I am not sure if this topic has been addressed but I could not find any postings on it. I was at my local dealer the other day . I trust them for all my service needs and they have always done right by me. We got into a discussion of using nitrogen in the wings tires. They feel there it is beneficial for a number of reasons, one is the ability of keeping a stable pressure in the tires and the other is they have experienced substantial increase in tire life. I am curious if anyone is using nitrogen dew have you noticed any benefits.
