How to Check Tire Pressure

Tire pressure is among the most overlooked safety aspects on your vehicle. Many people just assume their tires are fine and that they will be safe because they look okay. Is it sporadic to see someone check their tire pressure or place their figures on the tire and feel for irregularities and roundness?

Proper tire pressure will extend your gas mileage, make your suspension and brakes system last longer, and it will develop your gas mileage. According to AAA, it is absolute to have your tires condition, and pressure checked for safety each time you are fueling your car and before any vacations or long drives.

Importance Of Tire Pressure

When your tires don't have enough pressure in them, it can reduce the safety of your vehicle while driving, limit its performance, and result in higher operating costs. First, low pressure can reduce traction and make the tires less responsive to your steering commands. During bad weather, this can lead to traffic accidents.

Second, if you have ever driven your car when the pressure is low, you may have noticed a sluggish response. This is due to a gripping reaction that the tires are having on the road, often because of worn treads. Third, it's estimated that motorists burn through 5 million extra gallons of gas each day as a result of low pressure. The reduction in fuel efficiency drives up the cost of operating your car.

​How To Check Tire Pressure

First, you'll need to buy a gauge. A digital model that offers an accurate reading of the pressure. If possible, check it before driving your car. When you drive, heat builds in your tires, and it can gradually increase the pressure within.

You'll notice a small cap that covers each of the air valve stems. Remove the caps and place them next to you. They tend to disappear, so you might want to put them in your pocket. Next, place your tire gauge on the valve stem and press in. You'll hear a momentary hissing before it connects snugly. A couple of seconds should be long enough to get an accurate reading of the pressure. Write it down for each of your tires.

Before you fill them with air, take a look at your car manufacturer's handbook. It should list the recommended pressure levels. Sometimes, the recommended levels will be the same for all four tires.

Other times, the levels for the front will be different than those for the rear. Once you have checked the air pressure and you know the manufacturer's recommended levels, you can visit any gas station to fill them. Most stations will charge a few quarters for the compressed air, so bring some change with you.​

How often should you check your tire pressure?​

You should check it at least once a week. You should also check it before going on a longer trip.

How do we check the tire pressure?​

On the side of the tire, it states what the size of the tire is. You can also check your owner's manual. It will also state what the air pressure inside of the tire should be at. It should look something along the lines of 35-PSI or 40-PSI.

Remove the air cap from the valve stem. Take your pressure gauge and apply it to the valve stem. The tire pressure gauge will indicate how much pressure the tire has. Be sure that it reads the same as what your tire PSI indicates. Also, be sure that all four tires have the same tire air pressure or PSI reading.​

How do you inflate your tires to the proper PSI level?​

There are two ways:

  • If you have your air compressor, you can simply attach the hose to the valve stem and fill the tire with air. Be sure not to overfill. Be sure to take your tire pressure gauge and check the level.
  • If you do not own your air compressor then simply visit the nearest gas station and look for 'AIR.' Once again, be sure you have your tire pressure gauge with you so that you can have your tires filled to the correct PSI levels.

Over-inflated tires are not as common but can cause an equal amount of damage to the tire. Too much wear noticed in the center of the tire shows that the air pressure is consistently too high.

Improperly inflating tires or not using a gauge is a common mistake, which can have a high impact on your tires. Over-inflated tires can cause internal damage to the tire or become more prone to flats as well, as the typical hard surface of the tread has been compromised.

The following are some tips which you can look at to see if your tires have the right amount of pressure:

  • There should be a sign on the inside of the driver's door of your car or in the glove box indicating the correct tire pressure for your car. In case you cannot find it, call your car company and get the accurate number from them immediately.
  • Though some stickers will not specify 'cold tire pressure,' you need to ensure that the tires are cold, which means that they haven't been used for the past few hours.
  • The psi number marked on the tires stand for the maximum pressure that the tires can undertake. You need not consider it to be the ideal pressure for your car tires.
  • To know the tire pressure, always use a digital gauge. It is the best way in which you can get the exact pressure and settle the pressure of the tires accordingly.

Final Verdict

Checking the pressure of your tires often can help keep you safer on the roads. It will reduce the wear on your tires. Continuous driving with low tire pressure can cause the belts within the tires to warp or break.
