Good day everyone. I'm getting my G37X in a few days and this is my first AWD vehicle. It's an automatic as well. I'm wondering if I can install the Infiniti sports wheels without harming the drive train. I went ahead and bought a set of wheels because they were too good of a deal to pass. The current tires on them are 225/45/19 and 245/40/19 the tread is awful and they both need new tires. I've read and read and read countless back and forth about as long as the difference is under 5% you'll be okay, but some say that changes as the tread life wears down.
