Tire size/recalibration


New member
For 37" tires on a 2019 JL, we have recalibrated tire size to 36.61 and up, with the mini taser, but the transmission seems to be slow to shift until 3400 or more RPM. Sometimes it just seems stuck.
The dealer says this is just the tire size and to set it to 37.07 or more. Does anyone else have this issue? At what RPM should it shift if accelerating. It seems to shift gears just fine when going slowly. Of course, if we set it to 37.07 or more the speedometer is not correct.
