Answers to Four Common Questions About Tire Pressure
You probably already know that tire pressure is important when it comes to driving safely , but it can also cost you money if you don’t keep an eye on it. This video explains what you need to know about tire pressure.
In this video from Engineering Explained YouTube, Jason Fenske explains how temperature affects tire pressure, how tire pressure affects tire grip, how under-inflated tires cost you more, and how improperly inflated tires wear out much faster. … For example, usingthe ideal gas law , you can assume that the tire pressure drops 1 psi when the ambient temperature drops 10 degrees Fahrenheit. If the temperature rises, so does the PSI of the tire. This can be dangerous in winter because you can drive on under-inflated tires if you don’t check them in the summer. When it comes to tire grip, lower tire pressure can give you more on a warm, dry day. However, if you are driving on wet surfaces, the low tire pressure greatly increases your chances of aquaplaning.
Fenske explains that if you want to maintain maximum fuel economy in your car, it’s best to avoid riding on under-inflated tires. Less tire pressure means more rolling resistance, which means more energy is required to maintain a smooth ride. Finally, inadequate tire pressure can lead to faster tire wear than usual and a significant reduction in tire life. An over-inflated tire will have more wear in the center of the tire, and an under-inflated tire will have more wear on the outside of the tire. The bottom line is that you should always check your tire pressure and adjust it to the manufacturer’s recommended levels – not only for your safety, but also to save money in the long run.
