And that rolling diameter changes with speed, sidewall flexing (depending on the tire aspect ratio), bumps that you hit, degree of staggering, etc., etc., etc.
Yes, you may not be getting the AWD light because of your closer calculations, and you may indeed think that there are no problems at all, but the ATTESA systems
is experiencing more wear and tear than it was designed for. Like I said, I spoke with Infiniti engineers who confirmed this - the company that I work for is in the automotive arena (for tracking systems) and we work closely enough with most of the car manufacturers that I have access to the people who should know.
BTW, using staggered wheels on the X model does nothing for handling or ride quality, etc., on our cars. The suspension tuning was designed for identical wheels and tires and, if anything, you are probably reducing some of that design quality and capability.
So, why bother? Like I also said elsewhere, if you want wider wheels and tires, do all four corners on the X model!
Finally, you and anyone else can, of course, choose to do staggered wheels on the X models (and I certainly
cannot tell you to stop!
), but I do hope that if/when you sell your car, the next buyer does not regret the cost of fixing the ATTESA system if/when it dies prematurely.
