Keeping your tires at the proper pressure isn't just about fuel efficiency—it's a safety thing. I check mine monthly with a simple gauge, and it makes a huge difference in how the car handles, especially on wet roads. Under-inflated tires wear out faster and can overheat, while over-inflated ones make the ride harsh and reduce grip. A quick look at the sticker inside the driver's door frame tells me the right PSI.
