Sheldon recommends always having the good tire on the front. When the rear one wears out it, it goes in the trash, front one goes on the back, new one goes on the front. Ride and repeat. If I'm interpreting your post right, you are, at times, putting the more worn tire in the front. Potentially a bad move.
+1 for putting the new tire in front and throwing away the worn rear tire. More braking, more control.
For my front-wheel-drive car, it's the reverse; the rear tires barely wear at all compared to the fronts. When I wear out the front pair, the rears get moved to the front and the new tires go in the back. In this case, the fronts will still handle braking just as well, but the balance in grip between front & rear will lean towards understeer. Moving the old tires to the back can increase the chances of
oversteer, especially in wet weather, which is significantly hairier, more difficult to correct, and more dangerous.
