You asked and I answered.
I'm not trying to start an argument, I'm trying to understand. I've been a tire guy for over 50 years now. I even managed a tire store for awhile while in my twenties. It's been my experience, on a staggered setup, when there is one axle with a larger OD than the other, that axle is usually the rear. If it's the front, I'm not sure this wont upset the handling dynamics. Please let me know how this works out for you. I also believe the F is undertired, and when I replace I would like to go larger.
I am coming out of a G35 Coupe which came with a 225/45/18 and 245/45/18 staggered setup. I replaced the wheels with wider Nismo forged alloys and the tires with 245/40/18 and 275/40/18. Wider, but kept the OD the same front to rear.
Thanks so much for your thoughts.
