If you are sport riding (hard corning) and track riding the tires should be replaced every 2 years. If you are just normal riding 3-4 years. In normal riding you generally replace the front every other rear depending on wear.
If your rear starts to flatten out you will notice a different feel as you lean the bike over as the contact patch will change when you cross from the flattened area to the curved area.
