I think you should follow that advice, no mods, use the stock tire size and get an extended warranty. I have a 05' with 20k on it now and used it for light off-road and snow driving. No issues yet but I'm going to get a 7 year 100k warranty just in case. I think that your not seeing everyone having the problem, it seems like the guys doing the really hard off-roading with big tires are having most of the problems.

If this keeps us Nissan is going to have a very expensive recall.
