The wheel rating should be a minimum of 2600 pounds.
Wheels take a huge beating when used on a tandem or tri-axle trailer.
Everytime you make a turn, those wheels received tremendous side pressures.
Make a turn in a parking lot and stop the rig, while in that turn. Look at how much the tires are twisting. That is what applies those side forces.
Just because a wheel may fit, does not make it useful, unless it's proper rated, except in an absolute emergency, where caution and safety are tossed to the wind.
For short distances, in fact you don't need a spare, as your Airstream will handle just fine at low speeds, with only 3 tires in use.
