Thanks Josh and somewhere back in one of my posts I had mentioned that with my tires being 1/4" taller in front and 1/2" tall in the rear compared to the OEM tires, I should have anywhere between .5 - 1.2 mph lower reading. I had a friend in the car taking screen shots of the speedo app on my phone. I had the cruise control hold the car at 60 mph and 70 mph on as level of a road I could. At 60 mph my phone app read 59.7 mph and at 70 the app read 69.6. I have no idea what it read with the OEM wheels and tires as I never took a reading however I have read that the Mach-E has been tested anywhere between 1 mph too slow to 1 mph too fast.This is gorgeous! By far my favorite I've seen with aftermarket wheels so far. May I ask and sorry if it's been said (I couldn't find it) How far off is your Speedometer compared to gps speed going 70+mph? I imagine it must be a little off given the new diameters are slightly larger than stock
Todd, with the speedo reading less than .5 mph off, I do not plan on having it recalibrated.This is a question I have had too - if you change the wheels and tires on your vehicle, how do you re-calibrate/adjust the speedometer so it is accurate again?
