With millions of Americans hitting the road this summer for vacations and family outings, it's important to take one simple step to make your car work as efficiently as possible: Be sure your tires are inflated properly. According to the tire manufacturer Goodyear, Americans waste about $2 billion every year because of improperly inflated tires. To find your recommended tire pressure, look for the sticker near the driver's seat when you open the car door. The air pumps at some gas stations will tell you your current pressure, and you can inflate your tires until you reach the optimal inflation rate for your vehicle.
