Tire Size not Changing
I've upgraded my tires to 295/70R17s (33.4") and my speedo is reading 9% slow. This is GPS vs what the Gryphon says. I had the same problem when it was the stock edge, I can adjust all the other custom settings, but the speedo is always off no matter what numbers I put it. I've tried from 2500 to 2800 and its always reading slow. ex says I'm doing 55mph while gps shows 60mph...
Any idea how to fix this?
