I noticed though that on the website that sells the wheels their is a review from a buyer who purchased these wheels about a year ago,installed them onto a vintage 1970 Airstream and said they are perfect. This being the case ,is their any downside to using a wheel with a 3.50 backset in place of a zero backset wheel ? If yes, could it be done with a spacer ?
Many Thanks Again ,

Are you sure it's 3.50 backset?
I'm guessing you're referring to the 3.5" backspacing on the wheel. This would be the distance from the back of the mounting plate to the outside lip of the wheel's rim. The backspacing of a 15x6 trailer wheel is usually about 3.5".
A '0 Offset' is a synonym for '3.5" backspacing" on a 15x6 wheel. The offset refers to where the mounting pad is set. An offset will make the backspacing of the wheel different than the frontspacing of a wheel because the mounting pad is adjusted.
Take a look at '
The Anatomy Of A Trailer Wheel' to help explain what I'm getting at.
I hope this helps...let me know if you have any other questions.
