The "JJ" that you mentioned finding on the wheel size listed for the units mounted to your trailer refer to the contour of the bead seat on the wheel, essentially its shape ( "J" indicates the shape of the letter J). This isn't typically something you need to be worried about in terms of fit when looking at replacement wheels for your trailer or existing tires.

The Dexstar Steel Mini Mod Trailer Wheel part # AM20539 is a 15 by 6 inch wheel like you mentioned needing.
