Tire Inflation
One of the most important,
and often the most neglected, pieces of equipment
on your car is your tires. They are your only contact
with the road, and if they aren't properly inflated,
you could easily lose that contact. A properly inflated
tire provides you with the best acceleration, braking
and steering control.
Proper tire pressure varies with the type of tire and the type of vehicle. Check your owner's manual or the sidewall for the proper pressure. Generally, 30-33 pounds can be used for an average-sized passenger car. Remember that tires lose air pressure at the rate of 7 kpa (1 pound per square inch) for each 5ºC (10ºF) drop in temperature.
You should check your tire pressure at least twice a month, or before a long trip. The best time to check your tires is when they are cool.
Over-inflated tires
will wear faster in the center. Under-inflated tires
wear on the edges. Neither provide the best traction
or gas mileage.
Tires should be replaced when the tread wear indicators start to show. Proper inflation and tire rotation will let your tires last a lot longer.
