All tires require constant air pressure to equally carry the weight of the vehicle.Correct tire pressure is a definite requirement in order to assure dependable handling, consistent traction and tire life.
Seasonal temperatures change the air pressure in tires. Cold winter weather will cause the tire pressure to drop. Warm summer temperatures will cause the air pressure to increase. Rule of thumb is a swing in temperature by 10 degrees will cause a 1 lb. change in air pressure, so check your tire pressure as temperatures change, as well as periodically throughout the year.
Check the manufacturer's recommended tire pressure, which can be found in the owner’s manual or on the vehicle placard found in the glove compartment or in the armrest compartment in most cars.
We recommend a good quality air pressure gauge to be kept in your vehicle at all times. Air gauges found at service stations are used daily and may not always record accurate air pressure. By purchasing your own tire pressure gauge, you will always receive consistent readings when you check your tire pressure.
The number one cause of premature tire wear is incorrect air pressure, too much or too little. At Pep Boys, we recommend purchasing valve stems at the time of your tire purchase. A valve stem, like a tire, has a life span. As valve stems are exposed to the different weather conditions and the changes in ozone levels, they have a tendency to become brittle and cracked, causing a loss of tire pressure. The purchase of a valve stem can in add life to your tire purchase.
