Keep Your Tires Properly Inflated (Auto Repair)

Underinflated tires consume about 1 mile per gallon of extra gasoline. They wear out faster, too. Air costs nothing, so make sure that your tires are getting all they need. Chapter 19 shows you how to “read” your tires’ treads to see whether they’re properly inflated and how to find the proper pressure range on the sidewalls of your tires. To get an accurate reading, always put air in your tires in the morning before you drive the car (except to get to the nearest air pump, of course). After a car has been driven for a while, the tires heat up and the air in them expands.
Get the snow tires off the car as soon as possible, too. They consume a lot more fuel. Next time, buy all-weather tires.
