This was discussed on a another thread and I thought discount tires had fixed the problem but it still remains the air is slowing leaking out of my right front rim I was told that it was corroding, I can't afford another rim is there something that Cadillac can do.

I'm very sorry to hear this and would be happy to look into the matter for you. Have you been back to a Cadillac dealer for service after you noticed the leaking was still occurring? Please send me a private message with details on your situation and I will see what options are available.

not sure if I'm allowed to answer in this forum, but I would like to say that I am in the OEM wheel business and am qualified to answer.

Pretty-much, ALL chrome wheels will corrode at the bead, over time. And if your vehicle is a 2007 then it is definitely in the time frame that this would happen. The reason for this corrosion, is that many/most people add air to their tires from gas stations or other compressors that do not trap/evacuate condensation. As-such, moisture becomes trapped in the mounted wheel and corrodes. However, this situation is SO common, and generally-accepted, that procedures and products are in place, just to deal with this. The tire is removed, and the afflicted area is cleaned with a wire brush. Bead sealer is applied, and this properly seals the leak. Happens all the time, everyday.

A new wheel is not needed, just a common address of the matter.

Fret not!

I think I read that bead sealer really damages the chrome and where should I get air. Also is there a specific kind of sealer that should be used

Well, the simple fact, is that there is no such thing as a truly "all-chrome" wheel. Chrome is very brittle and would not tolerate the rigors of use on a car. Most all modern 'chrome' wheels are actually aluminum wheels, with a chrome finish. However chrome will not bond with aluminum. In-fact, it takes 4 different layers to ultimately "chrome" an aluminum wheel, including layers of zinc and nickel.

Not really sure what you're saying about bead-sealer "damaging the chrome". No one really cares what the inside of a wheel (part not visible when a tire is mounted) really looks like when a tire is mounted. But again, this is a very common occurrence, just have the matter properly addressed which includes scrubbing the bead with a wire brush and using bead-sealer to "seal" the tire to the wheel.

You WILL eventually have this problem again even with a new wheel, unless you are vigilant one where/how air is added to your tires.

Where to get air? Well, a venue that has air lines that run vertically up a wall so that the moisture in the lines does not get expelled. Also they should have some form of device that capture moisture. Lastly, they should drain their compressor, daily. See where this is going? Unless you actually work at the venue, or are extremely vigilant, you will fail to adhere to this and some moisture will become trapped inside.

This problem (generally) does not occur with regular aluminum (non chrome finish) wheels, as aluminum does not rust. So your option is to change your wheels to non-chrome. Definitely not a necessary change IMO.

I'd be very surprised if Cadillac buys you a new wheel. Especially on a 2007 model-year vehicle. But frankly, it isn't necessary.

If you aren't getting satisfaction from your local dealer, just find a high-end custom-wheel shop in your area and they will address the matter proper.

I hope I have helped.

At cardio-doc I was thinking the same thing about the inside of the rim I dont really care if it messes up the inside chrome if there's any there to begin with, I was just repeating what someone else in the forum said. Thanks for the info. I'm going to see what Cadillac says they might surprise me and you

Excellent posts, Howard. Thanks for your input!

I think one way to prevent moisture is to use an air compressor that has no tank. I know folks that use tank-less compressors for this reason. Most cars today are getting rid of spare wheels and including these types of compressors in their place.

My shop has two very large compressor vessels that power alot of our equipment. We drain them every day, have two aftercoolers, moisture filters, and we still have moisture in our lines.

You need a refrigerating air dryer. They cool the compressed air below any anticipated dew point and then cycle the output between two dryers that swap back and forth between drying the air and recharging the desiccant. The result is output air with a -40F dewpoint.

I am pretty sure that's what an aftercooler is for. The problem is our pipes are old, and riddled with leaks. In some areas we get dry air. In others we get spittle.

Just left cadillac about the rim and they replaced it free of charge. It's my opinion and I could be wrong but I think it makes all the difference that Cadillac customer service calls for me, I've taken my escalade in twice and haven't had to go in my pocket yet. Thanks Katie

For info purposes, we had this same problem with our 07 Escalade ESV but we have after market rims. To make matters worse they are super expensive (they came on the car when we bought it 6 months ago) - 24 inch Giovanni's. Since they weren't factory- the dealership wasn't an option.

After 3 flat tires in a row (and 1 complete replacement tire) and several different repair places looking at it we got the suggestion to find a rim repair specialist. We found a mobile guy who came out and showed us the corrosion areas under the tire where the chrome coating had flaked or torn off. Those areas were preventing an air tight seal so the tire was slowly going flat. He charged us $50 to grind down those areas on the rim to smooth it out. All of it was interior so it's not visible when the tire is put back on. Problem solved!
