The only time I had an issue (with 16" Michelins) was when I didn't get the rear one shoved firmly under the rear tire. When I went to back off the rear one snagged the front tire a bit. No harm, no foul. I may trim off 1" or so, but I am not sure it is necessary, yet.

Honestly, I do not have more than 5 or 6 tries with them so far. Even so I've had no problems with them. One thing that someone suggested is to pull forward onto them instead of backing up on them. I plan to try it next time. I believe that with the propride, it may help to straighten out the hitch a bit before disconnecting.
