Since all are "open" differentials, there shouldn't have been any issues. I doubt that the difference in revolutions would have been enough to trigger the traction control. If you haven't committed on the Latitudes yet, I'd recommend the Yokohama YK580s from Discount Tires as a sound alternative. Less expensive, excellent wet road traction, and 60,000 miles tread life warranty. I've had three sets of YK520s, and am on my second set of YK580s without any issues at all.
