I recently brought my 1997 C36 for what i thought was a faulty cruise control because it never worked above 110 Km. I was shocked o find ou hat i was charged 5 hours of labor. The problem turned out to be that i had the original expedia tires on the front and new Michelin Pilots on the rear. What i was told was that the tire diameters were different so that's why he cruise didn't work above 110 km. Anyone know the truth about his? I was also old hat the computer sense the diameter difference so it won't engage the cruise above 110. It works fine below that.
