I understand the clearence issue, but is this exclusive to the Xterra, and only a few other vehicles.
Tire stores, and chain retailers always say to install chains on all wheels. Naturally it is in their interest to tell us this, but my Nissan, and wife's Hioonda do not allow chains on all wheels.
It seems you cant install chains on all wheels on too many vehicles.

I was just wondering if yuo really can't do it, or if it is just a cover thy butt statement.
