Article: Regularly check the mechanical features of your car, making sure to include the headlights and taillights, the brakes and the suspension.  If you don't feel comfortable doing these things yourself, send your car to a mechanic. The failure of any of these components can create a dangerous situation while driving. For example, if your wheel falls off and you have an accident, your insurance company will find that you are at fault.  Minor things count, too. Change windscreen wiper blades when they begin to streak the windshield during use. Also keep your windscreen washer reservoir filled regularly to clear mud or debris from your windshield. This will give the best traction, mileage, and performance. In the UK, it's a legal requirement to have properly inflated tyres at the correct tread depth.  Make sure the tyre pressure is even -- uneven pressure can lead to poor performance or even a blowout. Replace worn tyres. Remember that wet traction deteriorates before tread wears to its legal limit because the water has only smaller places to be squeezed out to; replacing at 4/32 can be wise. Check your spare when you check your four tyres. Did the previous owner forget to tell you about that time he used the spare? If the answer to that question is yes, then get a new one.

What is a summary?
Regularly check for any mechanical issues. Maintain your car properly. Keep all four tyres properly inflated.
