Talk Morgan Forums Community The Malvern Arms Update on GPS Speedo test

DaveW,

I expect the car speedo will have a 2% variation depending on whether the tyres are brand new, or worn to the limit (6mm/300mm=2%)?

...and tyre pressures will have an effect, especially in the Morgans with taller sidewalls?

I expect these variations will exceed the GPS error.
