Tire rotation sounds minor, but skipping it can quietly change how your car wears its tires. The tires do different jobs depending on where they sit, so leaving each one in the same position lets some work much harder than others.
That matters most on vehicles where the front tires handle steering, braking, and driving forces at the same time. Over time, the difference can become visible, noticeable from behind the wheel, and expensive at the tire shop.
