It's not only on safety grounds that you have to keep the tires at the right air pressure – there is an economic reason too because correctly inflated tires use less gas. Any time a tire is not close to the correct air pressure there is more rolling resistance thanks to the larger tire surface touching the highway. This creates a mechanical drag towards the engine which needs to be dealt with by using more gas per mile. By upholding your tires inflated properly you can end up saving up to 10% off your gas costs. A tire with pressure below the proper level is likely to spread outward so your sidewall starts to come into contact with the ground. If you have too little air pressure the tire will run on the sidewalls, and the side walls are not meant to be having contact with the road. When this occurs you can drastically decrease the life of your tires and will even cause blow outs while your driving.

Some prefer to go the extra mile and endeavor to keep everything in 'as new' condition outside and inside the car maybe spending half the weekend carrying this out. But one important thing that generally seems to always get forgotten about is examining the tire pressure. In this post we will discuss the importance of maintaining appropriate tire pressure.
