Temperatures and Tire Pressure: An Important Annual Tire Consideration

PressurePro TPMS on Rigid Haul Truck

Whether you operate a truck that runs on a standard set of tires or you're responsible for heavy equipment that operates on truly big tires, the onset of winter brings around an annual tire consideration: the relationship between tire pressure and air temperature.

During the dreaded Polar Vortex of 2014, men and women across North America noticed their tire pressure warning lights flicking on with increased regularity. That's because as ambient air temperatures drop, a tire's PSI will drop as well.

There's actually a clear scientific explanation for this phenomenon.

...a given volume of air will expand or contract as its temperature increases or decreases. In truck tire terms, for every 10-degree change in air temperature, tire inflation pressure will change by 1-2 psi (up with higher temperatures and down with lower). (Trucking Info)

Because we know our readers are well-trained professionals already well-accustomed to handling the variations of the seasons, we know that this news will not come as a surprise to many of you. We just seek to remind you to take extra care during the winter months in order to ensure optimum personal safety and increased tire life.

Drivers of long-haul trucks are likewise encouraged to take special care, since driving on low tire pressure will not only negatively affect gas mileage while simultaneously increasing tire wear; but driving on under-inflated tires could also lead to increased friction resulting in a blowout.

Don't forget that we also carry PressurePro's Tire Pressure Monitor System and can help you get it installed on your heavy equipment and next set of OTR tires. A TPMS system provides real-time tire pressure and tire temperature data to the heavy equipment operator.

No matter the season, remember that we carry a full range of OTR tires for all of your farming, trucking, and mining needs. Please feel free to contact us for the best deals.
