I need to better understand what happens when one goes from 15" to 16". Does that wheel & tire size fit the Airstream wheelwells?
Wheel off set has to do with the center line of the wheel in relation to the face of the hub the wheel is mounted on. If the center of the wheel is in line with the hub face it is zero offset. This link might help.

Why would you change from the factory setting? I don't know. Some one that has done so needs to reply here.
INcreaseing the rim size from 15" to 16" may fit. Then again it may not. The whell well clearence is not the same from model to model nor is it the same from year to year. Either you find some one with your year and model that has done this or have the tire dealer experiment when you are there replacing tires and wheels.
BTW never exceed max tire pressure cold inflation from what is stamped on the sidewall of any tire. I usually run my tires at max pressure all of the time.
