
Not as much but any wheel for most part can get corrosion.

Don't use sealant. It will ruin your TPMS sensor AND the tire shop will curse you when they have to clean it up.
Happens alotwith GM vehicles... Chevy Equinox, am I right
If after wire brushing didn't fix a leak like this I'd throw a little axle grease around the leaky area.
How does axle grease hold up to the air pressure? Not very well, I’m thinking. I’m wondering about some kind of spray on epoxy paint, maybe.

Aftermarket wheels almost always lead to tire pressure issues.
GM keeping tire shops busy
Bad castings on the GM wheels, I have welded more than a dozen of them
You would think, in this day and age of manufacturing technology, wheel manufacturers would have already solved this problem! I'm a victim as well.
It's a GMC wheel. I'm surprised it's even in one piece.
I bet it’s a lot of salty roads where they live
What is with motorweek presenters and the over pronounced “whu” sound when the say w
I hope people are not driving on expensive alloy rims in the Salt Belt in wintertime.
@Discofelsi Some of us swap them out for winter tires on steel rims :)
