I have a 2003 E500 which was delivered from the factory with Continental tires. This is the first MB that I have bought new that did not come with Michelin tires. I have noticed that I have to add 5 to 10 pounds of air about every 2 or 3 weeks. All the tires seems to have the same loss of air. I have seen that BMW's are equipped with Continental tires so I assume they are of acceptable quality. My Michelins rarely ever need attention and I can't remember even getting a nail in them much less lose air for no apparent reason.
My first question is has anyone else noticed this phenomenon with their Contentinental tires?
The second question is why did MB change from Michelins?
The third question is where are Continentals made and who is the parent company?
Thanks Rob
