Tire Care and Spark Plugs

Let's wrap up our maintenance rundown with tire care and spark plugs. Taking care of your tires and spark plugs is super important for both safety and performance. First up: tires. Regularly check your tire pressure using a tire pressure gauge and inflate them to the recommended pressure (found on a sticker inside your driver's side door or in your owner's manual). Check your tire tread depth using the penny test (place a penny with Lincoln's head upside down in the tread; if you can see the top of his head, your tires need to be replaced). Make sure to rotate your tires every 5,000 to 7,500 miles to promote even wear. Spark plugs are another important component. These small but mighty components ignite the air-fuel mixture in your engine's cylinders, and they can affect your engine performance. Replace your spark plugs at the recommended intervals (usually every 30,000 to 100,000 miles, depending on the type of spark plugs and your driving habits). This can improve fuel efficiency and engine performance. Properly inflated tires provide better fuel economy, handling, and safety. Worn tires can lead to reduced grip, increased stopping distances, and a higher risk of accidents. Spark plugs wear out over time. Worn spark plugs can lead to reduced fuel efficiency, rough idling, and difficulty starting the engine. By staying on top of these essential maintenance tasks, you can ensure that your Nissan Sentra continues to provide you with years of reliable service.
