I'm not sure if this will work for what you are trying to accomplish but why not use one of the same wheels off the right side if they are the same tread design, etc? Keeps you from using the spare and lifting with a jack if blocked up.
Otherwise, remove the front tire and replace with the spare. Now block the front and remove the rear, putting the original front tire on the back. Now block up the back again and put the original rear tire now on the front. Put the spare back under the trailer and you don't have to use a jack or the right side tires.
