Edge/Gryphon owners. Need code help.

Anyone know the tire code for 285/75 16 that you enter into the tuner? Its in the book, under the tire codes. I just can't find my book. Any help is appreciated.

The "book" value would be: 2619 mm, but that doesn't account for tire "squish". I've found a 3% squish factor works for me, so I'd change it to 2619 x 0.97 = 2540mm. Use that as a starting point. If your indicated speed is too high, reduce it, if too low, increase it.

In my case I started at 3% squish and jumped all over then finally found that 2848 (can't remember the % value of squish off the top of my head) is about 1mph off on the speedo.

Thanks for the replys. Had a road trip, and wanted to make sure I had the right code in, and I couldn't find my book.
I went inbetween the 3% squish and the book number, and got it within 1 from my gps mph, so thats good enough for me.

Thanks for the help
