Some drivers are under the impression that as long as their tires look fine that they are fine. The truth is that overinflated tires can be just as dangerous as underinflated tires, not to mention the fact that improperly inflated tires can seriously suck up your gas. Check your tires at least every three months and make sure that you have your tires regularly rotated so that they can wear out evenly.
You may not think very much about your windshield wipers, but you have to realize that they are pivotal in being able to see clearly and avoiding accidents. Imagine being involved in a serious accident that could have been avoided if you had simply changed your windshield wipers. It's best that you change your wipers in the fall since they've been baking in the hot summer sun and so that you'll be ready for any snow that the upcoming winter has in store for you.
If you have a used car that's a more recent model, then chances are good that you don't really need to spend money on a tune-up. The reason for this is that a computer controls the ignition timing, you no longer have to adjust your valves and you don't have to mess with the carburetor. The only things that you really have to worry about are the spark plugs, which can last roughly 100,000 miles. Rather than spend your money on a tune-up that you don't need, you'll be better off saving that money up for preventative maintenance and service.
Take out time to read the owner's manual for your new vehicle so that you'll know what kind of service your vehicle needs and when it needs it.
