It also increases fume emissions. Unfortunately, you will have to refill the car more often. It will adversely affect your budget. The increased discharge comes as a result of the increased energy the underinflated tire consumes to keep your vehicle in full motion.

Other effects of low tire pressure include short tread life. In the worst-case scenario, it can cause a terrible accident. The reason being as the tire continues to rub the ground, friction increases. It eventually hits up and blows up or even separates the tread. It becomes more dangerous when driving on a wet road. Whenever you apply for an emergency brake, the car doesn’t stop immediately. It can cause your vehicle to roll over.

Here Are A Few Tips That You Can Use

Hand Pressure

The fact that you don’t have a pressure gauge should not make you ignore checking on the pressure. You can use your bare hands to know if it is under or overinflated. Press the tire using your hand. If the tire has low pressure, it will become soft. That requires additional pressure. As you increase the pressure, keep on pressing the tire manually. If you feel that the tire is as hard as a rock, then it is overinflated.

Weight on The Tire

If you put maximum pressure on the wheel of your car, a tire with low pressure will deform. To ensure that the tire gets enough pressure, keep on adding gas into that tire until its deforms rate goes to zero.

Eyeball Method

It’s the easiest of all processes; unfortunately, you can’t use it if you are not an expert. If you have the experience, leave the vehicle on a flat surface. Watch the tires at a little distance. Check both sides of the tire. If it is protruding on either side either for a millimeter or even two, it means the tire has low pressure. Inflate more gas but ensure that it doesn’t harden like a rock. That would mean it is over-inflated.

Most of the time, when traveling, many people park their stuff in a hurry. Unfortunately, they forget to carry essential things like a pressure gauge. If you find yourself in such a situation, worry less. All you require is to know how to put air in tires without a gauge. So how can you achieve that?

Tips Of Putting Your Tire’s Air If You Don’t Have A Gauge

Remember, each car has manufacturers’ recommendations of the amount of air each tire should have. The rage requirement of your car should be in your figure tips. If you lack a gauge, putting enough air on each tire could be tricky. What should you do?

Visit a Gas Station

If the gas stations near you an old-style, you will have to use the old-style machine available. You will have to monitor your tires’ air pressure using the small dial that is mounted on the air hose. If it has a modern machine, expect it to display a PSI on the digital display.

In most cases, you will find that many gas stations have a device that is an air compressor-style tire inflator. You can find them somewhere outside. They have a way of measuring the pressure in your tire. Once you connect, they show you the current pressure of your tire. As you continue filling the gas, as it keeps updating the reading. You only require being careful not to exceed the manufacturer’s recommendations.

Downloading and Installing An App On Your Phone

Thanks to technology, the majority of people can now afford a smartphone. Did you know that a smartphone can help you inflate the tire? Don’t take that literally.

Allow the app to cross-reference the tire’s shape with the database of multiple tires of similar brands. Allow it to compare various states of inflation.

As you inflate the tire and allow the app to compare, it will finally give you the best resemblance of that particular brand that has the correct range. It is not a very accurate method, though if you have no better option; it’s a method to consider.

Physical Checks

In this method, you have to rely on your eyes. Once you hook the tire to the air pump or even a compressor, watch it as it continues inflating and use your judgment. Some will stop when they see that the surface of the tire no longer touches the ground. Others will have to use their hands and stops once the tire hardens. Remember, if the tire has low or excess pressure, it can cause a nasty accident. If you are using this method, be careful not to overinflate it.
