Why it should be done: Tires wear eventually, tread starts to become thin, which will result in the used wheel losing traction. This creates safety risks that can be avoided. Manufactures suggest tires need to not be used for longer than 10 years. Changing wheels is advised every 6 years, however with typical use tires being changed every few years is more likely. Wear happens with regular driving. Various other factors such as driving habits, roadway conditions and weather can easily reduce the life of your tires.
