I've never seen this mentioned, so maybe the effect is negligible (+/- 5%) or the system is able to trim out changes in gear ratio. You'd think Nissan would have designed the system that way, since the gear ratio changes slightly as the tires wear. Have you guys ever noticed imperfect rev-matches with new tires?
