Changing tire size
Changing tire size
I just bought an I1000 tuner and am trying to change the tire size on my 2013 f150 5.0. During the writing process I change the tire size to 35" and also change the enable tire change to "enable". I drove around with my GPS to test the calibration and it was showing over the actual speed on my speedo, by about 5 mph. When I went into the tuner to see if I did something wrong, the tire size selected said 36". I thought maybe I didn't save properly, so I tried it again, with the same result. I can change my axle ratio to the proper 3.55, from 3.31, and it will save. However, my tire size will not change. Why is 36" tires the default anyways???? Someone please help!
