Are you a nissan tech/engineer? I notice you posting a lot of technical and functional info that leads me to believe you might have more knowledge than the typical owner.
No, I'm not an engineer... just an avid Nissan owner for 20+ years. I have accumulated a lot of knowledge in that time wrenching on my own cars... whether I was driving them everyday or on the racetrack with my 240SX. When members post questions here, I try to take the time to research them using the resources here on NICO, Factory Service Manuals, etc. My wife says I'm obsessed!
Anyways, back to the topic at hand....
The ABS, VDC, traction control, and AWD systems use the wheel speed sensors located at each wheel. There is some leeway for tire inflation, sizes, etc... but go to far and you might cause issues. There are many systems in the Rogue that use vehicle speed to trigger certain sequences... ie ABS self test, AWD Lock inhibit at high speed, Traction Control, etc. These systems depend on accurate speeds for control.
Now, something up to a 2-3% difference probably wouldn't cause an issue. However, if you were to go 15-20% oversize... I suspect there may be some problems.
BTW, the odometer and speedometer in the Rogue get their readings electronically from the wheel speed sensors. That's right, there is NO speedometer cable! There is also no way to correct for speedometer/odometer error from running oversize tires.
