My OEM aluminum wheels were chromed by a previous owner and now leak at the rim. What is the best repair?

I had all the the chrome removed from the tire / rim area 1½ years ago. Two wheels have begun leaking again. I'm told the application process embeds the nickel and chrome into the aluminum and will continue to corrode after cleaning. Another "expert" says he puts the wheels on a lathe and mills a few millimeters off at the rim seal to get rid of the contaminated metal. He says he has milled hundreds of wheels like this and has no return of the corrosion. BUT, does this make the rim more likely to fail in some way - ie: fail to secure the tire properly or weaken the wheel?

What is the best way to cure this problem - other than replace the rims?

I think I'd try a tire stop leak (which you may have done already) to help seal between the tire tread and the rim of the wheel, and if that didn't do it I'd replace the wheels. Not sure I want to be flying down the interstate at 75 with rims that had been machined down. One good pothole hit, and could be a serious accident.

I'm very nervous about the removing material from the bead area of the rim. The tire-to-rim interface needs to have the right kind of fit to maintain a safe seal, and cutting away material is likely to loosen that seal. And the rim flange will be thinner, so it will be weakened.

Chroming OEM wheels has another downside that I have personally seen-chromed rim flanges are smoother and more slippery, which allows the tire to rotate relative to the rim under hard acceleration or braking. It's called rim slip, and while the amount isn't much--perhaps an eighth of a turn or so, it distrupts wheel balance and causes vibration. Clip-on wheel weights will move (scratching the rim as they go) or fall off.

Cutting away material will increase the chances of rim slip--another reason not to do it.

I'd buy new wheels and start over.
