How important is the tire pressure?.

Tires are one of the most necessary parts of the car. It carries the weight of the entire vehicle taken down the road and absorbs vibrations from different road surfaces to the car body. Good or bad handling of the vehicles depends on tire condition, too. Correct tire pressure is, therefore, very vital. If it is too high or too low could cause unsafe driving.

If over-inflating the tire, it will cause wear at the center section of the tires. The tire will only partially touch the road surface. The edges of the tire are less worn because it does not contact the road throughout the tire surface.

And vice versa, if the under-inflated tire will cause the center of the tire not being able to touch the road. Therefore, causing the tire to wear out only on the edge of the tire. Besides more fuel consumption, inflating the tire will cause the sidewall to move up and down more than usual. It may cause the tire to heat up and explode if running at high speed.

You must keep tires air pressure at the proper spec as advised by the car or tire maker.

How to check your car tire pressure?.

The car owner manual shows how much tire air pressure is using on your car model, in PSI, kPa, or BAR unit. You also can check at a sticker on the doorjamb. Mostly on the driver side like in the below picture. It shows pressure units both when the car has a regular load or full load with the passengers.

You should check when tires are in cold temperature, for example, before a drive in the morning or after park your car for at least 3 hours. You will get incorrect or high pressure than actual if checking when tires are still hot. Pressure air in car tire will vary by ambient temperature, one psi per 10 degrees F, plus and minus.


Usually, the driver or car owner should check it once a month at least or before take a trip. They can use tire pressure gauges sold at department stores or car accessories stores.

There are many types of pressure gauges, either pencil gaugedial gauge, or digital tire gauge.   Otherwise, you can check and inflate with an automatic air inflator at a gas station. However, we recommend buying one for your car. This gauge is more accurate and more durable. If unnecessary, it should not bring your vehicle to check and inflate from the gas station, in which the pressure gauge may not function 100% correct.

what is tire pressure monitor system or tPMS?.

At present, car makers install TPMS or Tire Pressure Monitoring System in their cars, especially in the U.S.A. . TPMS is the electronics devices installed both inside the rims and wheel’s air valve caps.

The pressure sensor of each wheel will transmit a signal to the car computer and show on the car cluster display anytime the driver wants to check, and it will automatically alert, as well.

The pressure units are PSI, kPa, or BAR. The driver or car owner who lives in other countries where they do not have a law like the U.S.A. might buy TPMS and install separately. Several TPMS devices are selling online. It is so easy to install. Just remove the wheel valve cap and replace it with sensors. The driver then can monitor air pressure via mobile phone or its device display.

It is useful and makes you safe drive no matter where you go, in the city or takes a long trip.

is it necessary to have tire inflator and sealant in your car?.

Some car brand provides you the run-flat tires. You could drive further than 100 miles if the tire blew up. It is commonly come with a luxury car like BMW, BENZ, not for an economy car.  

In the emergency case, your car tire flatted during the drive to work or take a trip and does not have a spare tire. It may be a problem from a screw, nail, or sharp piece of metal on the road. You could fix this as temporary before the drive to a tire shop. A tire inflator kit is useful for this situation. You can fill tire sealant simultaneously with the pumping air.

  The sealant will fill a leak, and you can drive for several miles to find a tire shop to fix it permanently or change a new tire.   

Most drivers always drive safely, but they can’t predict what will happen on the road. No one wants to pay the cost of a tow truck that more expensive than a Tire inflator kit
