X chock problem solved. After messing with the wrench and getting past a stuck point, i was able to collapse the device small enough to get in between the tires. I guess the bonus is I barely have to open it to firm it up to the tires.
Glad you figured it out. I WAS going say that your pic didn't look like it was fully collapsed. (I store mine in the box they came in; I HAVE to close them all the way to get them back into the box.)
