I have read several posts about going to 37" tires from the stock 35" tires. One question I have relates to the computer and the speedometer readings. Obviously the speedometer will be off by more than 5% when the larger tires are installed. What have those of you that converted to 37" tires done to correct this as the speedometer also impacts shift points and the computer? I know on our Jeep Rubicon we needed a programmer to change the tire size (and gear ratios), is that the same for the Gen 2 Raptors...Thanks!
