Regular checking of the tires can help you avoid the inconvenience of having to sit there with a flat tire and also give you the information on potential issues in the steering and suspension system before it could cause a significant amount of damage. The tires used on this vehicle have bands in them which are 1/2-inch wide and they will form when the tread depth becomes 1/16-inch which is a sign that they are worn off. A tread depth indicator is a simple, low-cost device that can be used to monitor tread wear. Record any unusual tread wear, any front end problem like cupping, flat spots and uneven wear may be signs of front end alignment or balance problem and needs to be addressed at a tire shop or service station. Be on the alert to check the cuts, punctures, and embedded nails or tacks because a tire can contain the air pressure temporarily, or can leak after a nail has lodged in the tread. In case of a slow leak and it continues, inspect the valve stem core at the top to make sure it is tight and the tread to check whether it has objects or plugs which might be leaking. The presence of a suspected puncture can be confirmed by sprinkling soapy water solution on the puncture since the presence of bubbles will indicate a leak; a tire shop is normally able to fix the puncture unless there is something wrong with the puncture. Check the inner sidewall of every tire to indicate the possible leakage of brake fluid and in case it has any, examine the brakes immediately. The proper air pressure will not only prolong the life of the tires, but will also increase the miles per gallon and the overall ride quality and therefore a tire pressure gauge is necessary because no one can be able to estimate the air pressure using the look of the tire. Never check tire pressure when tires are hot that is, the vehicle has not traveled more than a mile during the three hours before checking the pressure because it is normal to find a four to eight pound pressure increase when hot. Cut the valve top off the wheel or hubcap and insert the gauge firmly on the valve stem and record the reading and compare it to the recommended tire pressure indicated on the tire placard on the door that is at the driver side. Install the valve cap again to ensure the valve stem mechanism is kept out of the dirt and moisture, inspect the four tires, and put in more air as needed to bring the pressure up to the recommended amount. Also maintain the spare tire to the pressure that is announced on the tire sidewall.
