ok i havent reprogrammed in a few days, ive been running canned lvl2 for daily driving the last time i programmed i did load a 'custom' tune adjusting my tires size to 2470, and set my gears correctly at 3.73...i was curious while i had that menu up so i viewed tire size a cpl times and the gryph kept defaulting to 2472.
i got 2470 from deducting 3% from the mm size i got from the gear ratio prog. im pegasus, i just entered 285/70-17 then took the mm value and decucted 3%. When i program the next time i will NOT deduct the 3% putting me real close to the 2552 you recommended. my stock size was 265/70-17.
Thanks
