Proper Inflation
Maintaining proper air pressure is the single most important thing drivers can do for their tires. In the space of just one month, a tire can lose 1 kg of air pressure.
It is important to check the air pressure of your tires regularly to make sure your tires are neither under- nor overinflated.
Underinflation is the worst enemy your tire can have. It causes increased treadwear on the outside edges (or shoulders) of the tire. It also generates excessive heat, which can reduce tire life. Finally, it reduces your fuel economy by increasing rolling resistance — soft tires make your vehicle work harder.
Overinflation is also detrimental to the tire. Too much air pressure causes the centre of the tread to bear the majority of the car's weight, which leads to faster deterioration and uneven wear. Any kind of uneven wear will shorten the lifespan of your tires.
To find the proper air pressure for your tires, look in the vehicle owner's manual, on the sticker on the driver's side doorjamb or in the glove box. If you buy new tires, be sure to learn the correct pressure from your tire Retailer or the owner's manual of your vehicle. Check your pressure at least once a month, and use a high-quality air gauge.
