    I have 430 wheels on my 360 and notice no difference. I did notice that my speedo states 8mph faster than what my GPS shows. This remains unchanged even with the 430 wheels

    I have seen no difference on my 360. The F430 rims with the recommended tires are the same height as my old Facory 360 Rims and so I assume there is no difference in MPH. Your GPS is not accurate as far as speed and should not be used to figure out anything other than how to get places.

    On the contrary, a GPS unit should give highly accurate speed readings, far more so than the typical over-reading provided by enthusiastic speedos!

    Your speedo changes only if the diameter of the wheel/tire combo changes.

    Sorry, what I meant was the F430 rims with the recommended tires are the same height as my old factory 360 rims and tires. The diameter is the same on both sets.

    How do you figure your speedo to be more accurate than a triangulation of coordinates between at least 3 satellites and a vehicle equiped with a receiver to measure information received from all the above.

    There are many tire size calculator apps and online ones are free. Give it a try
