The drop in temperatures and the age of cold not only affects energy consumption or the need to bring out warmer pajamas from the back of the closet. It also affects aspects such as the condition of our car’s tires. According to the old farmer’s almanac, the first autumn frosts and cold weather have already arrived to stay. Therefore, it is important to ensure the condition of the tires, as well as their pressure, taking into account the recommendations of the American Automobile Association (AAA).
The maintenance of compressed air inside the wheels depends on thermodynamics, as explained by the AAA, and it is essential to keep the levels at the proper pressure to ensure road safety. Pressure can be measured with a pressure gauge, which can be found at service stations. If you do not have any pressure gauge, you can also examine your wheels to make sure that the tires are not deflated.
Safety on the road
According to the Old Farmer’s Almanac, the first autumn frosts and cold have already arrived in the United States to stay. The drop in temperatures and the arrival of autumn and winter do not only affect the amount of the energy bill, but also relate to other aspects such as the condition of our car tires. According to the American Automobile Association (AAA), “As temperatures drop, tire pressure can decrease by one to two pounds per square inch for every 10-degree drop”.
Senior automotive manager David Bennett explains that “This is simply due to how air molecules react to temperature changes. Air molecules do not move as quickly in colder climates, causing air pressure to decrease. Flat tires can contribute to longer braking distances, reduced road grip, and worse gas mileage”. For all these reasons, the AAA advises drivers to check their tire pressure to ensure road safety.
Checking tire pressure
Both experts and AAA recommend that tire pressure checks be done once the tires have cooled down. After waiting for two to three hours, remove the valve stem cap and press the gauge onto the system. What is a gauge? It is an instrument that measures the pressure of gases or liquids within a closed system. According to AAA, there are 3 types for measuring tire pressure:
- Stick pressure gauge: forms a rod that slides out of the valve when pressed onto the system. It is relatively inexpensive and easy to store in your glove compartment. Drawback? It can be difficult to read.
- Dial pressure gauge: Used in the same way as the pressure gauge, but more expensive and difficult to store in your vehicle. Similar to a blood pressure cuff, the dial pressure is easier to read than the pressure gauge.
- Digital pressure gauge: The most accurate of the three. The dial pressure indicator has an electronic display instead of the lever or dial.
How to measure without a gauge?
You may find yourself in a situation where you cannot access a tire pressure gauge. However, you should not worry, as there are other ways to check if your tire is properly inflated.
- Changes in driving: If your vehicle does not drive as smoothly or is clumsier than usual, makes noises in the steering wheel, or has difficulty turning, the tire pressure may be low.
- Examine the wheels: the tires will sag where the rubber meets the road.
- Load weight onto the vehicle: if the tire seems to flatten when more weight is added to the car, the tire may be underinflated.
- Feel the wheels: If the tire gives way when you press it, it is very likely that it has low pressure.
Although such alternatives exist, remember that the most reliable method is to use a tire pressure gauge, or failing that, to consult a professional mechanic who can ensure that your tires are in perfect condition.
