It’s a pretty common occurrence once winter hits: the temps drop, and your tire pressure light comes on. Or you notice a sag to your normally perfectly inflated tires. Typically, winter temperatures go about -40 to -50 °F below summer’s average temperature, which affects your tires’ PSI level. Tires lose about 1 PSI for every 10 °F change. To make it even more confusing, your tire pressure could be lower in the morning than in the afternoon after a day of driving and warming temps.
We’ll make it easier for you – try checking your tire pressure at least once every month. To get the most out of your tires’, you should follow the manufactures recommended PSI level, which you can find on a sticker on your driver’s side door or in the manual. If you have a newer car, a lot of the time your dash will warn you when it goes under or over the recommended level. If your tires are under- or over-inflated, you risk losing traction easily on snowy roads, lower gas mileage, and uneven tread wear.
Manufacturers have predicted the common rise and fall of temps in a day, and their recommended range covers that issue. Even if there’s a drastic 20°F rise from the morning to afternoon, if your tires are at the ideal PSI, then you should be fine. Maintaining an ideal PSI in each of your tires will ensure they will hold up their durability, so you get the most out of them.
