Rotating your tyres will extend their lifetime and improve their performance. Tyres wear out differently based on where they are located in your vehicle. Front-wheeled driven vehicles use the front tyres to generate power and so will naturally wear out faster than the rear wheels. Likewise, rear-wheeled-driven vehicles will wear out faster than the front wheels. For all-wheel-driven vehicles, you can rotate the wheels in a crisscross pattern with your left front tyre going to the right rear, the right rear to the left front, and so on.
