Dunno.  Maybe not.  But I've sworn to all my gods to only live with five
equal tires and to use all five of them as  equally as possible.  And to
make sure tire pressure is correct.  In my humble opinion a bad thing to
do is  to have pretty worn  tires and a   brand new spare.   Well, to be
precise ... this in itself isn't bad at all ... but  only as long as you
successfully manage to prevent a puncture ... :-)
