What's going on with my tire wear- rears are wearing out in the middle?

Ok, this is an old motorcycle trick.......

If you can SLOWLY drive/push your X through VERY SMALL/THIN sheet of water, when you come out of it, onto the dry concrete (concrete works better then asphalt) you will be able to see the contact patch of your tires.

My guess is the two outside areas of the tire will not make contact with the water or transfer the print to the dry area. Still tho, if this is the case I would not suggest lowering the tire pressure.

Interesting experiment, but I don't see what I can do with it, look below...
