Re: Wheel Corrosion

I had the same exact issue with my '11 Summit wheels. They replaced all four wheels under warranty last summer.

Re: Wheel Corrosion

The defects that you are seeing on your wheels is called filiform. Filiform corrosion is the term used to describe threadlike lines of corrosion that form on painted metal surfaces. It can occur for multiple reasons and on a variety of wheel finishes, however polished wheels seem to be more prone than a fully painted style. Several factors play a role into the root cause of filiform occurring, it generally isn't the fault of the end user. Surface treatment prior to the final finished layer being applied is key to prevent this from happening. Anytime the clear coat finish is jeopardized the chances of filiform occurring a greatly increased. Temperature and humidity play a major role with how fast it will propagate, as well as what substances are used to treat the roads for climatic weather.

The corrosion starts at a paint defect where the metal is exposed and is driven by osmotic pressure. Soluble metal salts form at the leading edge of the corrosion threads and draw water in from the inactive tail of the threads. The water reacts with the metal to form more metal salts and the system is self propagating. Filiform corrosion pushes up the coating directly above it, giving the appearance of thin raised fingers.

All of the major OEM auto makers have dealt with this issue. If they will not warrant the product I'd recommend having the wheels powder coated or coated in PVD. The cost to polish a wheel is generally more than one would be justified in paying.

Same here too. My 2014 Limited came with the 20 inch Overland wheels. They had filiform corrosion before it was even a year old (thanks for the term Srt8_hmi) especially around the rim and not the normal center cap corrosion that I often see.

A Chrysler Rep happened to be at the dealer when I was there for one of my many recalls, maybe the ORC module. He okayed replacing all four wheels.

When looking at the wheels, he noticed that my brakes were prematurely wearing and warping. He okayed replacing all four rotors, pads and brake caliper service.

I've had the replacement wheels and rotors for two years with no issues.

My 02 JGC had 12 winters worth of driving on WI salted roads. They were pretty beat up by the time I got my 14 and looked very similar to the above pics, only worse.

If the clearcoat finish is in any way compromised by damage caused by tire changers or wheel balancers then moisture or other corrosives can work themselves under the clearcoat. That's how my 02 wheels ended up looking so bad... it was around the outside rim and center hub. Areas not damaged by tire changers/balancers still looked brand new.

BINGO!!

Most automotive wheels are mounted on the balancer shaft through the center of the rim. Then a 'cone' centering bushing is placed over the shaft and through the rim's center hole. When the guy balancing your wheels doesn't lift up the wheel to carefully slide the cone in, the front edge of the steel cone will hit the edge of the rim hole and take a chunk of clearcoat off. Once that happens, corrosion will set in.

I actually had a tire guy put a big 'smile' dent near the center hole on my rim when he lazily mounted it on the balancer. I watched him do it. He denied it, and then I got his manager to buy me a NEW rim at over $400!

I guess the question is, where do you go that the wheel place is careful enough not to do this? Isn't there a certain, touchless machine high-end shops use?

I'd like to know as well. I just went through Discount Tore destroying all four wheels on my wife's Sequoia. Their machine put circular gouges in them through the clear coat and into the aluminum. Luckily I took pictures of them in their parking lot before the install because the first thing out of the managers mouth was "That wasn't caused by us".

Back in Feb I hit something on the road that put a slice in the sidewall of a tire. Had to have the tire replaced. I asked the dealer to be careful as these black wheels scratch just by looking at them. In particular, I asked them to wash the wheel off before they changed the tire as it was pretty gunked up with road salt and sand. Well, they didn't do that.

I get the vehicle back and noticed a major scratch all the way around the wheel... running about where the spokes meet the rim. Kind of a strange location as I would've expected to see that around the edge of the wheel where the tire changer would actually be making contact with the wheel. Surprisingly, not a mark left there.

I'm not familiar with the tire changer they use but I suspect that some part of the tire changer trapped a chunk of salt or sand and ground it into the paint as it went around the wheel.

They have a service that comes in to repair wheels... the guy actually does really nice work. He stated that these gloss black wheels are difficult to fix but he gave it a shot. The service manager told him that if the scratches couldn't be buffed out then he should talk to him before doing anything else with the wheel. The guy didn't do that... he repainted the face of the wheel and clearcoated it. The clearcoat was still tacky when I came to pick up the vehicle that evening. LOL... to make it even worse, the guy took off with my key fob in his pocket.

Now I have a wheel that is full of air bubbles, fisheyes and orange peel. Any light hitting that gloss black surface makes every imperfection stand out like a sore thumb. The service manager is ordering me a new wheel. I just hope they manage not to damage it this time when they put the tire on it.
