Inflating proper air pressure is very important for the tire and its life. Tires should be inflated to the pressure recommended by the manufacturer of your car. Following the vehicle manufacturer’s recommended tire size and inflation pressure is a simple thing and information can be found in the owner’s manual. This information can also be found in these areas, edge of the driver’s door, door post and inside of the glove box door.
An under inflated tire can experience excessive side wall flexing which results in high heat generation in a short time and reduction in load carrying capacity. Under inflation also leads to a reduction in fuel economy. Inflating your tires to the maximum pressure specified on the tire side wall can extend tire life and improve your fuel economy.
It is not possible to ascertain whether a tire has the correct air pressure just by looking at it. This is especially true with radial tires.
The best time to check tire pressure is in the morning. Use a good quality air pressure to check your tire at least every two weeks and before any long trips. Always check the pressure when the tires are cool (if the vehicle has been driven less than 1.5km). If the car has been driven, allow the tires to cool for a few hours before checking the pressure. Do not bleed or reduce tire pressure when tires are hot. A tire air pressure will automatically increase as its internal temperature increases. This increase is normal and should not be adjusted.
Tire pressure should be increased when your car is carrying extra weight, such as on a vacation trip. An increase of 4psi (28kPa) over the car manufacturer’s recommended cold tire pressure is usually sufficient. Remember, check and adjust inflation only when tires are cool.
Be sure the valve caps are screwed down finger-tight. Valve caps should have a rubber seal to provide a secondary air seal and keep dirt and moisture out of the valve core. A new valve assembly should be installed whenever a tire is placed.
If the valve caps are not in place, fine particles of sand may get trapped in the valve openings and air would leak out slowly through the small tiny holes causing possible tire failure over a period of time
