Tire question

So, the annual is done, and I came out easy (again!) -- just two tires and a
brake hose. (Knock on wood. They're still installing the landing lights,
so I s'pose they could still find something else...)

Although I'm replacing both tires, really only the right tire was bad. It
had five bald spots, while the left tire was still pretty good -- a bit more
worn on one side than the other, but that's pretty normal.

Question: Any clues what could cause one tire to wear dramatically faster
than the other? (They were "Monster" retreads, BTW, which are highly
recommended by my shop for long life.)

Note: When we park the plane at our hangar, we must pivot the plane sharply
on its LEFT tire, by locking that brake and turning as sharply as possible,
to position it for pushing back -- yet it was the RIGHT tire that
prematurely (IMHO) wore out.
