If you would like to get the maximum life out of your tires, then have
them rotated at every 2nd oil change.
In a front wheel drive car, the front tires will look flat and even, as
far as wear goes. The rear/non-drive tires will develop lumps and pits, if
they are not rotated. This is also dependent on the tire type and quality.
Someone in this thread, said something about being talked into brake pad
replacement, when tires are rotated. When your tires are rotated, this is
the best time to check your brake pads. If you wait until the metal backing
plates hit the rotors, then you will need new rotors (Additional cost).
There should be no extra charge to report brake pad life. It should be
included during the rotation.
When you have the tires rotated, ask them to inspect the brake pads, and
give you an idea of how much pad is left.
