Wore out three sets of tires already!
I size my chains by having the cage & jockey wheels canted forward & down at about a 45 degree angle when in the big-big combination.
I don't think I've ever had a problem with doing it that way.
Another thing to watch for is the ability of the derailleur body itself being able to pivot back & forth at the attachment to the mounting claw.
I see a lot of pics of these derailleurs where the body is canted back, showing that it's locked up tight at that location.
It can be a finicky adjustment to make to get all the side to side slop out, but still retain the ability to pivot.
There are stops built in that restrict how far the body can pivot both forward and back.
