While this system is handy, it’s important to remember that the most accurate way to check your tire pressure is with a tire pressure gauge, which you should use anytime you’re preparing for a long drive.
Ensuring your tires are inflated to the correct level isn’t just a great way to keep yourself safe during your drive—it also improves fuel efficiency. In addition, it enhances the way your car handles different road conditions, making it easier to drive.
On the other hand, driving with improperly inflated tires increases your chances of a tire blowout, makes braking less efficient, and even wears your tires down more quickly.
