Changing the tyres on a car is important for a person who drives to know. You never know when or where you might have a flat tyre. You could be in a location where road service is not available. Sometimes, you are in a hurry. That is when road service tells you that there are five other calls in front of yours, so you will need to wait a few hours. If you live in a location with harsh winters, you may need to change all four wheels every Autumn for better traction and every Spring for better mileage. If that service is not in your budget then you will need to know how to change the wheels on a car yourself.
