Tomorrow I'm going to put some new 19"s on my 350.
Something most of you guys have probably experienced before is when your alloys rust to the Axel and they're an a** to get off.

Is there a special grease to stop this from happening or should I just take the wheels off every 3 months or so and sand the rust off???

 

One time i had a blow out and couldn't get the rim/tire off. I called Mercedes Roadside, they told me to take all but one lug off and shake the car side to side "violently". I was a bit disturbed by the suggestion, but it worked like a charm.
