You should be buying food and rotating tyres as a natural response to
life in general. Both are necessary.

Not everyone recommends rotation. It's not even possible on some
vehicles. Just replace them in pairs as they wear out. I've personally
never rotated my tires on any car, but that's admittedly just my
choice. In fact, on the car we're talking about, the feathered tires
are probably noisy anyway, so she'd just be moving the noise to the
back, where it might be even worse.
