Here in central New Mexico, we’ve had a long, hot summer. That heat affects your tire pressure, and as the weather begins to cool, your tire pressure may change. Many Dodge and Ram models today have tire pressure monitoring systems (TPMS) so you may even get a notification while you’re driving.
When the outside temperature is high, the air in your tires
expands to take up more volume; likewise, when it’s cold outside, the air takes
up less volume. That change, especially if it’s a rapid change in the
temperature, can make the computer in your car assume that the tire pressure is
low.
In general, for every 10 degree change in the outdoor
temperature, tires can gain or lose 1 PSI (pound per square inch). So in the
Albuquerque area, we often get temperature swings of 30 degrees or more, from
the cool morning temp to the hot afternoon temperature. Tires are made to
handle that swing.
Most tires require 30 to 35 PSI for passenger cars, more for
large trucks. Always follow the recommendations for your vehicle, found in your
owner’s manual.
Keeping tires properly inflated is key to safe and fuel
efficient driving. If your tires are underinflated, not only will your fuel
efficiency be affected, the vehicle may not handle well.
For new tires for your car or truck, for tire repair, to
rotate your tires, or to see if your TPMS system is working properly, see the
service professionals at MelloyDodge’s service department. Our Express Lane offers no-appointment service for basic items.
