Replying to: widriver2 (Apr 16, 2008 12:53 pm) I am in agreement that Bimmers should not register inaccurate speeds on the speedometer. The tires that I have on the car are the Conti RFT's and are the correct size for the car. They are not custom. If I had larger or smaller diameter tires and wheels on the car, the yes, I would expect for the speedo to read inacurrately. My '03 4Runner is dead on with the GPS. Don't know why BMW would think it's acceptable to not have an accurate gauge.

hate to beat a dead horse here, but has anyone found a solution to the speedo inaccuracies? Mine reads 4 mph over the real speed at highway speeds. Is there something to adjust w/ the cars computer? I think I know why the 3-series didn't make the "Top 10 Most Ticketed Cars" list, everyone is doing under the speed limit.
