Final answer:
The highway tire pressure of P-23 is 110 PSI, thus the correct option is D.
Explanation:
The highway tire pressure of a vehicle is an important factor to consider for optimal performance and safety. In this case, the tire pressure of P-23 is 110 PSI (pounds per square inch) on the highway. This means that the air pressure inside the tire should be 110 pounds per square inch to maintain the correct level of inflation.
To understand the significance of this tire pressure, it is important to first know the purpose of tire pressure. The air inside the tire acts as a cushion, absorbing the shocks and impacts of the road. It also helps to distribute the weight of the vehicle evenly, allowing for better handling and control. If the tire pressure is too low, the tire can become deformed and cause uneven wear, reducing the lifespan of the tire. On the other hand, if the tire pressure is too high, it can lead to a harsher ride and also cause uneven wear.
Now, let's take a closer look at the calculation of the highway tire pressure for P-23. The recommended tire pressure for a vehicle is usually specified by the manufacturer and can be found in the owner's manual or on a sticker located on the driver's door jamb. In this case, the manufacturer has recommended a tire pressure of 110 PSI for P-23 on the highway.
To ensure that the tires are at the correct pressure, it is important to check them regularly, especially before long trips. To do this, you will need a tire pressure gauge. Simply remove the valve stem cap from the tire, place the gauge on the valve stem, and press down until you get a reading. Compare this reading to the recommended tire pressure and if it is lower, add air until you reach the recommended pressure.
It is also important to note that tire pressure can vary depending on the temperature. As the temperature increases, the air inside the tire expands and the tire pressure increases. Therefore, it is recommended to check tire pressure when the tires are cold, preferably in the morning before driving.
In conclusion, the highway tire pressure of P-23 is 110 PSI (D). This pressure is recommended by the manufacturer to ensure optimal performance and safety on the highway. It is important to check and maintain proper tire pressure regularly to ensure the longevity and safety of your tires, thus the correct option is D.
