Not entirely true. Front wheel drive cars wear out the front tires
significantly faster than it's rear tires. You'll be replacing the
front tires at nearly a ratio of 2:1 in comparison to the rear tires.
The reverse holds true for rear wheel cars (of which many cars are
still made that way).
Rotate them and you'll get longer life out of all four tires.
Otherwise, you'll be constantly changing a set of tires. And many
manufacturers don't make the same exact tire every year. You'll
end up with two different sets of treads and/or manufacturers if you
constantly only buy one set of tires.
Also, maybe you mean moving front to back/back to front but you don't
actually take the tires off the *rims* when you rotate. You merely
move the entire tire/rim as a single unit.
However, as you mentioned, if the front and rear tires are of
different sizes, the ONLY rotation you can do is left/right and not
front/back.
