The purpose of tire rotation is to extend the lifespan of your tires by allowing them to wear out more or less evenly. There are many factors that cause tires to wear at different speeds: heavier front of the vehicle due to engine positioning and the tire’s role in braking and tire pressure, to name a few. In front-wheel drive cars, front tires tend to wear faster than back tires. When tires are rotated, their position is strategically changed to allow for different traction situations. An easy test for uneven tire wear is to let go off the wheel and check if the car is moving straight. If it’s leaning to one side, you might need tire rotation or steering alignment.
