There is obviously NO one time download for increasing tire sizes on our trucks(speedo calibration, shift points etc). However I was talking to a person the other day that stated it may be possible to adjust tire revolutions per mile, with the tech II. I dont know if anyone here is really good with the T-II, But could this be true?. (i.e. Lets say a 245-75 tire has 780rp mile, Can T-II finagle in 760 rpm for a 265 tire?) I was told this by a person who was "fairly" knowledgeable in our trucks.....but on speaking with a SM he didnt recall ever seeing this option or I guess program in T-II. It would seem if its true JK would be all over it. TIA Bill
