From my research, there does not seem to be any way to recalibrate a 2014 Grand Cherokee's speedometer. It does seem like, in the future, there might be a way though. For the 2013 Jeep Grand Cherokee, there is a way, it's some tuning tool like SUPER CHIPS. Using this tool may VOID your warranty, so know what you're getting into. Also, it seems that a Jeep Dealer will not perform any calibration different from an OEM size.
From this research I have decided not to use other than the OEM size.
I have had my speedometer off on my current vehicle for many years and would like it accurate now.
Jeep does authorize after market rims and tires that meet the OEM specified size. (I don't remember where I read this though.)
