1995 BMW 740 V8 Two Wheel Drive Automatic 236930 miles
my cruise control works for about 10miles and then shuts down and doesnt work again til I restart the car. I have a friend whos' chevy malibu was doing the same thing after he put 20' rims on his car. After he removed them his cruise worked fine. When I brought my bmw it had 18" bmw rims and 245/45/18 tires, could this be the problem or is it a vaccum problem?
