Hey Guys,
I had to buy a new set of tires so I have to reset my TS in the Gryphon. I went back to the stock tire size of 275/65/18.
Right now with the Gryphon set at 2560, My GPS is showing 2-3 MPH slower than the Speedo. The Gryphon is showing in between the GPS and the Speedo.
Should I increase the MM size and how much?
