[QUOTE="Twigg, post: 1172232, member: 27619"] Speedometers almost always read optimistically. The amount they "over-read" is variable but usually in the 2 to 4% range. It is better that they are optimistic, as under-reading could well lead to more tickets in these zero-tolerance days. Odometers are usually more accurate than that. In the last odo check, mine was 0.75% over. They can vary depending mainly on the tires fitted as the overall diameter is not identical on tire brands of the same size. Even over-inflation can have a small effect. The GPS advice was good advice. They let you assess more accurately that you are running just over the posted limit, rather than just over plus 4%, which could be problematic. [/QUOTE]
