Newbie - question on rims (need answer today!)
Two additional requirements for a rim are that is must have a 4.25" center bore and a weight capacity of at least 2,600 pounds. The one that poses the greatest difficulty is the center bore, and it is a requirement to insure that the wheel will seat properly against the drum. Try checking with a farm store -- they often carry new trailer wheels in their farm equipment department that would be a much better alternative to anything from an automotive salvage yard.
P.S.: With a tandem axle Airstream, it is permissible to remove one rim and tire in an emergency and travel at low speed for short distances until the flat/blown tire can be repaired/replaced.
